The Lowdown
Alright folks, Rusty here. Let's have a look at what Bagasse has in store for us over the next couple of weeks. I gotta be straight with you – it’s a tough stretch. We’ve got a solid-looking reef break that loves a northerly swell, but the ocean isn't cooperating much.
The water temperature is sitting around 85°, which is about 0.9° warmer than usual for this time of year. Nothing crazy, just a touch of tropical bathwater.
We start off on Saturday the 12th, and it’s pretty grim. There’s some chest-high 5ft swell from the ENE, but it’s short-period windswell (7 seconds) with a strong 16 mph cross-shore breeze. The combined energy is moderate (232), but the surface is chopped up. It’s a write-off. Sunday the 13th through to Thursday the 18th is more of the same story – waist to chest-high, short-period swell, and always a moderate breeze keeping things messy. You’ll see some cleaner conditions on the morning sessions, but the wave quality is poor to marginal at best. It’s a long, frustrating gap with nothing worth paddling out for.
Now, there is a glimmer. On Saturday the 19th of September, the morning session looks like the one bright spot. The wind swings light and offshore from the ESE at only 6 mph, which should keep the lineup clean. The swell drops to 3ft from the E, still a short 7-second period, but the combined energy jumps to 200. The forecast says "expect good surf conditions" – the first time we’ve heard that. It’ll be small and clean, a proper longboard or funboard morning. Keep in mind, Bagasse can get a crowd sometimes, so get there early.
After that little window, it’s back to the doldrums. From the 20th right through to the 27th of September, we are looking at tiny swell (2ft to 3ft) with weak energy, often under 100. The wind stays messy or cross-off, but there’s just no power in the water. Sunday the 27th afternoon sees the energy drop to a weak 101, and it’s all over.
If you’re a hardcore kiter, these windy, choppy days in the middle of the period might look fun, but for a surfer? It’s a paddling session at best.
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.
