Captain's Log — May 11, 2026

Southeasterly breezes have slackened today as a weak frontal boundary slides into the northern Gulf. The result is about as benign as it gets for mid-May: light variable winds, flat seas, and dry air overhead keeping shower chances minimal. The front is positioned far enough north that its primary impact on the Keys is dialing back the typical spring southeasterly gradient rather than bringing any weather.

NOAA Marine Forecast Summary

Source: National Weather Service Key West coastal waters forecast, issued 4:27 PM EDT Monday, May 11, 2026

• Synopsis: Southeasterly breezes have slackened due to a weak frontal boundary moving into the northern Gulf. Dry layers of air above the surface will keep shower chances low through tonight. The front may pull a plume of moisture and increased rain chances as early as Tuesday. High confidence that breezes will remain light throughout the week with periods of variable winds.
• Wind: East 5 to 10 knots in Hawk Channel tonight, variable near 5 knots on Tuesday. The pattern is characterized by periods of variable winds — a week of light breezes, shifting directions as weak boundaries and sea breeze circulations dominate.
• Hawk Channel seas: Around 1 foot — flat and fishable
• Offshore Straits: 1 to 2 feet tonight and Tuesday. Wave detail: East 2 feet at 4 seconds — short-period wind chop only, no ground swell
• Weather: A slight chance of showers and thunderstorms tonight, increasing to a chance on Tuesday as the frontal moisture plume arrives
• Pattern: Light breezes all week. High confidence that winds stay below 10 knots through the entire forecast period. Variable directions dominate — expect east-southeast through Tuesday, shifting north-northeast by Tuesday night, then cycling through northwest before settling back east-southeast by the weekend.

Gulf Stream Position

NOAA’s latest shoreward edge report, as of May 5:

• 10 NM southeast of Alligator Reef Light (off Islamorada) — cleanest offshore launch for mid-island
• 8 NM southeast of Molasses Reef Light (off Key Largo) — shortest run on the upper Keys line
• 7 NM southeast of Carysfort Reef Light (off Ocean Reef)
• 14 NM south of Looe Key (off Big Pine)
• 14 NM southeast of Sombrero Key (off Marathon)
• 12 NM south of Sand Key Light (off Key West)
• 23 NM south of Dry Tortugas Light on Loggerhead Key

The stream has pulled slightly closer to Molasses (8 miles vs 6 in the previous report) and Carysfort (7 miles) — a subtle inshore nudge that puts cleaner water within easy reach from the upper Keys.

Reef Conditions, Islamorada Line

Conditions across the reef tract are about as uniform as they get: 1-foot seas, light variable wind, smooth nearshore waters. There’s no gradient to worry about — every reef from Molasses down to Tennessee is flat and accessible.

Molasses Reef

• East winds 5 to 10 knots tonight, variable near 5 knots Tuesday
• Seas around 1 foot — textbook flat
• Gulf Stream edge roughly 8 miles southeast — slightly closer than last week
• A slight chance of showers tonight, increasing Tuesday
• The short-period east chop (2 ft at 4 seconds offshore) doesn’t reach inside the reef line. Hawk Channel is genuinely smooth

Conch Reef

• Clean structure, consistent yellowtail bottom through summer
• Light wind creates a lazy drift perfect for chum slick establishment
• Tuesday’s moisture plume may bring isolated showers, but the dry air today kept everything clear
• Transitioning from the east breeze tonight to variable winds Tuesday means morning will be super calm

Davis Reef

• Mid-reef anchor in flat conditions. 1-foot seas, smooth nearshore water
• Mutton drifts in 60-80 feet on the tide change
• The variable wind pattern for Tuesday means you’ll want to anchor or set a tight drift early
• Fish the bottom structure — yellowtails and muttons both holding on the hard bottom

Crocker Reef

• Light wind, flat seas, clean water — the low-energy pattern makes for ideal conditions
• Yellowtail slick fishing is the proven play
• Cobia patrol the edges this time of year — keep a pitch bait ready
• The dry air mass overhead today means excellent visibility in the water column

