Weather Overview

The pattern shift we’ve been tracking all week has arrived. The frontal boundary that kicked up west-northwest winds through Wednesday and Thursday has pushed through, and the pressure gradient has collapsed. This morning brings northwest winds 5-10 knots trending to southwest near 5 knots by afternoon. Seas across all zones are 1 foot or less — as flat as it gets in the Florida Keys.

This is textbook post-frontal conditions: light variable wind, a settling sea state, and building high pressure sliding across the western North Atlantic. The only weather concern is a slight chance of showers and thunderstorms — isolated afternoon pop-ups over land, nothing organized.

Bottom line: If you’ve been waiting for a flat day to punch offshore, this is it. Friday is the window between wind events.

Wind & Sea State

Zone	Wind	Seas
Hawk Channel (Upper Keys)	NW 5-10 kts → variable, becoming SW 5-10 kts afternoon	1-2 ft → subsiding to 1 ft or less
Hawk Channel (Mid Keys)	NW 5-10 kts → variable	1-2 ft → 1 ft or less
Florida Bay	NW 5-10 kts → SW near 5 kts	Smooth to light chop → smooth
Bayside/Gulfside	NW to N 5-10 kts → SW to W 5 kts	1-2 ft → 1 ft or less
Straits of Florida (Offshore)	Variable 5-10 kts	1-2 ft → 1 ft or less

The Collapse: NOAA’s synopsis nails it — “a waning pressure pattern will support generally slackening breezes through this afternoon.” The gradient between the departing low over central Florida and the building Atlantic high has gone slack. Winds go variable, seas flatten, and the residual long-period NNE swell from earlier this week has finally died.

Reef-by-Reef Breakdown

Molasses Reef (Key Largo)

NW wind 5-10 knots early, going variable through the day. Seas around 1 foot or less on the reef. The Gulf Stream edge sits tight at 4 NM southeast — per NOAA’s May 12 positioning. This is about as close as the Stream gets. Morning incoming tide (low at 9:46 AM) will push clean bluewater over the reef as the flood builds through late morning into the afternoon. The afternoon high tide at 3:20 PM creates a solid afternoon bite window.

Target: Yellowtail on the chum slick, mutton drifting the edge, kingfish on the reef face.

Conch Reef

Light variable wind all day. Clean water from the closely positioned Stream edge. The morning low (9:46 AM) transitions to incoming — expect bait to flood onto the reef structure around 11 AM through 2 PM. The flat conditions make this ideal for anchoring up on the ledge in 60-80 feet.

Target: Muttons, mangroves, yellowtail. Cero mackerel on flashy spoons along the ledge.

Davis Reef

Variable wind near 5 knots, seas 1 foot or less. The wreck structure in 60-80 feet is the play. With the Stream pinned close (roughly 5-6 NM southeast), clean water is pushing onto the reef. The morning-to-afternoon flood tide is the prime window.

Target: Mangrove snapper, yellowtail, grouper on structure. Kingfish trolling between Davis and Crocker.

Crocker Reef

Northwest wind 5-10 knots going light variable. Seas settling to 1 foot or less. One of the most comfortable anchor spots today. The structure in 50-70 feet holds muttons, grouper, and yellowtail. The 9:46 AM low to 3:20 PM high flood tide is the longest and most productive feeding window of the day.

Target: Mutton snapper on the incoming drift, grouper on the deep structure.

Alligator Reef

The flagship Islamorada reef is sublime today. Light variable wind, flat seas, and the Gulf Stream edge at 6 NM southeast. The afternoon incoming tide (peaking at 3:20 PM) will push bait tight to the reef. This is a dream day for Alligator — easy to anchor, easy to chum, easy to make the quick bluewater run if the action goes offshore.

Target: Muttons, yellowtail, kingfish. The color change at 6 NM is a 10-minute run.

Tennessee Reef

Exposed to residual northwest breeze early, but it fades through the morning. Seas flat. The deeper ledge at 30-40 feet holds grouper and snapper. Less traffic midweek. If you want solitude and structure, Tennessee on a flat day like this is money.

Target: Grouper, snapper. Bait should be stacked on structure.

