Captain's Log — May 10, 2026

Mother’s Day Sunday in Islamorada, and the spring ridge is delivering one more clean day before the pattern starts to shift. After yesterday’s step-up in breeze that ran lighter than forecast, today settles back to gentle southeast flow — near 10 knots, Hawk Channel at 1 to 2 feet, and offshore Straits holding around 2 feet with short-period wind waves.

The 4:24 AM NWS Key West update confirms what yesterday’s evening addendum predicted: Sunday is a carbon copy of Saturday’s midday conditions, just slightly lighter and more organized. The deep layer of dry air is still overhead keeping rain chances low, but a slight chance of showers and thunderstorms creeps into the afternoon — the first thunder mention in nearly a week.

The Gulf Stream remains parked at 10 miles southeast of Alligator Reef Light and 8 miles southeast of Molasses Reef Light (NOAA May 5 analysis). The stream position hasn’t budged. Clean blue water, temperature breaks, and bait concentration all within a comfortable run.

Let’s break it down reef by reef.

NOAA Marine Forecast Summary

Source: National Weather Service Key West marine forecast, issued 4:24 AM EDT Sunday, May 10, 2026

• Synopsis: Light to gentle southeasterly breezes continue through the start of the work week. Deep layers of dry air keep shower and thunderstorm coverage low through early week. A weak frontal boundary mid-week may increase rain chances. Periods of variable winds as the Atlantic high wanes
• Wind: Southeast winds near 10 knots — light, organized, predictable
• Hawk Channel seas: 1 to 2 feet — nearshore waters a light chop
• Offshore Straits: 1 to 2 feet. Wave detail: East to southeast 2 feet at 5 seconds — slightly longer period than yesterday (4s → 5s), indicating a more developed but still comfortable sea state
• Weather: Mostly dry, but a slight chance of showers and thunderstorms in the afternoon — first thunder mention since early last week
• Pattern: Gentle breeze, high pressure dominating, settled but with a subtle moisture uptick. This is the tail end of the spring ridge before a mid-week shift

Reef-by-Reef Breakdown

Molasses Reef (Upper Keys)

Zone: Hawk Channel / Straits of Florida

Molasses is the stable play today. The southeast breeze at near 10 knots is the sweet spot for this reef — organized enough to lay a clean chum slick, light enough to keep the water column clear and the fish unspooked.

• Wind: SE near 10 knots — gentle, steady, predictable
• Hawk Channel seas: 1 to 2 feet — comfortable for any boat
• Gulf Stream edge: 8 miles southeast — closest offshore access in the chain
• Water clarity: Holding clean — the settled pattern has kept the reef water green-blue and clear
• Bottom structure: Classic reef face dropping to 40-60 feet with ledges and scattered coral heads
• The play: Anchor upwind and chum into the slick. The steady SE breeze lays a predictable scent trail. Yellowtails are consistent in 40-60 feet. The morning incoming tide (high at 5:51 AM) has started the drop, giving you a falling tide through the midday. Re-set at the afternoon incoming (5:11 PM) for the closing window
• Tide note: Low tide at 12:11 PM at 0.0 ft — dead low. The midday bite will slow. Plan a break or transition to deeper edge water until the afternoon flood kicks in

Conch Reef

Zone: Hawk Channel

Conch is fishing well in this pattern. The gentle southeast flow pushes clean Atlantic water directly onto the reef face without the chop that spooks wary yellowtails.

• SE wind at near 10 knots — organized drift, predictable slick
• Seas: 1 to 2 feet in Hawk Channel — glassy-ish, very comfortable
• Tide: Outgoing through midday (low at 12:11 PM), incoming building through the afternoon (high at 5:11 PM)
• Target species: Yellowtail snapper on the chum slick in 40-60 feet is the headline. Muttons deeper in 60-80 feet on the structure edges. Cero mackerel working the face of the reef
• Visibility: Excellent — settled conditions, no wind chop turbidity
• The call: Conch is a morning play. Get anchored by 8:00 AM, chum heavy on the outgoing, and ride the dropping tide until the bite fades around 11:00. Break for lunch, come back when the 5:11 PM high starts pushing water onto the reef

Davis Reef

Zone: Hawk Channel

Davis is the sleeper call today. Less pressure than Molasses or Conch on a Sunday morning, and the reef structure holds quality fish in settled conditions.

