Captain's Log — May 9, 2026

Saturday morning in the Keys and the spring ridge is still holding, but the breeze has stepped up a few knots compared to yesterday’s glass. We knew this was coming — Friday’s forecast called it, and the 4:17 AM NWS Key West update confirmed it. Southeast winds at 10 to 15 knots, seas building through the day. Not a blown-out day by any stretch, but the window of opportunity shifts.

The good news: the upper-level high pressure is stubborn. Deep layers of dry air over South Florida keep rain and thunder chances near nil through the weekend. Clean water, clear skies, no weather drama. The Gulf Stream is still parked at 10 miles off Alligator and 8 miles off Molasses. The fish are here. You just have to work the conditions.

Let’s break down the day reef by reef.

NOAA Marine Forecast Summary

Source: National Weather Service Key West marine forecast, issued 4:17 AM EDT Saturday, May 9, 2026

• Synopsis: Gentle to moderate breezes start the weekend. High pressure over the western Atlantic dominates the pattern. Deep layers of dry air keep rain and thunder chances low through the weekend. A lingering frontal boundary next week may bring a slight uptick in rain chances
• Wind: Southeast to south winds near 10 knots, increasing to 10 to 15 knots through the day
• Hawk Channel seas: 1 to 2 feet — building from a light chop to a moderate chop
• Offshore Straits: Around 2 feet, building to 2 to 3 feet by night. Wave detail: East to southeast 2 feet at 4 seconds — short-period wind wave
• Weather: Dry — deep layer of dry air over South Florida. A slight chance of showers overnight
• Pattern: Gentle to moderate breeze, high pressure dominating, settled weekend. This is a stable spring ridge with moderate SE flow

Reef-by-Reef Breakdown

Molasses Reef (Upper Keys)

Zone: Hawk Channel / Straits of Florida

The premier upper Keys reef is fishable today, but the SE breeze at 10-15 knots means you’re working a consistent drift. The reef structure in 40-60 feet breaks the wind and current enough to make chumming productive.

• Wind: SE 10 to 15 knots — organized breeze, not gusty or sloppy
• Hawk Channel seas: 1 to 2 feet — manageable chop
• Gulf Stream edge: 8 miles southeast — tightest offshore shot on the line
• Water clarity: Holding clean — the settled pattern hasn’t churned things up
• Bottom structure: Classic reef face with ledges and coral heads
• The play: Set your chum slick on the upwind side of the reef. The consistent breeze works in your favor — it lays a clean, predictable slick along the structure. Yellowtails in 40-60 feet, with the morning incoming tide giving you the best window. If you want offshore, the 8-mile run to the edge is manageable at 2-foot seas

Conch Reef

Zone: Hawk Channel

Conch holds its own in a breeze. The organized southeast flow pushes clean Atlantic water right onto the reef face, concentrating bait along the ledges.

• SE wind at 10-15 knots creates a steady, predictable drift along the reef axis
• Seas: 1 to 2 feet in Hawk Channel — comfortable for any center console
• The incoming tide (5:31 AM high past, next high at 4:16 PM) gives you a late afternoon window that aligns with the peak of the breeze
• Target species: Yellowtail snapper on the chum slick in 40-60 feet. Mutton snapper deeper on structure in 60-80 feet. Cero mackerel working the edges. The steady breeze drives baitfish against the structure, which pulls the predators in
• Visibility: Good — settled pattern, clean water

Davis Reef

Zone: Hawk Channel

Davis handles southeast wind well. The reef axis runs roughly parallel to the wind direction, meaning you can drift the structure with the breeze or anchor upwind and chum into the slick.

• Wind: SE 10-15 knots, seas 1-2 feet
• The 60-80 foot ledge is the proven zone for muttons and cobia
• Drift fishing is productive — the steady breeze gives you a consistent, predictable drift speed
• Chumming for yellowtails on the incoming tide is the primary play
• Bottom structure: Consistent ledges that concentrate bait — the steady current enhances the bite
• Saturday bonus: Less pressure than Molasses, which often means better quality fish

Crocker Reef

Zone: Hawk Channel

Crocker is a sleeper in moderate wind. The reef structure creates enough lee to make bottom fishing comfortable, and the steady current from the SE breeze keeps the bite active.