Offshore Outlook (Straits)

Variable winds 5-10 knots. Seas 1-2 feet subsiding to 1 foot or less. Wave detail from NOAA: residual NW 2 feet at 5 seconds fading to nothing. This is flat water — no significant groundswell, no wind chop piling in.

Gulf Stream position (NOAA May 12):

• 6 NM SE of Alligator Reef Light (Islamorada)
• 4 NM SE of Molasses Reef Light (Key Largo)
• 3 NM SE of Carysfort Reef Light (Ocean Reef)
• 7 NM SE of Sombrero Key Light (Marathon)
• 6 NM S of Sand Key Light (Key West)

The Stream is pinned tight to the upper Keys reef line. The bluewater edge is a short run from any upper or mid-Keys launch point.

Species Outlook

• Mahi-Mahi: Strong. The Gulf Stream is 4-6 NM off the reef. Clean bluewater, scattered weed lines from the earlier wind event. Bull mahi still in the pattern. Run to the color change and troll. Seas are flat — the ride is painless.
• Blackfin Tuna: Good. Morning bite on the humps and reef edges. The flat sea state makes the humps accessible. Islamorada Hump and Key Largo Hump are the plays.
• King Mackerel: Good. Smokers working the reef edge. With the Stream pinned tight, kings are stacked along the color change. Trolling the edge between Alligator and Molasses will produce.
• Sailfish: Fair to Good. Late-season sails lingering near the Stream edge. The flat conditions make the kite bite viable. The 9:46 AM low through 3:20 PM high incoming tide should push bait to the edge.
• Yellowtail Snapper: Very Good. Classic conditions for a chum slick. Light wind, flat seas, incoming tide. Anchor up on the reef in 40-60 feet, chum heavy, and load the cooler.

---

Florida Bay & Backcountry

NW winds 5-10 knots becoming southwest near 5 knots in the afternoon. Bay waters smooth to light chop, becoming smooth. A slight chance of showers and thunderstorms.

After the wind surge of the last few days, the flats will be settling today. The morning incoming tide (post 9:46 AM low) pushes clean water back onto the grass flats.

Target species: Redfish on the flats, trout, snook in the passes and creeks. Tarpon moving through channels on the flood tide. Bonefish on the sand flats — the light wind makes sight fishing viable.

Weekend Outlook

Saturday, May 16 — NEW MOON

• East winds near 10 knots, increasing to 10-15 knots
• Seas around 1 foot, building to 1-2 feet
• A slight chance of showers and thunderstorms
• New moon + building east breeze + increasing tides = strong fishing
• The tidal swing increases significantly — expect bigger water movement, more bait push, and active feeding

Sunday, May 17

• East winds near 15 knots
• Seas 2-3 feet (Hawk Channel), 3-4 feet offshore (occasionally 5)
• A chance of showers with a slight chance of thunderstorms
• The east trade wind regime re-establishes. Fishable but significantly bumpier than Friday/Saturday.

Monday, May 18

• East winds 15-20 knots early, easing to near 15
• Seas 3-5 feet offshore, occasionally 6 feet
• Choppy nearshore
• A chance of showers

Tuesday, May 19

• East winds near 15 knots
• Seas 2-3 feet nearshore, 3-5 feet offshore
• Moderate to choppy

Pattern: Friday is clean, Saturday is fishable, Sunday through Tuesday gets progressively windier as the Atlantic high re-establishes the east trade wind regime. Fish today or tomorrow morning.

Tides Detail

Time	Height	Direction	Best For
9:46 AM	0.2 ft (Low)	Outgoing slack → Flood begins	Early reef setup
10 AM - 2 PM	Rising 0.3 → 1.2 ft	Incoming building	Peak reef bite
3:20 PM	1.7 ft (High)	Peak flood	Maximum water push
3:20 PM - 8 PM	Falling 1.7 → 0.7 ft	Outgoing early	Afternoon edge fishing
8 PM - 11:41 PM	Falling 0.7 → 0.1 ft	Outgoing late	Night bite tapering

The single high tide at 3:20 PM creates a long incoming window from late morning through mid-afternoon. That’s your money window. The new moon tomorrow will amplify Saturday’s tides — significantly more water movement.

