The Lowdown
Alright folks, Rusty here with the 16-day look, and I'm not gonna sugarcoat it – it's a lean stretch. The first real chance of a wave doesn't pop up until Thursday the 10th, so the beginning is a proper write-off.
The only break worth your time during this whole window is Bagasse (reef) . It’s a consistent reef break that faces north, suited for intermediate surfers. The water temp is about what you'd expect for this time of year, nothing out of the ordinary.
Your best bet is Thursday the 10th of September. The morning session has an east swell at 6 ft with an 8-second period, and the wave energy is moderate at 477. The wind is blowing 16 mph from the east, a cross-off that will keep things clean. The afternoon is similar, with a 5 ft swell from the east-northeast and slightly less energy. It's not the set of the summer, but it's the best we've got.
After that? It's a desert. From Friday the 11th all the way to the 25th of September, the forecast is full of "poor surf conditions." The swell sticks between 3 ft and 5 ft, with those short, weak 7-second periods. The wind is a constant cross-off from the east, mostly at 16 mph or more. The wave energy figures stay between 77 and 252, which is weak to low-moderate. Honestly, with that steady cross-off wind and the weak, short-period swell, this setup looks more like a kite surfer's playground than a place for a paddle.
You’ll see a couple of "marginal" tags around the 16th and 18th, with swells around 4 ft to 5 ft, but the period is still short and the wind is still up. By the 21st of September, the swell crashes to just 2 ft with a paltry 42 units of energy. That's a hard pass.
So, here's the bottom line: pencil in Thursday morning, the 10th of September, at Bagasse. That’s your one and only window of opportunity. After that, it’s a long, flat, and wind-blown slog. It’s the kind of run that’s more normal for the area when the weather patterns lock in, but it doesn't mean we have to like it. Keep checking back, but don't sell your board just yet.
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.
