Fishing Leeward Islands

The Leeward Islands fish as steep drop, blue water country, and the chart is built to read that edge. Off St Martin, St Kitts, Antigua and Guadeloupe the bottom falls away into deep Atlantic and Caribbean water very close to shore, so you do not run far to reach the grounds that matter. The work is finding where warm water, current seams and color changes stack up near that dropoff and in the channels between the islands.

Treat the chart as intelligence, not a guarantee. Layer the pieces together. A clean SST break where warmer blue meets slightly cooler or greener water, a chlorophyll color change that marks a bait line, and the depth structure of the wall or the passes between islands. Where those line up, bait concentrates and wahoo, tuna and billfish tend to follow. FAD fishing is common here, and the same reading of breaks and edges helps you decide which FADs and seams are worth the fuel.

The headline species are wahoo, blue and white marlin, yellowfin and blackfin tuna, and mahi, often called dorado. Wahoo hold tight to the dropoff and the current edges, tuna and mahi roam the color changes and FADs, and marlin work the deeper blue water offshore. Hunt the seams between islands where current accelerates and pushes bait against structure.

Seasons, runs and regulations change every year, so check current local rules and closures before you go. This is a planning tool and it is not for navigation. Satellite SST and chlorophyll point you toward water that has looked right lately, but the ocean moves daily, so treat the chart as a starting hypothesis and let what you see on the water make the final call.

What you get with ReelTemps

From the water

I've tried every temp map out there and they all feel like they were built ten years ago. I'm not exactly a tech guy, but this one actually makes sense the second you open it. First time using it, I marked a break in about 30 seconds the night before and boated bluefin right on it the next morning.

Used to burn half a tank driving around looking for color change or a solid temp break. Now I check ReelTemps before I leave the dock and I know exactly where I'm going. Less time driving around guessing, more time with lines in the water.

Albacore season used to mean a couple hours of homework the night before and just hoping it held up. Now I do most of my research that morning and pull it up on my phone if things change once we're out there. Makes calling an audible a lot easier.

Leeward Islands FAQ

Is the ReelTemps data from buoys or satellites in the Leeward Islands?
It is satellite only. These are foreign waters with no NOAA NDBC buoys, so there is no local buoy calibration or buoy ground truth like we have in US waters. The chart shows satellite sea surface temperature and chlorophyll, which is why you should treat it as planning intelligence and confirm what you find on the water.
How do I use SST and chlorophyll together to find fish here?
Look for places where a temperature break lines up with a chlorophyll color change and real depth structure such as the dropoff, a pass between islands or a FAD. Where a clean warm blue edge meets greener or cooler water over the wall, bait tends to stack and wahoo, tuna and billfish follow.
What are the main target species in the Leeward Islands?
Wahoo, blue and white marlin, yellowfin and blackfin tuna, and mahi, often called dorado. Wahoo favor the dropoff and current edges, tuna and mahi roam the color changes and FADs, and marlin work the deeper offshore blue.
Can I use the chart for navigation between the islands?
No. It is a planning tool, not a navigation chart. Use it to decide where the water looks worth fishing before you leave, then rely on proper charts and your own electronics on the water. Seasons, runs and regulations change every year, so check current local rules too.