The Bottom Line

Rating: 🟢 Good to Very Good — the best conditions day of the pattern

This is the day we’ve been waiting for since Wednesday. The wind surge is done, the seas are flat, and we’re one day out from the new moon.

Your game plan:

1. Launch early — light NW breeze at dawn, flat seas. No excuses.
2. The Gulf Stream is 4-6 NM off the reef — the shortest bluewater run of the spring.
3. Fish the 10 AM to 3:30 PM incoming tide — the flood pushes bait and clean water over the reef structure.
4. Mix reef and offshore — yellowtail/mutton on the reef in the morning, bluewater run midday for mahi and blackfin.
5. New moon tomorrow means Saturday is the absolute best weekend day for tide movement. Saturday’s east breeze picks up but stays fishable.

Captain’s call: If you can only fish one day this week, split between today and tomorrow. Today wins for flat water comfort. Tomorrow wins for tide-driven action. Either way, the water is clean, the Stream is close, and the fish are biting.

Midday Addendum — 10:23 AM Update

NOAA’s 10:23 AM refreshed forecast confirms the morning outlook with no surprises. Here’s what refined:

Wind: The morning’s NW 5-10 knots is now observed as NW near 10 knots across all zones, with the afternoon switch to variable/southwest confirmed on schedule. Hawk Channel has already gone variable near 5 knots in many spots. Florida Bay saw NW 10 knots this morning but is transitioning to S/SW as expected.

Seas: Forecasts tightened to 1-2 feet subsiding to 1 foot or less across all zones. The 4:18 AM guidance was slightly more conservative (1-2 feet settling). The midday confirms seas are actually laying down faster than originally projected.

Weekend Update — No Change: Saturday east winds 10-15 knots, Sunday east 15 knots building to 15-20 knots Sunday night. Monday/Tuesday east 15-20 knots with seas 2-4 feet, occasionally 5 feet in Hawk Channel. The trade wind re-establishment is holding firm.

Bottom line: The morning call stands. If anything, conditions are slightly better than forecast — flatter, faster wind drop, cleaner afternoon. The midday high tide at 3:20 PM is lining up with glassy conditions. If you aren’t on the water right now, you’re missing one of the best afternoons of the month.

Addendum based on NOAA FZUS52 KKEY refreshed 10:23 AM EDT. No changes to synopsis — conditions tracking exactly as modeled.

Evening Addendum — 4:26 PM Update

NOAA’s 4:26 PM EDT evening issuance locks in the day’s outcome and refines the weekend outlook. Here’s the evening read:

Afternoon Recap — How Today Played

The pattern delivered exactly as forecast. Early NW 5-10 knots went variable by midday, then settled to east-southeast 5-10 knots by late afternoon — textbook post-frontal transition. Seas stayed 1 foot or less across all zones. The 3:20 PM high tide pushed clean Gulf Stream water over the reef structure during peak afternoon warmth.

The morning’s lingering NW swell (1 foot at 5 seconds) has faded to a minor background signal. As of 4:26 PM, the Straits show east 1 foot at 2 seconds and northwest 1 foot at 5 seconds — essentially flat with a faint residual. The variable wind zone has fully flipped to the east-southeast regime.

What actually went down: Light variable morning, glassy by 10 AM, east-southeast breeze filled in late afternoon. Perfect reef fishing window 10 AM to 3:30 PM as predicted.

Tonight’s Outlook

• Variable winds near 5 knots, becoming east to southeast 5-10 knots after midnight
• Seas building slightly: 1 foot or less → around 1 foot
• Hawk Channel: smooth to light chop overnight
• A slight chance of showers drifting through
• Moon: New moon is tonight/tomorrow — dark sky, maximum tidal amplitude

Saturday, May 16 — NEW MOON

• East winds near 10 knots, increasing to 10-15 knots by afternoon
• Seas: 1-2 feet Hawk Channel, building to around 2 feet by evening
• Offshore: 2-3 feet in the Straits (east 2 ft at 3 seconds)
• Bay: Light chop becoming moderate chop
• A slight chance of showers and thunderstorms
• Tidal impact: New moon amplification = strongest tidal swings of the month
• Verdict: 🟢 Fishable. The east breeze builds through the day, but morning will still be comfortable. Peak incoming tide window shifts with the amplified swing.