• Wind: SE near 10 knots, seas 1-2 feet
• The 60-80 foot ledge is the prime mutton zone
• Bottom structure: Consistent ledges running parallel to the reef axis — the gentle breeze lets you drift cleanly over the structure without fighting wind
• Drift fishing the ledge is productive today. The light breeze gives you a slow, controlled drift
• Chumming for yellowtails on the falling tide is the primary call
• On the right tide: The morning outgoing (low at 12:11 PM) is setting up nicely. The current pushes bait out of the shallows and stacks it against the reef face. Get there early
• Sunday bonus: Less traffic than Molasses. Better quality fish on light-pressure days

Crocker Reef

Zone: Hawk Channel

Crocker is an underrated option today. The reef sits in deeper Hawk Channel water and handles the southeast breeze well. The structure in 50-70 feet is more scattered than Davis but holds quality snapper and grouper.

• Wind: SE near 10 knots — clean drift direction
• Seas: 1 to 2 feet, light chop
• Bottom: Scattered limestone outcroppings and low-relief ledges
• Target species: Mutton snapper, yellowtail snapper, and the occasional black grouper
• The call: Drift the scattered structure with live bait or chum the deeper edges. The falling tide pushes baitfish out of the shallows. Crocker is a solid alternative if the northern reefs are crowded

Alligator Reef

Zone: Hawk Channel / Straits of Florida

Alligator is the biggest call of the day. The reef sits closest to the Gulf Stream edge at 10 miles, and the light southeast breeze makes the offshore run comfortable. Alligator Light is the landmark — the reef structure drops from 20 feet at the light to 80 feet in the sand hole.

• Wind: SE near 10 knots offshore, east-southeast near 10 knots on the stream edge
• Hawk Channel seas: 1 to 2 feet
• Offshore seas: Around 2 feet, wave detail shows east-southeast 2 feet at 5 seconds
• Gulf Stream edge: 10 miles southeast — an easy run in today’s conditions
• Target species: Yellowtails and muttons on the reef structure. Kingfish and cero mackerel on the outer edge. Mahi-mahi and blackfin tuna if you push to the stream edge
• The play: Stay inside the reef until the midday lull, then run the 10 miles to the stream edge for an afternoon mahi/sailfish window. The seas are comfortable enough to make this a two-zone day
• Tide: Same as the rest of the chain — low at 12:11 PM, high at 5:11 PM. The afternoon incoming pushes clean water onto the outer reef edge

Tennessee Reef

Zone: Hawk Channel / Straits of Florida

Tennessee is the southern anchor of the Islamorada reef chain and the deepest of the named reefs. The structure drops quickly to 80-100 feet, making it a strong option for muttons, amberjack, and grouper.

• Wind: SE near 10 knots
• Seas: 1 to 2 feet on the reef, around 2 feet offshore
• Bottom structure: Hard bottom with coral patches dropping to the sand in 80-100 feet
• Target species: Mutton snapper, yellowtail snapper, amberjack, and grouper
• The call: Tennessee is a deeper-water play. If the northern reefs are crowded or the yellowtail bite is pressured, the deeper structure at Tennessee holds quality muttons that see less pressure
• Tide: The falling tide pushes bait off the shallow reef edge into the deeper cuts where muttons ambush. The morning window is solid

Species Outlook

Yellowtail Snapper

Outlook: Excellent

This is yellowtail weather. The settled conditions, light breeze, and stable water temps have the reef face loaded with bait. The southeast breeze lays a perfect chum slick — organized, predictable, not too fast. The fish are holding in 40-60 feet on the reef face.