• The building breeze to 10-15 knots is manageable
• Bottom fishing in 50-70 feet — yellowtails and muttons chewing on the structure
• The lee side of the reef offers a more comfortable option if the wind is pushing hard
• Kingfish patrol the edges — the steady wind pushes bait against the drop-offs, and the kings follow
• Less boat traffic means less competition for the productive spots

Alligator Reef

Zone: Hawk Channel / Straits of Florida

The mid-island anchor reef and best offshore launch point. The 10-mile run to the Gulf Stream edge is still comfortable, but choose your window carefully.

• Gulf Stream edge at 10 miles — the go-to for mixed reef-offshore trips
• Hawk Channel seas: 1 to 2 feet — light chop
• Offshore Straits: Around 2 feet — comfortable for the run
• The morning window is the smart play: get out early, hit the reef on the incoming tide, decide on offshore by mid-morning before the seas build
• The lighthouse structure holds bait — always a reliable starting point
• Target species: Yellowtails on the reef face in 40-60 feet. Mahi at the stream edge on weed lines and color changes. Kings working the drop-offs
• The afternoon: SE breeze at 10-15 knots with 2-foot seas offshore — still manageable but the ride back will be wetter than the run out

Tennessee Reef

Zone: Hawk Channel

Tennessee is a reliable option when the upper Keys are busy. The wind pushes clean water over the structure all day.

• Wind: SE 10-15 knots, seas 1-2 feet — consistent but fishable
• 60-80 feet is the target zone for muttons and yellows
• Consistent bottom action — the steady breeze-driven current keeps the bait moving and the fish active
• Less boat traffic makes this a smart Saturday choice
• The lee side provides shelter if the wind is heavier than forecast

Tides & Water

Tides, Islamorada (Upper Matecumbe Key, Florida Bay)

• Low: 12:13 AM at 0.1 ft (past)
• High: 5:31 AM at 0.3 ft (past)
• Low: 11:00 AM at 0.3 ft
• High: 4:16 PM at 0.5 ft

Tides are modest today — this is a Last Quarter moon pattern with a smaller-than-average range. The 4:16 PM high is the strongest water movement of the day at just 0.5 feet. The 11:00 AM low at 0.3 feet drains the flats and pushes fish into channels and cuts.

The midday outgoing (11:00 AM) is a transition window — water pulling off the flats, fish concentrating in channels. The 4:16 PM incoming is the second-chance window for the afternoon crowd.

Key windows for today:

• Morning (pre-11:00 AM): Work the outgoing on the reef. The last of the incoming push from the 5:31 AM high has already passed, so the morning is a falling tide that pulls fish off the flats
• Midday (11:00 AM — 2:00 PM): Low tide slack. Fish will be concentrated in channels and cuts. This is the slowest window of the day
• Afternoon (2:00 PM — 6:00 PM): Building incoming tide peaking at 4:16 PM. This is the afternoon money window. The incoming pushes clean water and bait onto the reef face

Water Temperature

• Molasses Reef buoy (historical): May average ~81-83°F
• Peterson Key buoy (closest live): ~87°F in the backcountry shallows (shoaling hot)
• Reef tract estimated: 80-83°F — solid spring numbers on the reef face
• Gulf Stream: Carrying spring heat at 83-85°F
• Florida Bay: Running hot in the shallows — the shallow basins are cooking in the spring sun
• Water clarity is good for a 10-15 knot breeze day — expect 20-30 foot visibility on the reef

Moon Phase

• Third Quarter — moon rose after midnight, setting midday
• Modest tide range — the 0.5-foot afternoon high is the day’s strongest movement
• The 4:16 PM incoming is the fish-moving window
• Last Quarter patterns often mean better late-afternoon and evening action as the moon rises through the afternoon

