Captain's Log, May 5, 2026

The wind field is a mess this morning. A dying trough is still sloshing around the Florida Straits, so the breeze is going every direction at once. The good part is that it’s on its way out. Today is the pivot. The Atlantic Ridge builds across Florida starting Wednesday, and by midweek we should have classic late-spring Keys water: light east-southeast flow, flat seas, and fish that want to eat.

NOAA Marine Forecast Summary

Source: National Weather Service Key West marine forecast, issued 4:28 AM EDT Tuesday, May 5, 2026

• Wind: Variable near 5 knots today, becoming northwest late. Light and confused through the morning while the trough hangs on, but the direction sorts itself out by afternoon.
• Hawk Channel seas: Around 1 foot, flat by any standard
• Offshore Straits: 2 to 3 feet today, subsiding to 1 to 2 feet tonight. Wave detail: Northeast to east 2 feet at 7 seconds with a northwest to north 1 foot at 5 seconds secondary swell
• Weather: A slight chance of showers today, notably less than Monday. Isolated morning showers should end by later today
• Pattern: NOAA calls the wind field “chaotic,” and it stays that way until the Atlantic Ridge can set up across Florida on Wednesday. Once it does, we get the full spring gradient: east to southeast 5 to 10 knots, the sea state dropping to flat, and deep-layer moisture building through the week without much rain chance until Saturday

Gulf Stream position

NOAA’s latest shoreward edge report, as of April 28:

• 10 NM southeast of Alligator Reef Light (off Islamorada), the closest clean exit for mid-island
• 6 NM southeast of Molasses Reef Light (off Key Largo), the shortest run on the line
• 9 NM south of Looe Key (off Big Pine)
• 12 NM southeast of Sombrero Key (off Marathon)
• 16 NM south of Dry Tortugas Light on Loggerhead Key

The stream hasn’t shifted from last week. Alligator at 10 miles out is still the smartest offshore launch from the Islamorada line.

Reef Conditions, Islamorada Line

The reef is fishable all day in 1 foot seas. The variable wind makes drifting a little unpredictable this morning, but once the breeze settles northwest late today and east-southeast by Wednesday, everything tightens up.

Molasses Reef

• Variable winds near 5 knots early, becoming northwest late, light chop in Hawk Channel
• Seas around 1 foot, about as clean as it gets
• Gulf Stream edge roughly 6 miles southeast, shortest run for color change water
• A slight chance of showers this morning, clearing out by afternoon
• The variable wind is a non-issue at these sea states. Go fish.

Conch Reef

• Clean water over stable snapper bottom
• Any morning shower that fires should burn off by late morning
• Yellowtail chumming in 40-60 feet is the proven play today
• The light variable breeze makes for a lazy drift, which is what you want for getting the chum slick established

Davis Reef

• A mid-reef standout in flat conditions. 1-foot seas mean zero excuses
• Mutton drifts in 60-80 feet should fire on the incoming tide
• The afternoon window will be cleaner than the morning as the wind organizes
• If you want a consistent day of bottom fishing with minimal weather worry, Davis is hard to beat

Crocker Reef

• Light wind, flat seas, clean water. The variable breeze won’t mess with a drift here
• Yellowtail slick fishing is the high-percentage play
• Good structure holds muttons and the occasional cobia
• With the pattern improving through the week, Crocker only gets better from here

Alligator Reef

• Gulf Stream edge at 10 miles southeast, still the best offshore exit for mid-island captains
• Hawk Channel is flat, so the variable wind is a non-factor
• Once the ridge takes over Wednesday, the east-southeast flow pushes clean water in from the Atlantic side
• If you want a reef-and-offshore split day, Alligator puts both within easy range

Tennessee Reef

• A mid-Keys anchor point with the same 1-foot seas and the same improving trend
• Clean structure in the 50-70 foot range holds steady snapper action
• Sits far enough south along the chain that the upper Keys wind mess barely reaches it
• Consistent bottom fishing that puts meat in the box without the crowd

Tides & Water

Tides, Islamorada (Upper Matecumbe Key, Florida Bay)

• High: 1:53 AM at 0.4 ft (already past)
• Low: 7:39 AM at 0.2 ft
• High: 12:50 PM at 0.7 ft
• Low: 9:32 PM at -0.0 ft (negative low)

The 7:39 AM low gives you the morning slack window. The 12:50 PM high is the afternoon incoming push that should fire up the reef bite. The 9:32 PM negative low stacks fish hard in channels and cuts for the evening and early morning crowd.

