Fishing Windward Islands

The Windward Islands fish the Atlantic facing edge, and the chart is built to read it. Martinique, St Lucia, St Vincent, Grenada and Barbados all sit where the shelf drops into deep water and strong current lines run along the island chain. You are hunting the breaks and the color changes near that edge, where cooler or greener water meets warm blue and bait gets pinned.

Read the layers together rather than any single signal. An SST break that marks a temperature edge, a chlorophyll color change that shows where the water turns from green to clean blue, and the depth structure where the shelf falls away. Where those overlap, bait holds and the pelagics work through. Barbados is known for a winter wahoo run, and the same approach of finding edges and current lines helps you time and locate it instead of guessing.

The headline species are blue marlin, wahoo, yellowfin tuna and mahi. Wahoo and tuna favor the sharp drop and the current seams, mahi drift the color changes and any floating structure, and blue marlin range the deep water off the edge. The strong current here does the work of concentrating bait, so pay attention to where it bends around the islands and over the dropoff.

Treat the chart as intelligence, not a guarantee, and remember it is a planning tool and not for navigation. Seasons, runs and regulations change every year, so confirm current local rules and closures before you fish. Satellite SST and chlorophyll show you where the water has looked promising, but conditions shift daily, so use the chart to build a plan and let the ocean confirm or change it.

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.

Windward Islands FAQ

Does ReelTemps use local buoys in the Windward Islands?
No. There are no NOAA NDBC buoys in these waters, so there is no buoy calibration or buoy ground truth like we rely on in US waters. The data is satellite only, meaning satellite sea surface temperature and chlorophyll, so treat it as intelligence and verify on the water.
When is the Barbados wahoo run and how does the chart help?
Barbados is known for a winter wahoo run, though the timing shifts year to year. The chart helps you find the temperature breaks and current lines along the Atlantic facing edge where wahoo concentrate, so you can focus your search instead of covering empty water. Always check current local rules before you go.
How should I read the breaks off Martinique, St Lucia, St Vincent and Grenada?
Combine signals. Find an SST break, a chlorophyll color change and the point where the shelf drops into deep water. Where those overlap, the strong current pins bait and the pelagics work through, especially where the current bends around an island.
What species should I expect?
Blue marlin, wahoo, yellowfin tuna and mahi are the headliners. Wahoo and tuna hold on the sharp drop and current seams, mahi drift color changes and floating structure, and blue marlin range the deep water off the edge.