Alligator Reef

• Gulf Stream edge at 10 miles southeast — consistent offshore access for mid-island captains
• Hawk Channel conditions are flat through the forecast period
• Alligator is the preferred split-day option: reef in the morning, color change run in the afternoon
• Light variable winds Tuesday mean the offshore run stays comfortable

Tennessee Reef

• Mid-Keys position, same 1-foot seas, same positive conditions
• Clean bottom structure in 50-70 feet cooks snapper consistently
• Less boat traffic than the upper Keys reefs midweek
• With this week’s light wind pattern, Tennessee sees zero weather disadvantage

Tides & Water

Tides, Islamorada (Upper Matecumbe Key, Florida Bay)

• Low: 1:52 AM at 0.3 ft
• High: 7:07 AM at 1.4 ft — morning incoming, best bite window
• Low: 2:06 PM at 0.6 ft — midday slack
• High: 6:58 PM at 1.6 ft — evening incoming, solid afternoon push

The 7:07 AM high tide is the golden window — morning incoming on flat seas. The 6:58 PM high sets up a productive evening bite for anyone staying late.

Water Temperature

• Current Islamorada reading: Approx 78-80°F nearshore
• Reef temperature: Running 80-83°F — prime spring numbers, fish metabolism in high gear
• Gulf Stream: Carrying mid-80s water in the blue — 83-85°F
• Bait activity is strong, bait balls are forming along the reef edge
• The consistent warm water means the summer pattern is essentially locked in

Moon Phase

• Waning Crescent — last quarter was May 6, new moon coming May 16
• Tide range is building toward the new moon: today’s swing is moderate (0.3 ft to 1.6 ft)
• The building tides through the week mean increasing water movement daily
• Fish the tide changes aggressively — the morning and evening incoming pushes both produce

Species Outlook

Yellowtail Snapper

• Outlook: Good
• Flat seas + light wind = textbook yellowtail conditions
• Chum slick in 40-60 feet on the morning incoming tide
• Water clarity is excellent with the dry air mass overhead reducing surface haze
• The week’s light wind pattern keeps the bottom undisturbed

Mutton Snapper

• Outlook: Good
• Davis and Crocker in 60-80 feet hold honest mutton numbers
• Live bait on structure during tide changes produces the bigger fish
• The variable wind pattern Tuesday is manageable at these sea states
• Stick to the reef edge drops for the best mutton ground

Mahi-Mahi

• Outlook: Fair
• Gulf Stream edge reachable at 10 miles off Alligator, 8 miles off Molasses
• Offshore Straits at 1 to 2 feet — about as comfortable as offshore gets
• The weak front passing north may have created some weed line action at the boundaries
• Not a peak mahi bite, but the comfortable conditions make the look worthwhile
• Keep an eye on the color change — clean Gulf Stream water is holding bait

Kingfish and Cero

• Outlook: Good
• The reef edge and current lanes are active with bait concentrations
• Kings are patrolling the drop-offs consistently
• Cero mackerel are thick on the reef — flashy spoons and ribbonfish are getting eaten
• The calm conditions make trolling the reef edge a comfortable play

Sailfish

• Outlook: Low to fair
• Dead period between spawn cycles, but clean water at the Gulf Stream edge always holds a few
• Not the time to target sails, but a sunrise bait-and-wait pass at the color change can surprise you
• Better sail odds on the May full moon cycle later this month

Tuna (Blackfin)

• Outlook: Fair
• Light wind and flat seas improve your odds of spotting surface activity
• No major bait schools reported at the humps, but conditions are good enough to make the run worth it
• Early morning at the color change or humps is your best bet
• 1-2 foot offshore seas make the run to deeper water totally painless

Tarpon and Backcountry

• Outlook: Good
• Florida Bay tonight: variable winds near 5 knots, bay waters smooth
• Tuesday: east to southeast winds near 5 knots, bay waters smooth
• The evening incoming at 6:58 PM pushes water onto the flats, pulling tarpon into channels and cuts
• Protected water is a clean alternative if you want to escape what little breeze there is
• Sight fishing in the bay is as good as it gets in these conditions
• The smooth bay continues through the entire forecast period