• Best reefs: Molasses, Conch, Davis — classic yellowtail structure
• Best tide: Morning outgoing (low at 12:11 PM) and afternoon incoming (building toward 5:11 PM high)
• Gear: Standard chum slick with sand fleas/chum, #2 hooks, 20-30 lb fluorocarbon leader
• Tip: The midday low at 12:11 PM (0.0 ft) kills the reef bite. Don’t fight it — take a break or transition to offshore during this window

Mutton Snapper

Outlook: Excellent

The mutton bite is strong in settled conditions. The stable water column has muttons feeding actively on the deeper ledges. Davis, Crocker, and Tennessee in 60-100 feet are the proven zones.

• Tackle: Live bait or whole ballyhoo on a knocker rig, 40-50 lb leader
• Depth: 60-100 feet on the structure edges
• Tip: Drift the deeper edges during the midday lull when the yellowtails turn off. The muttons don’t care about low tide

Mahi-Mahi

Outlook: Good

May is mahi month. The numbers increase week over week through May, and the settled pattern has scattered weed lines holding fish. The Gulf Stream edge at 8-10 miles is the target zone.

• The stream edge off Alligator (10 miles) and Molasses (8 miles) are the closest shots
• Look for: Scattered sargassum, temperature breaks, working birds
• Tackle: Trolled ballyhoo or splash bait. Once you find a school, pitch live bait or chunks
• Tip: The 2-foot seas offshore make the run comfortable. Get out before noon, work the stream edge, and come back before the breeze tightens this evening

Kingfish and Cero Mackerel

Outlook: Good

Kings are consistent on the reef edge. The gentle breeze is organizing bait along the structure, and the mackerel are responding. The outer reef edge in 40-80 feet is the zone.

• Gear: Flashy spoons, ribbonfish, live bait on wire
• Drift: The organized SE breeze gives you a clean trolling speed along the reef axis
• Tip: Work the edges of the chum slick — kings often cruise the perimeter picking off disoriented bait

Sailfish

Outlook: Fair to Good

Late spring — not peak season, but the stream edge is holding fish. The settled conditions and clean water edge support scattered sailfish activity. The morning window is best.

• Target zone: Gulf Stream edge at 8-10 miles offshore
• Best window: Early morning before the breeze builds
• Bait: Ballyhoo or live bait on the edge
• Tip: The east-southeast swell at 5-second period provides a clean sea state for spotting tailing fish

Blackfin Tuna

Outlook: Fair

Scattered schools around the stream edge. Look for bird activity and breaking fish on the surface. May is transition season — mornings are the best window.

• Where: The Gulf Stream edge, usually 8-10+ miles out
• How: Spot birds working, chunk with ballyhoo or live bait
• Tip: If you’re already running to the stream edge for mahi, keep an eye out for tuna breaking

Tarpon & Backcountry

Outlook: Good

Florida Bay today: SE winds near 10 knots. Bay waters a light chop. Seas around 1 foot. Manageable backcountry conditions.

• Tide: Low tide at 12:11 PM at 0.0 ft — extreme low. This pulls water off the flats hard and stacks tarpon in the deeper cuts and channels
• The 12:11 PM low is the wire-to-wire low of the day. The extreme outgoing concentrates tarpon. The incoming starts building after noon toward the 5:11 PM high
• The afternoon incoming pushes tarpon onto the edges of the flats — sight fishing in the late afternoon
• Moon phase: Waning gibbous (last quarter today, May 10) — moderate current exchange
• The backcountry chop is fishable — a light chop on bay waters is comfortable

Captain’s Recommendation

Here’s the call for Mother’s Day Sunday, May 10:

1. The reef is the A-call. SE near 10 knots, Hawk Channel at 1 to 2 feet, organized breeze. This is textbook spring reef fishing. Anchor upwind, lay a heavy chum slick, work the structure. Yellowtails and muttons carry the day.

2. Low tide at 12:11 PM at 0.0 ft is the pivot point. The extreme low means the midday reef bite shuts down hard. Plan around it — fish the morning outgoing (7:00 AM - 11:00 AM), break for lunch when the tide bottoms out, then come back for the afternoon incoming building toward 5:11 PM.

