The Lowdown
Alright, let’s talk about what’s happening. The first week or so at Bagasse is pretty flat and uninviting. The wind is mostly out of the east, blowing cross-off or cross-shore, which doesn’t do this reef any favors. The swell is small, under 4 ft, with short periods of 7 to 8 seconds, and the combined energy is low. The water is warm at 84°, which is right where it should be for this time of year. It’s a slow start, and I wouldn’t rush to get wet.
We get a little bump around Thursday the 27th of August. The swell picks up to 5 ft from the ENE, with an 8-second period, and the combined energy climbs to 380. The wind stays cross-offshore, keeping it clean, but it’s only a marginal forecast. Not a home run, but a sign of life.
Now, the one that stands out, the one you circle on your calendar, is Sunday the 30th of August. A proper groundswell is coming in. The swell is 5 ft from the east, but the period is 15 seconds – that’s a very long period, giving it real punch. The combined energy is a massive 1156 (very strong). The wind is light from the east at 9 mph, a gentle breeze, so the surface will be clean. This is the best of the bunch. The swell builds to 6 ft by the afternoon. This is a reef break, so that long period will wrap around and give you some proper, lined-up waves. It’s a bit too big for beginners, but intermediate and up will have a blast. The spot is fairly consistent, and crowds are possible, so get there early.
Monday the 31st of August is still good. The swell is 7 ft in the morning from the ENE, with an 11-second period. The combined energy is still strong at 913. The wind stays light and cross-offshore. It’s a solid, clean day, but it’s getting into expert territory with that size. After that, the energy fades, and we’re back into that poor-to-marginal pattern through the first week of September, with the swell dropping to 3 ft by the 4th.
So, the clear winner is that Sunday the 30th of August. The long-period east swell, the light wind, and that reef setup are going to be the best day in this whole 16-day run. The later stuff around the 7th of September has some size (6 ft) but the wind is blowing 19 mph, which will mess up the surface. It’s a long wait, but that one day is a gem.

Information about the Bagasse Surf forecast
The above surf forecast table for Bagasse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bagasse can be found by selecting the local surf guide option on the grey menu. Our Bagasse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bagasse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bagasse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Bagasse is 24 km (15 miles) from Sainte-Marie. If you plan a holiday in Martinique, look for hotels and other accommodation in Sainte-Marie. Sainte-Marie has rooms for a wide range of budgets as well as car hire and transport links.
