The Lowdown
Alright, Rusty here again, switching it up for the imperial crew.
First up, the water is sitting at 84.6°F, which is about average for this time of year, so no surprises there.
To be straight with you, the next week and a half is looking pretty flat and ordinary. We’ve got a long gap where there’s just nothing worth paddling out for. From now right through until Friday the 27th of September, the surf is either tiny or just plain messy with cross-off and cross winds. The energy is low, barely cracking triple digits, and the swell is weak and short-period. There’s nothing to get excited about.
Then, things finally start to look a bit more promising towards the very end of the run. On Sunday the 27th of September, we start to see a pulse of energy coming in at Bagasse. It’s not huge, but the combined energy jumps up to 284, which is moderate, and the swell is coming from the east at 4.3ft with a 7-second period. The wind is cross-off from the east at 12 mph, so the surface will be clean. The conditions are still marginal, but after such a long dry spell, it’s something to keep an eye on.
The best of the lot looks like Monday the 28th of September. The swell direction shifts around to the north-northeast with a period of 10 seconds, which is a bit longer and has more push. Swell size drops to 2.6ft, but the combined energy stays solid in the mid-250s. The wind stays cross-off and light, so the waves should be clean and have a bit more shape to them. Bagasse is a reef break, fairly consistent, and this north-northeast swell direction is offshore for it. It’s an intermediate wave, so if you’ve got a bit of experience, this is your window. The crowds can be there sometimes, so you might have some company.
Honestly, this is a lean outlook. A long stretch of nothing, then a couple of days that might just save the run. The earlier calls are pretty solid, but that late September pulse is a longer-range call so keep your fingers crossed. After that, the energy looks like it fades again.

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.