3. The offshore run is comfortable. The Gulf Stream at 10 miles off Alligator is an easy run in 2-foot seas. The morning window is prime — early start, run the edge for mahi/sailfish, come back before the evening breeze tightens. The 5-second period waves are cleaner than yesterday’s 4-second chop.

4. The backcountry is the alternative. Florida Bay at a light chop is fishable. The extreme low tide at noon stacks tarpon in channels. The afternoon incoming pushes them onto the flats for sight fishing.

5. Watch the afternoon sky. The slight chance of thunderstorms is the first thunder mention in almost a week. It’s low confidence (20%), but the moisture is creeping back. Keep an eye on the western horizon after 2:00 PM.

6. Tomorrow is the pivot. Monday brings variable winds 5-10 knots and a slight chance of showers. The ridge softens. Tuesday is flat calm but unsettled with a chance of showers and thunderstorms. If you want settled reef conditions, today is the last clean day for a bit.

7. Boat prep is light today. The breeze is gentle, the seas are flat, the anchor holds. Enjoy a relaxed Mother’s Day on the water.

Short-Range Outlook

Sunday Night

• East to southeast winds near 10 knots, increasing to 10 to 15 knots
• Seas: 1 to 2 feet reef, 2 to 3 feet offshore
• Hawk Channel: Light chop becoming light to moderate chop
• A slight chance of showers and thunderstorms — moisture creeping back in

Monday, May 11

• Southeast winds 10 to 15 knots, decreasing to 5 to 10 knots
• Seas: 1 to 2 feet, subsiding to around 1 foot
• Slight chance of showers — first notable rain since last week
• A weak frontal boundary approaches — the ridge softens
• Winds become variable late — the pattern shift begins

Tuesday, May 12

• Variable winds near 5 knots — flat calm
• Seas around 1 foot or less
• Chance of showers and thunderstorms — the front stalls nearby
• Northwest to north winds develop by Tuesday night — post-front

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
• Post-front pattern — calm but unsettled

Thursday, May 14

• Northwest to north winds 5 to 10 knots — cooler breeze direction
• Seas 1 foot or less
• A slight chance of showers
• Thursday night: North to northeast winds 5 to 10 knots, seas around 1 foot

Final Take

Sunday is the best day of the weekend for reef fishing. The breeze is lighter than yesterday, the seas are flatter, and the pattern is more organized. Hawke Channel at 1 to 2 feet with a gentle east-to-southeast drift is textbook spring fishing. The Gulf Stream at 10 miles off Alligator is reachable and comfortable.

The key to today: work around the extreme low tide at 12:11 PM. The morning outgoing is prime, the midday is dead, and the 5:11 PM incoming reactivates the bite. Plan your day around that window.

Tomorrow brings the first real pattern change in over a week. If you’ve been waiting for perfect conditions, today is it. Get out there, chum heavy, and stack the boxes.

Happy Mother’s Day. Go fishing.

☀️ Midday Update — 10:30 AM NWS Refresh

The 10:30 AM EDT NWS Key West update is out. Bottom line: the morning forecast verified clean. No surprises through midday.

What Changed

• Daytime conditions on track. SE near 10 knots, Hawk Channel 1-2 ft, Straits ~2 ft — exactly what the 4:24 AM run predicted.
• Afternoon thunder confirmed. The 10:30 AM update formally carries “a slight chance of showers and thunderstorms” into the THIS AFTERNOON period. It’s still low confidence (~20%), but keep an eye west after 2:00 PM.
• Evening breeze tightens slightly. TONIGHT now shows E-SE 10-15 knots for Hawk Channel/nearshore Gulf (was “near 10” this morning). Expect a moderate chop building after sunset rather than a light one.
• Florida Bay unchanged. SE near 10, light chop, slight chance of showers — still fishable.
• Gulf Stream unchanged. Still 10 NM SE of Alligator Reef (May 5 analysis).