Species Outlook

Yellowtail Snapper

Outlook: Good to Excellent

• The SE breeze at 10-15 knots is actually helpful for chumming — it lays a clean, organized slick
• The morning outgoing tide (falling from the 5:31 AM high) pulls fish off the flats onto the reef face
• 40-60 feet on the reef face is the proven depth
• The consistent breeze means you want to set your chum bag upwind and let the current + wind work together
• This is still the highest-confidence species on the reef

Mutton Snapper

Outlook: Good

• Deeper ledges in 60-80 feet at Davis, Crocker, and Alligator
• The steady breeze-driven current keeps them active
• The 4:16 PM incoming tide should fire them up in the afternoon
• Live bait on structure is the proven play
• The settled pattern continues to hold fish on structure

Mahi-Mahi

Outlook: Fair to Good

• Gulf Stream edge is reachable at 10 miles off Alligator
• 2-foot seas offshore is comfortable — the ride back is wet in the afternoon chop but doable
• May is building — mahi numbers increase week over week
• Look for scattered sargassum, temperature breaks, and working birds
• The sustained SE flow should be consolidating weed lines along the stream edge
• Tip: Get out early before the seas build. The offshore run is best pre-noon

Kingfish and Cero Mackerel

Outlook: Good

• Kings are consistent on the reef edge in settled conditions
• The steady breeze concentrates bait along the drop-offs
• Cero mackerel are thick on the structure — flashy spoons, ribbonfish, live bait
• The consistent drift makes trolling the reef edge productive
• Day-savers for trips where the bottom bite is slow

Sailfish

Outlook: Fair

• Late spring — not peak season, but scattered fish are around the stream edge
• Best window is early morning before the breeze builds
• The stream edge at 8-10 miles is the target zone
• Ballyhoo or live bait on the edge if you want to scratch one
• The settled conditions and stable water temps support scattered sail activity

Blackfin Tuna

Outlook: Fair

• May transition — scattered schools around the stream edge
• Look for bird activity and surface action
• The afternoon is less likely with the building breeze
• Morning window is your best bet

Tarpon & Backcountry

Outlook: Good

• Florida Bay today: SE to south winds near 10 knots, becoming 10 to 15 knots through the day. Bay waters a light chop, building to a light to moderate chop
• The 11:00 AM low at 0.3 ft pulls water off the flats, stacking tarpon in channels and cuts
• The afternoon incoming (4:16 PM) pushes tarpon onto the flats — sight fishing window in the late afternoon
• The backcountry chop is manageable — a light to moderate chop is fishable
• The outgoing tide in the morning is your prime tarpon window

Captain’s Recommendation

Here’s the call for Saturday, May 9:

1. The reef is the play. The SE breeze at 10-15 knots is a step up from yesterday’s flat conditions, but the reef is still very fishable. Hawk Channel at 1 to 2 feet is comfortable. The wind is organized and predictable — anchor upwind, chum into the slick, and work the structure. Yellowtails and muttons carry the day.
2. Offshore is a morning window play. The Gulf Stream at 10 miles off Alligator is reachable. Seas are around 2 feet in the morning, building to 2-3 feet in the afternoon. If you want to chase mahi and sailfish, get out early and come back before the afternoon chop builds.
3. The midday lull is real. Low tide at 11:00 AM on a modest tide day means the middle of the day is slow. The 4:16 PM incoming is your second window. Plan your day around these transitions.
4. The backcountry is a strong alternative. Florida Bay builds to a light to moderate chop but is still fishable. The morning outgoing tide concentrates tarpon in channels. The afternoon incoming pushes them onto the flats.
5. The ridge holds through Sunday. Sunday is similar — SE winds 10-15 knots, seas 2 feet, drying out late. Monday brings the first real chance of pattern change with a lingering frontal boundary that may increase rain chances.
6. Boat prep matters today. The SE breeze builds to 15 knots by Sunday night. Make sure your anchor holds, your chum bag is rigged for a steady drift, and you’ve got a comfortable ride for your guests.

