Captain's Log — April 3, 2026

Friday and the wind is still running the show. Strong high pressure parked over the central North Atlantic keeps pumping fresh to strong easterlies through the weekend. Small Craft Advisory posted everywhere that matters. The good news? This pattern finally breaks Sunday into Monday — and by Tuesday we’re looking at near-calm conditions before the next front rolls in Tuesday night.

Conditions

Wind: East 20 knots today, building to 20-25 tonight. The pattern peaks tonight into Saturday morning, then slowly backs off. Winds tend to lull in the afternoon and peak overnight into early morning — plan accordingly. By Sunday, dropping to E 15, and by Monday we’re talking E 5-10. That’s your window.

Hawk Channel (Alligator Reef to Tennessee Reef zone): Small Craft Advisory. East 20, seas 3-5 feet with occasional 6-footers. Rough nearshore. This is fishable for experienced boats but not fun. Short-period chop will test your patience and your knees. Saturday is similar. Sunday drops to 2-3 feet — much more manageable.

Straits of Florida: Small Craft Advisory. East 20-25, seas 5-8 feet, occasionally to 9. Wave detail: East 7 feet at 7 seconds. That’s short-period slop stacked on top of itself. Offshore is a rough ride today and tomorrow. The Gulf Stream edge sitting 15 NM southeast of Alligator Reef means you’re punching into it the whole way out. Not worth it unless you’ve got a serious boat and a crew with iron stomachs.

Florida Bay: Small Craft Advisory. East 20, rough. The backcountry has some protection in the lee of the islands, but open bay crossings are going to hammer you. Barnes Sound and Blackwater Sound will be sloppy.

Gulf Stream Position: 15 NM SE of Alligator Reef Light (Islamorada), 7 NM SE of Molasses Reef (Key Largo), 20 NM SE of Sombrero Key (Marathon). The Stream is pushed in tight off the Upper Keys — when conditions lay down, the run out will be short.

Slight chance of showers through the period, nothing organized.

Tides — Vaca Key (Islamorada Area)

• High: 4:41 AM — 0.53 ft
• Low: 7:43 AM — 0.26 ft
• High: 2:41 PM — 0.68 ft
• Low: 8:33 PM — -0.27 ft

Negative low tide this evening — flats will drain out. Morning incoming tide is modest.

Reef-by-Reef Breakdown

Molasses Reef (Key Largo)

Gulf Stream is only 7 NM off — the closest it gets anywhere in the Keys. When conditions calm (Sunday-Monday), this is prime territory for sailfish and mahi on the edge. Today? The 3-5 foot chop in Hawk Channel makes the run uncomfortable. Yellowtailing on the reef is possible if you can hold position in the current and chop.

Conch Reef

Similar story to Molasses — exposed to the full east fetch. Drift fishing for yellowtail is tough when the boat is hobby-horsing in 4-5 foot seas. Best bet is to tuck in on the west side of the reef and work the lee. Mutton snappers are staging for their spring spawn — live crabs or lobster tails on the bottom.

Davis Reef

Sitting between Conch and Alligator, Davis gets the full brunt of the easterly. Exposed and rough today. Skip it until Sunday unless you’re specifically targeting bottom fish in the lee.

Crocker Reef

Slightly more protected due to geography, but still dealing with 3-4 foot seas. If you’re going out in the Upper Keys today, Crocker might offer marginally better conditions than the more exposed reefs. Yellowtail and cero mackerel around the reef edges.

Alligator Reef (Captain’s Backyard)

East 20, 3-5 feet. The lighthouse is taking a beating. Gulf Stream is 15 NM out — tantalizingly close but today’s not the day. Sunday-Monday is your play. Kingfish should be patrolling the reef edge as water temps hold in the upper 70s. Yellowtail are reliable here — chum hard and fish the down-current side.

Tennessee Reef

Westernmost of the Upper Keys reefs and slightly more sheltered from due east wind. If you MUST fish today, Tennessee offers the most reasonable conditions of the group. Bottom fishing for yellowtail and mutton snapper. The reef structure here holds fish even in rough conditions.

Species Outlook

🐟 Sailfish: Forget it today and Saturday. The Stream is right there but 5-8 foot seas make it a rodeo. Sunday-Monday window is prime — Stream at 15 NM, seas dropping to 2-4 feet, east 10-15 diminishing. That’s your shot.

🐟 Mahi-Mahi: Same as sailfish — wait for the window. When the wind dies, run the color changes and weed lines on the Stream edge. April mahi should be showing up.

🐟 Yellowtail Snapper: The most realistic target today. Fish the reef in the lee, heavy chum, small hooks. They bite in rough water if you can hold the boat.

🐟 Mutton Snapper: Pre-spawn staging on the deeper reef edges. Live bait on bottom, 60-90 foot range. Full moon was April 1 — the bite should still be hot through the weekend.

🐟 Kingfish: Patrolling Alligator and Tennessee reef edges. Slow-troll live bait or bump the bottom with kingfish rigs. Best when current is moving.

The Play

Today-Saturday: Stay home or fish protected reef spots for yellowtail and bottom fish. The juice isn’t worth the squeeze offshore.

Sunday-Monday: This is the window. East 10-15 dropping to 5-10, seas 1-3 feet. Run the Stream edge for sails and mahi. The Gulf Stream is only 15 NM off Islamorada — you can be on the edge in 30-45 minutes. Book it if you haven’t already.

Tuesday: Another front arrives Tuesday night. NE 20-25 by Tuesday evening with seas building to 4-7. Get your offshore fix Monday because Tuesday afternoon will shut it down again.