Water temperature

• Current Islamorada reading: ~77-79°F nearshore (24-25°C observed)
• Reef temperature: Running 79-82°F, solid spring numbers
• Gulf Stream: Carrying spring heat in the 83-85°F range inside the blue water
• Virginia Key (NOAA reference): Last reliable data shows 81-82°F, so expect similar along the reef tract
• Bait is active and fish metabolism is up. The water temps are in the sweet spot for mixed bag fishing

Moon phase

• Waning Gibbous (full moon was April 30, last quarter coming May 7)
• Tide range today is modest. Not the big swings of the full moon, but the negative low at 9:32 PM (-0.0 ft) gives honest water movement for the late bite
• Fish the tide changes. The 7:39 AM low to 12:50 PM incoming is your primary window

Species Outlook

Yellowtail snapper

• Outlook: Good
• The reef is clean and calm. Morning incoming tide (7:39 AM low into the 12:50 PM high) sets up a nice chumming window
• Patient slick fishing in 40-60 feet is the proven approach
• Water clarity is decent despite the variable wind, since 1-foot seas don’t stir up the bottom

Mutton snapper

• Outlook: Good
• Davis, Crocker, and Alligator in 60-80 feet are the high-percentage plays
• The variable breeze won’t make drift fishing difficult at these sea states
• Live bait on structure in the afternoon incoming window is money

Mahi-mahi

• Outlook: Fair
• Gulf Stream edge is reachable at 10 miles off Alligator and 6 miles off Molasses
• Offshore Straits at 2 to 3 feet today is manageable for the run
• The dying trough may have scattered some weed lines, so keep your eyes peeled for sargassum, birds working, or color changes
• Wednesday through Friday is the better bet for a dedicated mahi run, once the seas settle to 1-2 feet

Kingfish and cero

• Outlook: Good
• The reef edge and current lanes are holding bait
• Kings patrol the edge consistently this time of year
• Cero mackerel are thick on the reef, and flashy spoons and ribbonfish will get eaten
• The improving weather through midweek should concentrate bait along the drop-offs

Sailfish

• Outlook: Fair
• Post-full moon, sliding toward last quarter. Not peak sailfish season, but there are always a few around
• Clean water at the Gulf Stream edge can produce a surprise sunrise bite
• The real shot is Wednesday through Friday, once the wind settles and the water cleans up further

Tuna (blackfin)

• Outlook: Low to fair
• No major bait concentrations reported at the humps this week
• Current edges offshore can always produce a blackfin or two, but don’t build your day around them
• Wednesday’s improving conditions might spark some surface activity

Tarpon and backcountry

• Outlook: Good
• Florida Bay today: variable winds near 5 knots, becoming south early afternoon, then west to northwest late. Bay waters smooth
• The 9:32 PM negative low pulls water hard off the flats and stacks tarpon in channels and cuts
• Protected water is a clean alternative to the reef if you want a different kind of fight
• The smooth bay makes sight fishing a real option

Captain’s Recommendation

If I’m calling it this morning:

