The Lowdown
Alright, let’s get into it. We’re looking at Bagasse, a reef break that’s fairly consistent and exposed to the north. The water temp is sitting about average for this time of year at 84°, so nothing wild there.
Honestly, the next week and a half is a bit of a grind. There’s no real standout session until we get to the end of the month. From Tuesday the 25th right through to Sunday the 30th, we’re looking at mostly poor to marginal conditions. The swell is hanging around 5ft to 5ft from the ENE, but the period is short, mostly 7 to 8 seconds, and the wind is a moderate cross-shore or cross-off breeze. Wave energy is moderate (186 to 499) but it’s just not coming together. A few mornings look clean, but the surf is weak and messy.
It’s not until Monday the 31st of August that things start to change. The morning brings a 6ft ENE swell with a longer period of 11 seconds, and the energy jumps to 758 – that’s moderate to strong. The wind is light and cross, so there’s a little bump, but it’s marginal. Then Monday afternoon is where it’s at: 5ft from the ENE, 11-second period, light east wind that’s cross-off, and the energy is still strong at 558. The conditions are clean. That’s the best of the run right there. Bagasse is a reef, so that longer period groundswell will wrap in nicely and give you some proper shape. Crowds are possible, so keep an eye out.
Tuesday the 1st of September still has some clean morning waves – 4ft from the ENE, 9-second period, light cross-off wind – but it’s smaller. Afternoon drops right off to 3ft.
From the 2nd of September onward, it’s mostly poor again. The swell stays around 4ft to 6ft from the E and ENE, but the period drops back to 7 or 8 seconds, and the wind picks up to a fresh breeze (15-18 mph). The energy is moderate (198 to 357) but the quality just isn’t there. There’s a brief moment on the morning of the 8th of September that’s marginal, but it’s not worth getting excited about.
So, bottom line: if you’ve got a window, make it Monday afternoon the 31st of August. That’s the one to aim for.

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.
