The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming our way for the next couple of weeks. Straight up, it’s a bit of a tough stretch ahead, so don’t expect any world-class days, but there are a couple of windows worth keeping an eye on.
The overall pattern is pretty ordinary. We’ve got a consistent run of moderate cross-offshore winds blowing from the east, with swell heights staying mostly around the 3 ft to 3 ft mark. The combined wave energy is weak to moderate for most of it, sitting between 59 and 128 (moderate energy values) for the bulk of the period. The water temp is a warm 84°F, about average for this time of the year, so no need for a thick suit.
The Best of the Bunch
The only break showing up is Bagasse, a reef setup that’s fairly consistent and exposed to the north for optimum swell direction. The main issue here is that the wind and swell are coming from the east, which isn’t its best angle. Crowds are possible at times here, so keep that in mind.
The closest to a standout comes around Wednesday the 9th and Thursday the 10th of September. Early morning sessions will see the best of it. Swell bumps up to 6 ft to 6 ft from the east-northeast, with a short period of 8 seconds. The combined energy jumps into the strong range – hitting 570 (strong wave energy) on Wednesday morning. That’s the most energy we’ll see. Winds are a fresh 19 mph from the east, which is cross-offshore, keeping the faces reasonably clean. However, with the swell pushing near 7 ft, it's starting to get a bit chunky for the beginners. It’s rideable, but it won’t be a classic, and the short period means it’ll be a bit lumpy and close together.
After that, it fades. From Friday the 12th onward, it’s a slow decline. Swell drops back below 5 ft, and the energy slides back into the weak to moderate range. By the second week, through the 15th to the 20th of September, it’s pretty flat and uninspiring – energy levels dip as low as 59 (weak wave energy). Winds stay up, and the conditions are described as “poor” across the board. There’s a gap of several days with no real recommendations after the 12th, so don’t hold your breath for the second weekend.
The Call: If you’re keen, your best chance is the morning of Wednesday the 9th or Thursday the 10th. It’s not going to be perfect, but it’s the most size we’ll see. For the rest of it, it’s a waiting game. The consistency here is usually a bit better than this, so forecasts can change, but as it stands, it’s a lean run.
Rusty.

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.