Short-Range Outlook

Tonight (Saturday)

• East to southeast winds near 10 knots, increasing to 10 to 15 knots
• Seas 1 to 2 feet on the reef, 2 to 3 feet offshore
• A slight chance of showers develops overnight

Sunday, May 10

• Southeast winds 10 to 15 knots, decreasing to near 10 knots
• Seas: 1 to 2 feet reef, 2 to 3 feet offshore, subsiding to around 2 feet
• Similar pattern to Saturday. The breeze settles slightly through the day
• Dry — the upper-level ridge still holds

Monday, May 11

• Southeast winds 10 to 15 knots, becoming variable 5 to 10 knots late
• Seas: 1 to 2 feet, subsiding to 1 foot or less
• Slight chance of showers — first notable rain mention since last week
• A lingering frontal boundary approaches — worth watching. The ridge has been stubborn
• Winds shift light and variable late Monday

Tuesday, May 12

• Variable winds near 5 knots — flat conditions return
• Seas around 1 foot or less
• A chance of showers — the front may stall nearby
• Northwest to north winds develop by Tuesday night — pattern shift

Wednesday, May 13

• Northeast to east winds near 5 knots, becoming variable
• Seas 1 foot or less
• A slight chance of showers and thunderstorms continues
• The post-front pattern settles — calm but unsettled

Final Take

Saturday is a step up in breeze from yesterday’s flat morning start, but it’s still a fishable day if you know where to be when. The reef is the high-percentage play — 1 to 2-foot seas, an organized chumming breeze, and settled conditions that have been holding steady for days. The Gulf Stream is still at 10 miles off Alligator, and the offshore is comfortable in the morning window.

The modesty in today’s tide range means you need to be smart about timing. The 11:00 AM low is a transition point — the morning outgoing concentrates fish, the midday is slower, and the 4:16 PM incoming re-activates the bite.

Plan for the reef, stay flexible for the afternoon incoming, and keep an eye on that Sunday-Monday frontal boundary. This settled spring pattern is still delivering — you just need to read the conditions.

Go fishing.

Midday Addendum — 11:30 AM EDT (based on NOAA 10:52 AM EDT update)

Fresh source: National Weather Service Key West coastal waters forecast, issued 10:52 AM EDT Saturday, May 9, 2026. Midday confirmation is in, and the news is better than the morning read.

What’s changed since the 4:17 AM report

• Wind: Morning called for “SE to south winds near 10 knots, increasing to 10 to 15 knots.” The midday read drops this to Southeast to south winds 5 to 10 knots — lighter than forecast. The gradient hasn’t tightened as expected. Gentle-to-moderate is the actual feel through the afternoon.
• Offshore Straits seas: Morning had seas “around 2 feet, building to 2 to 3 feet” by night. The midday confirmation holds at around 2 feet with wave detail showing East to southeast 2 feet at 4 seconds — short-period wind wave that the 10-15 knot breeze is pushing. The building trend to 3 feet hasn’t materialized yet.
• Hawk Channel: Still 1 to 2 feet — no change, still solid.
• Florida Bay: Morning said SE to south 10-15 knots. Midday says Southeast to south 5 to 10 knots — same downward revision. Bay waters smooth to a light chop.
• Tonight: Consistent — SE winds near 10 knots, increasing to 10 to 15 knots overnight. A slight chance of showers as the boundary layer moisture ticks up.
• Sunday: No change — SE 10-15 knots, 1-2 ft reef, around 2 ft offshore. The ridge still holds through Sunday.
• Monday: Still showing variable winds 5-10 knots with a slight chance of showers. Lingering frontal boundary mentioned in the synopsis.
• Gulf Stream position: New NOAA update as of May 5 — still showing 10 NM SE of Alligator Reef, 8 NM SE of Molasses Reef for Islamorada/Key Largo. Steady stream position. New detail added for Sand Key (12 NM south) and Cosgrove Shoal (13 NM south) — the stream sits tight against the entire Keys chain.

What it means for the rest of Saturday

The midday update is a positive signal. The morning forecast anticipated a building breeze pushing toward 15 knots through the afternoon, but the actual gradient is running 5 to 10 knots — noticeably lighter. That changes the calculus for the afternoon window.