Sunday, May 17 — The Wind Comes On

• East winds near 15 knots all day
• Hawk Channel: 2-3 feet, moderate chop
• Offshore (Straits): 3-4 feet, occasionally 5 feet
• A chance of showers with a slight chance of thunderstorms
• Verdict: 🟡 Marginal. Fishable for bigger boats. Smaller center consoles will take spray over the bow.

Sunday Night Through Labor

• Sunday night: Winds bump to 15-20 knots, seas 2-4 ft Hawk Channel (occasionally 5 ft), 4-5 ft offshore (occasionally 6 ft)
• Monday: East near 15 knots, seas 2-3 ft Hawk Channel, 3-5 ft offshore (occasionally 6 ft)
• Monday night: Back to 15-20 knots, 2-4 ft Hawk Channel (occasionally 5 ft), 4-6 ft offshore (occasionally 7 ft) — windiest period of the entire forecast
• Tuesday: Eases slightly — east near 15 knots, 2-3 ft Hawk Channel, 3-5 ft offshore (occasionally 6 ft)
• Wednesday: Better — east 10-15 knots, 1-3 ft Hawk Channel, 2-4 ft offshore
• Wednesday night/Thursday: Trending lighter — east 10-15 knots, seas settling further

The Week Ahead Pattern

The NOAA 4:26 PM synopsis says it best: “Light to gentle breezes will prevail tonight and Saturday. High pressure developing over the Southeast will take root across the western North Atlantic over the weekend. As a result, moderate to fresh easterly breezes will peak and lull across the Florida Keys Sunday through Tuesday.”

Translation: The Atlantic high builds in and oscillates. Sunday night and Monday night get the stiffest east winds (15-20 knots). Tues-Wed settles as the high’s center drifts. No major fronts inbound. The trade wind regime is back for the rest of next week.

Fishing Implications

Tonight: Flat calm conditions for night fishing. New moon dark sky. Pop the lights on the reef structure and let the chum do the work. Mangroves, yellowtail, and cero mackerel on the glow.

Saturday AM: Best window of the weekend. East wind builds through the day, so get out early. The new moon drives max tide movement — expect aggressive feeding. The Stream is still pinned 4-6 NM off the upper Keys. Run to the color change in under 15 minutes.

Sunday-Tuesday: East wind chop builds. Offshore gets lumpy (3-6 ft). Focus on the reef ledge in the lee of the wind. Hawk Channel will be manageable for 24’+ boats. The rising tide windows will still produce — just work harder for your bite.

Midweek rebound: Wednesday through Thursday looks lighter — east 10-15 knots, seas settling. Good fishing window for those who dodge the weekend crowd.

Tides for Saturday (New Moon)

Time	Height	Direction
5:02 AM	0.7 ft (Low)	Outgoing slack
10:25 AM	1.8 ft (High)	Peak incoming
4:42 PM	0.2 ft (Low)	Outgoing slack
10:56 PM	1.9 ft (High)	Night high

Notice the dual high/low cycle — the new moon amplifies both highs and lows. The morning incoming (5 AM → 10:25 AM) and the afternoon outgoing (10:25 AM → 4:42 PM) both push significant water movement. Fish the first 3 hours of the morning incoming and the last 2 hours of the afternoon outgoing.

Final Call

• Today (Friday): 🟢 Best conditions of the week. Flat water, clean, fish on.
• Tomorrow AM: 🟢 Still good. Get out early before the breeze cranks.
• Tomorrow PM: 🟡 Fishable. Building east chop but manageable.
• Sunday-Tuesday: 🟡→🔴 Bigger boats OK, smaller boats take a beating.
• Wed-Thu: 🟢 Trending back to good.

Captain’s evening note: The new moon tomorrow is the X-factor. Even with the building east breeze, the amplified tide movement is going to turn the fish on. If today was about flat-water comfort, tomorrow is about feeding activity. They’re different kinds of excellent — pick your poison.