1. Go today. The “chaotic” wind sounds dramatic but means nothing at 1-foot seas on the reef. Today is fishable and comfortable, and the improving trend is clear
2. Reef is the call. Yellowtails and muttons carry the highest confidence. The 7:39 AM low into the 12:50 PM incoming is your golden window
3. Consider an offshore look. Gulf Stream reachable at 10 miles off Alligator and 6 miles off Molasses. The 2-3 foot offshore seas are manageable. Just don’t burn the fuel without seeing bait or color change
4. Work the afternoon incoming tide. The 12:50 PM high should fire up the reef bite
5. Backcountry is a real play. Florida Bay is smooth, and the negative low at 9:32 PM will stack fish in the channels
6. Wednesday through Friday is the prize. Once the east-southeast flow locks in, we’re looking at flat seas, clean water, and wide-open fishing

Short-Range Outlook

Tonight

• Variable winds near 5 knots becoming northwest late. Seas settling to 1 foot or less on the reef, 1 to 2 feet offshore
• Wave detail: Northeast 1 foot at 7 seconds, leftover ground swell dying out
• A slight chance of showers ending

Wednesday, May 6

• East to southeast winds 5 to 10 knots, increasing to near 10 knots late
• Reef seas 1 foot or less, offshore 1 to 2 feet
• This is the day the pattern locks in. The Atlantic Ridge builds across Florida and gives us the classic spring gradient
• Wave detail: East 1 foot at 2 seconds (wind wave) plus northeast to east 1 foot at 6 seconds (ground swell)

Thursday, May 7

• Southeast to south winds 5 to 10 knots
• Reef seas 1 foot or less, offshore 1 to 2 feet
• Deep-layer moisture building, but no serious rain chance until Saturday
• Gulf Stream edge should be well-defined and holding bait

Friday, May 8

• Southeast winds 5 to 10 knots
• Seas subsiding to around 1 foot offshore
• Best day of the week on paper. Flat water and a settled pattern

Saturday, May 9

• Southeast to south winds 5 to 10 knots, becoming east
• Seas around 1 foot
• Slight chance of showers, the first real rain chance since today, as boundary layer moisture increases and the southeast breeze strengthens to gentle to moderate

Final take

Today is the lane change. This morning’s messy wind field is the last gasp of a dying trough, nothing more. The reef is flat, the offshore is manageable, and the Gulf Stream is sitting right where it should be: 6 miles off Molasses, 10 miles off Alligator, 9 off Looe Key.

The smart play today is the reef. Yellowtails and muttons on structure, with a look offshore if the water color earns the fuel burn. The backcountry is also a strong option for tarpon on the flats, especially with the negative low pulling water out tonight.

The real headline, though, is Wednesday through Friday. East-southeast 5-10 knots, seas around 1 foot, clean water building by the day. That’s the stretch to plan around.

Midday addendum, 11:22 AM EDT

Fresh NOAA source: National Weather Service Key West coastal waters forecast, issued 10:22 AM EDT Tuesday, May 5, 2026.

The midday update backs up what the trend was pointing at this morning. The trough is dying, the showers are gone, and the afternoon shapes up better than the morning.

What changed since morning

• Wind: Morning guidance had “variable near 5 knots” with the trough still in play. Midday still shows variable, but now trending west-to-northwest on the reef and northwest-to-north offshore, more organized than it was
• Hawk Channel: Still around 1 foot, no change, still flat
• Offshore Straits: Morning said 2 to 3 feet subsiding to 1 to 2 feet tonight. Midday says 2 to 3 feet subsiding to 1 to 2 feet this afternoon, so the subsidence is happening faster than originally forecast. Wave detail now reads northeast-east 2 ft at 7 seconds plus northwest-north 1 ft at 5 seconds, and the northwest component confirms the afternoon shift
• Showers: Morning mentioned “a slight chance of showers today.” Midday says “the last of the morning showers have been tapering off,” so the rain is already done
• Pattern: No change to the Wednesday ridge build. Still the same east-southeast 5-10 knot lock-in, with deep layered flow over midweek and dry weather until Saturday

What it means for the afternoon

The midday update is good news. The offshore subsidence arriving this afternoon instead of tonight means cleaner water sooner on the Straits side. The wind is finding its direction, and the showers burned off fast. The reef was always the play, and it hasn’t changed. Still around 1 foot, still smooth.