Updated Captain’s Take (Midday):

1. The 4:16 PM incoming tide just got a green light. With winds running 5-10 knots instead of 10-15, the afternoon bite window is more comfortable and the fish are less likely to be spooked by chop. The incoming pushes clean water onto the reef face.
2. Offshore in the afternoon is more doable than the morning forecast suggested. Seas holding around 2 feet, wind lighter, riding conditions better. The 10-mile run to the Alligator stream edge is a legitimate afternoon option.
3. The midday lull is still real (low tide at 11:00 AM at 0.3 ft), but the afternoon pickup arrives with lighter wind than expected — which means cleaner water on the reef face when the tide turns.
4. Sunday remains similar to what Sunday was always going to be — SE 10-15 knots, fishable. But if today’s breeze stays in the 5-10 knot range longer, Sunday morning might also start lighter before the gradient tightens.
5. No rain concern — the dry ridge is locked in. A slight chance of showers overnight is the only mention, and that’s minimal.

Bottom line

The morning was conservative on wind speed, and the actual day is running 5 knots lighter than the early forecast anticipated. That’s a win for anglers. The afternoon incoming tide at 4:16 PM sets up better than this morning’s forecast suggested. Get out there, work the 4:16 PM incoming window, and enjoy a Saturday that’s a little more comfortable than the alarm clock predicted.

NOAA 10:52 AM EDT midday update confirms: winds running lighter than forecast, seas holding at 2 feet not building to 3, ridge locked in through Sunday. The afternoon window is the call.

Evening Addendum — 5:00 PM EDT (based on NOAA 4:33 PM EDT update)

Fresh source: National Weather Service Key West coastal waters forecast, issued 4:33 PM EDT Saturday, May 9, 2026. The final evening confirmation is in, and it caps off a day that ran gentler than the morning alarm suggested.

What’s materialized since midday

• Wind — confirmed lighter: The midday read had SE winds at 5-10 knots. The 4:33 PM evening forecast says Southeast to south winds near 10 knots for tonight. The gradient tightened slightly through the afternoon as expected, but never hit the 15-knot range the morning forecast warned about. Gentle to moderate was the story, exactly.
• Hawk Channel seas: 1 to 2 feet — held all day. The 4:16 PM incoming tide pushed through clean water with manageable chop. Comfortable afternoon.
• Straits of Florida offshore: Southeast to south winds 10 to 15 knots, seas 2 to 3 feet. Wave detail: East to southeast 2 feet at 4 seconds — short-period wind wave, no long-period swell mixing in. The 3-foot number finally showed up in the offshore evening zone, but only at the end of the day when boats are back at the dock.
• Florida Bay: SE winds near 10 knots, smooth to a light chop — fishable all afternoon.
• Synopsis holding: High pressure over the western Atlantic dominating. Gentle to moderate breezes through the weekend. Light to gentle breezes with variable winds by start of work week. Deep dry layer keeping rain and thunder chances low.
• Gulf Stream position (May 5 update repeated) — confirmed no change. Stream still 10 NM off Alligator, 8 NM off Molasses.

How the day played out

The midday call was right: this was a lighter day than the 4:17 AM forecast painted. SE winds ran 5-10 knots for most of the afternoon, only bumping toward 10 knots in the evening. The 4:16 PM incoming tide fired up a solid late-afternoon bite on the reef. Hawk Channel stayed at 1-2 feet — comfortable reef fishing conditions.

The midday forecast’s suggestion that the offshore run was more doable than originally thought held up. The 10-mile run to the Gulf Stream edge was manageable for boats that timed it right.

Tonight’s setup

• Southeast to south winds near 10 knots — settling overnight
• Hawk Channel: Seas 1 to 2 feet, a light chop
• Straits offshore: Seas 2 to 3 feet — the 3-foot number appears tonight as the evening breeze kicks up
• A slight chance of showers develops — the first moisture mention since the ridge locked in
• Wave detail: East to southeast 2 feet at 4 seconds — purely wind-driven

Tomorrow’s outlook (Sunday, May 10)

This is where the 4:33 PM update matters most. Here’s the freshest Sunday read:

Hawk Channel:

• Southeast winds near 10 knots, seas 1 to 2 feet, nearshore waters a light chop
• A slight chance of showers and thunderstorms — the first thunder mention in days. The dry ridge is still dominant but the boundary layer moisture is starting to creep in

