The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for this stretch. Gotta be straight with you – the next couple of weeks are looking pretty grim. We’ve got Bagasse, a reef break that wants north swell, but we’re not getting that at all. What we are getting is a long, drawn-out run of small, weak, and poorly-directed ENE swell with short periods. The water temp is sitting at 85°, which is about average for the time of year, so no surprises there.
The first noteworthy window isn't until Thursday the 10th of September. Thursday afternoon sees a clean 5 ft swell from the ENE, with a period of just 8 seconds. The wind is a cross-off from the east at 15 mph, which will keep the surface clean, but the wave energy is only moderate (376). It’s the best it’s going to get for a while, but it’s still just marginal.
From Friday the 11th right through to Thursday the 25th of September, it’s a wall of mediocrity. We’re looking at a solid 15-day stretch where the conditions are consistently poor. The swell stays small, mostly between 2 ft and 5 ft, with periods hanging around 6 to 8 seconds – that’s short-period, weak stuff. The wind is a constant cross to cross-off from the east, between 9 and 19 mph, so it’s never truly clean and glassy. The wave energy drops off a cliff, from moderate (301) down to weak (54) by Tuesday the 22nd. Honestly, there’s nothing here to get excited about. This setup looks more interesting for kite surfing than paddle surfing.
There is a tiny glimmer on Friday the 25th of September morning. We get a drop in wind to a gentle breeze of 9 mph from the east, with a cross-off direction, and the swell is 4 ft from the east with a period of 7 seconds. The wave comment says “surfable waves but very ordinary conditions,” which is about as generous as I can be. The energy is still weak (162).
So, the outlook is clear: there are no standout days. If you’re desperate, Thursday the 10th afternoon is the cleanest, most energetic it’ll be. After that, it’s a long wait. Forecasts can change, but right now, this is a blank run.

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.