Grouper

• Outlook: Good
• Light wind and flat seas make deep dropping a real option
• Reef edge structure in 80-120 feet holds gags and reds
• The calm conditions let you work structure precisely without drift anxiety
• Catch-and-release the big spawners, keep a legal red or two for dinner

Captain’s Recommendation

If I’m calling it tonight looking back at the day and ahead to tomorrow:

1. Today was a sleeper — the “slackened southeast breezes” NOAA mentioned delivered glassy conditions. Anyone who got on the water had flat seas, light wind, and clear skies most of the day.
2. Tuesday is a carbon copy with more rain chance — same light winds (variable 5 knots), same flat seas (1 foot), but with a chance of showers as the front’s moisture plume slides over. Don’t let the rain chance scare you — it’s isolated, fast-moving stuff.
3. The morning incoming tide (7:07 AM → peak, fishing before it) is your best bite window — yellowtails and muttons on the reef during that incoming push
4. Offshore is comfortable — 1 to 2 feet in the Straits, Gulf Stream reachable at 8-10 miles. Make the run if you want to check the color change
5. Backcountry is also a strong play — Florida Bay is smooth, tarpon are in the channels
6. The whole week is light — NOAA has high confidence breezes stay below 10 knots through Saturday. This is a full week of fishable conditions.

Short-Range Outlook

Tonight

• East winds 5 to 10 knots in Hawk Channel. Seas around 1 foot. A slight chance of showers and thunderstorms
• Offshore: East to southeast 5 to 10 knots, seas 1 to 2 feet. Wave detail: east 2 feet at 4 seconds

Tuesday, May 12

• Variable winds near 5 knots all zones — Hawk Channel around 1 foot, offshore 1 to 2 feet
• A chance of showers with a slight chance of thunderstorms — the front’s moisture plume arrives
• Wave detail: east 1 foot at 4 seconds — minimal
• This is the day the rain chance ticks up, but the sea state doesn’t change. Still fishable

Tuesday Night

• North to northeast winds 5 to 10 knots — shift coming through after the front passes
• Seas around 1 foot across the board
• A chance of showers with a slight chance of thunderstorms

Wednesday, May 14

• Northeast to east winds near 5 knots in Hawk Channel — another light day
• A slight chance of showers and thunderstorms
• Seas: 1 foot or less near the reef, around 1 foot offshore
• Variable directions, but never strong. April showers bring May flowers, May breezes bring flat seas

Thursday, May 15

• Northwest winds near 5 knots — another direction shift but same light speed
• Seas 1 foot or less. Still flat, still fishable
• A slight chance of showers and thunderstorms

Friday, May 16 — New Moon

• Variable winds near 5 knots, becoming east to south
• Seas around 1 foot or less
• New moon means building tides through the weekend — the best fishing days of the pattern are Thursday through Sunday
• A slight chance of showers

Saturday, May 17

• East to southeast winds 5 to 10 knots — the gradient re-establishes
• Seas 1 foot or less nearshore, 1 to 2 feet offshore
• A slight chance of showers and thunderstorms

Final Take

Today’s forecast is the definition of an “it doesn’t get much better than this” May day. Light wind, flat seas, dry air overhead, and a week ahead that looks practically identical with only slightly higher rain chances.

The weak front that killed the southeast breeze today is far enough north that it doesn’t bring us any weather tonight — just dry air and comfortable conditions. When the moisture plume arrives Tuesday, it’s isolated showers, not a washout. And the wind stays light through the entire forecast period — NOAA has “high confidence” breezes remain below 10 knots all week.

The Gulf Stream is sitting at 8-10 miles off the reef, the water is 80+ degrees, the tide swings are building toward the new moon, and the fish are eating.

If you’re reading this at 5 PM on a Monday thinking about whether to book tomorrow — do it. Tuesday is going to look just like today: variable light wind, flat seas, and fish that want to eat. The only difference is you might dodge a quick shower. That’s not a reason to stay home.