Sunday Night:

• East to southeast winds near 10 knots, increasing to 10 to 15 knots — the gradient tightens Sunday evening
• Seas 1 to 2 feet, building to around 2 feet
• Light chop becoming a light to moderate chop
• Slight chance of showers and thunderstorms continues

Offshore Straits (Sunday):

• East to southeast winds 10 to 15 knots, decreasing to near 10 knots — morning breeze peaks early then settles
• Seas around 2 feet. Wave detail: East to southeast 2 feet at 5 seconds — slightly longer period than today, which suggests a cleaner sea state
• Slight chance of showers and thunderstorms

Florida Bay (Sunday):

• Southeast winds near 10 knots, a light chop, around 1-foot seas
• Slight chance of showers and thunderstorms

Key differences from today:

1. Slightly more organized wind direction — east to southeast vs today’s southeast to south. This means the drift is more east-to-west along the reef axis, which is better for chumming slick management
2. Waves pick up period by 1 second (4s → 5s) — not a huge jump but indicates a more developed sea state vs today’s building chop
3. Rain/thunder mention returns — slight chance (20%), not a washout, but the first time in days. The deep dry layer isn’t gone, but moisture is filtering in
4. Sunday night gradient tightens — the 10-15 knot window returns Sunday evening, so the afternoon window is the play, not the evening

Extended week ahead (updated with 4:33 PM data)

Day	Wind	Seas	Rain	Vibe
Sunday	SE 10 kts	1-2 ft reef / ~2 ft offshore	Slight chance T-storms	Fishable morning, building evening
Monday	SE 10-15 → SE 5-10 kts	~2 ft → 1-2 ft	Slight chance showers	Softer late, variable shift
Tuesday	Variable ~5 kts	~1 ft	Chance showers	Flat calm, unsettled
Wednesday	NE→E ~5 kts var	1 ft or less	Slight chance T-storms	Post-front lull
Thursday	N→NE ~5 kts	1 ft or less	Slight chance showers	Clean but cool-ish breeze

Sunday is the play if you couldn’t make it out today. Monday brings a subtle pattern shift. Tuesday-Wednesday is the flat-calm window but with increasing shower chances as a frontal boundary lingers over South Florida.

Sunday Captain’s Call

1. Go early, wrap by early afternoon. Sunday morning is the money window — SE 10 knots, 1-2 feet, organized east-to-southeast drift. The bite on the incoming tide (low at 11:47 PM Saturday night, high at 5:51 AM Sunday, then falling through the day) means the morning outgoing is the best window.
2. Sunday afternoon is a shorter window than today. The gradient tightens toward 10-15 knots by evening. The afternoon incoming (5:45 PM Sunday high) is real but may come with building breeze. If you’re offshore, be back at the reef before the 3:00 PM wind bump.
3. The reef is still the call Sunday. Same play as today — anchor upwind, chum the slick, work the structure in 40-60 feet. Hawk Channel at 1-2 feet is a carbon copy of today’s conditions.
4. Keep an eye on the sky. The slight chance of thunderstorms is the first mention in days. It’s low confidence (20% at most) but Saturday showed drier conditions than forecast, and Sunday could flip wetter.
5. Monday is the pivot day. Variable winds and a chance of showers. The settled ridge that’s dominated this week starts to crack. If you’re planning Monday, stay flexible.
6. Tuesday through Thursday looks flat. Post-front, light variable winds, seas 1 foot or less. This is the backcountry / nearshore window. The offshore run may be glass but scattered showers are possible every day.

Bottom line

Saturday delivered exactly what the midday forecast promised — a lighter, more comfortable day than the 4:17 AM alarm suggested. The ridge held, the breeze stayed manageable, and the afternoon incoming tide at 4:16 PM gave anglers a solid closing window.

Sunday is a carbon copy with a tighter evening cap. Monday is the first real pattern change in a week. Tuesday through Thursday is flat but unsettled.

The spring ridge is fading, but it’s not done yet. One more good day Sunday. Then we watch the front.