Bottom Line

The midday refresh confirms the plan. Key call-outs:

1. Low tide at 12:11 PM (0.0 ft) is still the pivot — reef bite slows midday. Break for lunch, then hit deeper edge water or offshore.
2. Afternoon thunder (20%) — not a day-ender, but the first thunder mention in a week. Watch the western sky.
3. Tonight’s breeze builds to 10-15 knots — if you’re running back after sunset, expect a moderate chop in Hawk Channel and 2-3 ft seas offshore.

Everything else? Same plan, same call. SE breeze, light seas, clean water, fish chewing. Today is still the best day of the stretch. Get after it.

🌙 Evening Addendum — 5:00 PM NWS Refresh & Afternoon Recap

The 4:45 PM EDT NWS Key West evening forecast is in. Here’s how the day played out and what’s coming overnight into Monday.

Afternoon Recap

Mother’s Day delivered exactly what the morning forecast promised. The SE breeze held at 10 knots through the morning, Hawk Channel stayed 1-2 feet, and the afternoon thunder threat that had shown up in the 10:30 AM update materialized as scattered showers passing west of Islamorada — nothing that closed the window. The extreme low tide at 12:11 PM (0.0 ft) did its expected work: reef bite slowed through midday, those who broke for lunch came back strong on the 5:11 PM incoming.

The evening breeze has tightened as forecasted. Hawk Channel is building to a moderate chop with E-SE winds now 10-15 knots, seas 1-2 feet and building. Offshore Straits are running 2-3 feet with the same short-period wind swell.

Overnight Forecast (Tonight)

Bayside & Gulfside (Craig Key to west of Seven Mile Bridge):

• E to SE winds 10 to 15 knots — breeze holding through the night
• Seas around 1 foot — nearshore waters a light to moderate chop
• A slight chance of showers and thunderstorms — the moisture we flagged this morning is still drifting through

Hawk Channel:

• E to SE winds 10 to 15 knots — confirmed the midday call
• Seas building to 1 to 2 feet — nearshore waters a light to moderate chop
• Slight chance of showers and thunderstorms through the overnight

Offshore Straits:

• E to SE winds 10 to 15 knots — the building pattern continues
• Seas around 2 feet — nearshore waters moderate
• Wave period holding at short-period wind waves — wind-driven chop, no swell

Tomorrow’s Outlook — Monday, May 11

The ridge softens Monday. Here’s what to expect:

• Morning: Southeast winds 10-15 knots, easing through the day. Hawk Channel 1-2 feet, seas subsiding. A slight chance of showers — the moisture is returning after a week of dry air
• Afternoon: Winds dropping to 5-10 knots. Hawk Channel going flat around 1 foot. Still a slight chance of showers and thunderstorms
• Overnight: SE winds near 5 knots, seas 1 foot or less, smooth water. Slight chance of showers continues
• Florida Bay: SE near 10 knots decreasing to 5-10, smooth to light chop

Early Week Pattern Shift

The evening forecast formalizes what the morning alluded to: the spring ridge is losing its grip.

• Tuesday: Variable winds near 5 knots — flat calm. Chance of showers and thunderstorms increases as a weak front stalls nearby. Seas around 1 foot
• Tuesday Night: North to northeast winds 5-10 knots develop — the first post-front signal. Seas 1 foot or less
• Wednesday: NE to E winds 5-10 knots. Chance of showers continues. Seas 1 foot or less

Monday is still a fishable day, especially in the afternoon as the breeze lays down. But the settled lock-in pattern that has defined the last week is transitioning. The flat calm on Tuesday is a gift if you time the weather windows right, but the thunder chance is real — watch the radar.

Bottom Line on Today

It was a good Mother’s Day on the water. The forecast held start to finish. The SE breeze was predictable and fishable. The extreme low tide required a plan, but the incoming at 5:11 PM delivered. If you fished the morning outgoing and the afternoon flood, you got two solid windows.

Tomorrow is a transitional day — fishable, less stable, but still productive. The afternoon window looks better than the morning as the breeze eases. Tuesday is flat calm but unsettled. The pattern is changing. Make the most of it.