Evening Addendum — 5:00 PM EDT

Afternoon Recap

The day played out exactly as the synopsis described — southeasterly breezes slackened, the weak front stayed north, and the Keys sat under a dome of dry air with calm seas across the entire coastal zone.

• Wind: East 5 to 10 knots through the day in Hawk Channel, as forecast. The “slackened” breezes NOAA mentioned were real — noticeably lighter than the typical May 10-15 knot southeast flow we’ve been seeing. Glassy conditions on the inside reefs.
• Hawk Channel seas: Around 1 foot all day — confirmed flat. No surprises, no wind against current issues.
• Offshore Straits: 1 to 2 feet — the short-period east chop (2 ft at 4 seconds) was the only energy out there. No ground swell, no secondary wind wave. Comfortable running conditions.
• Showers: None of significance. The slight chance of thunderstorms mentioned for later materialized? Barely. Dry air dominated.
• Weather: The dry layer above the surface that NOAA mentioned did exactly what they said — kept shower chances low through the day. By late afternoon the typical Florida sun was fully in charge.
• Fishery feedback: The morning incoming tide (7:07 AM high) was the productive window. Yellowtails on the reef were active through that incoming push. The 2:06 PM low created a midday lull, but the evening incoming (6:58 PM) was setting up for a strong late bite. Muttons on structure in 60-80 feet were steady.

Tomorrow’s Official Outlook — Tuesday, May 12

NOAA’s 4:27 PM extended forecast confirms minimal change: variable light breezes, flat seas, but with a nod to the frontal moisture plume arriving.

Zone	Wind	Seas	Rain
Florida Bay	East-southeast near 5 knots	Smooth	Chance of showers, slight chance of t-storms
Hawk Channel	Variable near 5 knots	Around 1 foot	Slight chance of showers/t-storms
Offshore Straits	Northeast-east 5-10 knots	1-2 feet	Slight chance of showers/t-storms
Bayside/Gulfside (Craig Key to 7 Mile)	Variable near 5 knots	1 foot or less	Slight chance of showers/t-storms

The headline for Tuesday: same seas, slightly higher rain chance. The front’s moisture plume arrives, but it’s not a washout — just a chance of scattered showers, likely in the morning or midday. The wind goes variable, meaning the morning could start with a light land breeze before the sea breeze takes over.

Gulf Stream edge remains at 8 miles off Molasses, 10 miles off Alligator. The Tuesday offshore run is the same distance, same comfortable 1-2 foot seas.

Captain’s Evening Take

1. Today was a clean, fishable Monday — flat seas, light wind, low rain. Anyone on the water got ideal May conditions. Nothing to complain about.
2. Tuesday is the same water, bring a rain jacket — the sea state doesn’t change. The only difference is a chance of isolated showers as the front’s trailing moisture passes over. Fishable all day, just keep an eye on the radar.
3. The Tuesday wind shift (variable early, north-northeast by night) means the afternoon might have more organized wind direction than the morning. The sea breeze will sort it out.
4. The rest of the week is wide open — northeast to east 5 knots Wednesday, northwest 5 knots Thursday, variable Friday for new moon. Flat seas and comfortable fishing conditions through at least Saturday.
5. New moon Saturday — building tides all week mean the fishing gets progressively better. The strongest bite days will be Thursday through Sunday as the tidal swing increases.

Tuesday’s Tide (May 12)

• Low: 2:33 AM (0.3 ft)
• High: 7:42 AM (1.7 ft) — morning bite window, strongest of the day
• Low: 3:12 PM (0.3 ft)
• High: 8:15 PM (1.6 ft) — evening incoming

The 7:42 AM high tide is the top target — incoming push on flat seas with light variable wind. That hour-and-a-half before and after peak high is the money window. The 8:15 PM high sets up a good evening bite for anyone doing an afternoon charter.

Final Word

This is a low-stakes week. Light wind, flat seas, manageable rain chances. The kind of week where the only question is which reef you want to fish, not whether you can get out. The Gulf Stream hasn’t wandered, the water is warm, and the tide building toward the new moon Saturday puts more water movement through the reef every day.

Go fish tomorrow. It’ll be the same as today, just with a little more moisture in the air.