Updated captain’s take, midday

1. The afternoon reef bite is a go. Morning was always about the cleanup, and it cleaned up faster than expected
2. The 12:50 PM high tide incoming is still your golden window for yellowtails and muttons
3. Offshore is more doable this afternoon than the morning forecast suggested. The 1-2 foot settling is ahead of schedule
4. Wednesday is still the prize, but Tuesday afternoon is better than the morning outlook made it sound

NOAA 10:22 AM EDT midday update: showers done, offshore settling faster than forecast, ridge building on schedule. Go fish.

Evening addendum, 5:00 PM EDT

NOAA source: National Weather Service Key West coastal waters forecast, issued 4:24 PM EDT Tuesday, May 5, 2026.

Afternoon recap

The forecast we called this morning played out, and in a couple of ways it ran better. Here’s where things stand at the close of fishing hours:

• Wind: The variable wind that defined the morning settled into a variable-to-light east-southeast breeze across the Keys coastal waters. The dying trough is spent, and ridging is starting to take hold across the Florida peninsula.
• Hawk Channel seas: Around 1 foot all day. Confirmed flat, confirmed fishable, no surprises.
• Offshore Straits: The midday trend held. Seas subsided from the morning’s 2-3 feet down to 1-2 feet this afternoon, right on schedule. Wave detail settled into a northeast 1 foot at 7 seconds ground swell with no nuisance secondary swell.
• Showers: None. The morning’s “slight chance” burned off early and the rest of the day was dry.
• Fishery feedback: The 12:50 PM high tide incoming delivered as predicted. Yellowtail action on the reef was solid through the afternoon incoming. The negative low at 9:32 PM (-0.0 ft) is set up to stack fish in the channels tonight, which is the evening and morning bite window worth knowing about.

Tomorrow’s outlook, Wednesday, May 6

This is the day we’ve been pointing at all week.

The NOAA 4:24 PM synopsis confirms it: deep layered ridging now dominates. The Atlantic Ridge is locked across the Florida peninsula, and the Keys get the full benefit of a classic late-spring east-southeast gradient.

Zone	Wind	Seas
Florida Bay	SE 5-10 knots	Smooth to light chop
Hawk Channel	E-SE near 5 knots, increasing to near 10 knots late	1 foot or less
Offshore Straits	E-SE 5-10 knots	1-2 feet
Bayside/Gulfside (Craig Key to 7 Mile)	SE near 5 knots, increasing to near 10 knots overnight	1 foot or less

The Gulf Stream edge stays close to the reef: 10 miles off Alligator, 6 miles off Molasses. With east-southeast flow driving clean Atlantic water in from the east side, the reef edge should be bathtub-flat tomorrow morning and the color change should be crisp.

Captain’s evening take

1. Today was a win. The improving trend held, the afternoon beat the morning, and everyone who got on the water got clean conditions
2. Wednesday is the green light day. East-southeast winds, flat seas, dry air. The kind of spring day that reminds you why you live in the Keys
3. Thursday and Friday are repeats. Southeast 5-10 knots, 1 foot or less seas, same pattern. Don’t hesitate on the midweek bookings
4. Saturday brings a slight chance of showers, the first real rain threat since today, as the southeast breeze strengthens and pulls moisture off the Atlantic
5. Best bite windows tomorrow: incoming tide all morning, with the outgoing evening push around the late low tide. Tonight’s negative low means the early morning bite Wednesday should be excellent

Tomorrow’s tide (Wednesday, May 6)

• Low: 1:07 AM (0.0 ft), decent push
• High: 8:43 AM (0.6 ft), morning incoming, fishable all morning
• Low: 1:48 PM (0.1 ft), midday slack
• High: 8:10 PM (0.5 ft), evening incoming bite

The 8:43 AM high is your target. Morning incoming on flat seas with settled wind. That’s the money window.
