The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Bagasse over the next couple of weeks.
Straight up, I’m gonna be honest with you – it’s a tough stretch. The forecast is a real mixed bag with a lot of waiting around. For the first five days, from Thursday the 20th of August right through to Monday the 24th, the wave energy is weak (between 163 and 377), the swell is short-period and the wind is mostly cross or cross-off, which is a bit of a buzzkill. The water temp is a balmy 84°F, which is pretty normal for this time of year, so at least you won’t need a steamer.
The first real glimmer of hope pops up on Tuesday the 25th of August. The morning shows a pulse of 7ft swell from the East with a period of 10 seconds, and the combined energy jumps to 910 (moderate energy). The wind goes cross-off, so it’ll be clean. This is a fun, intermediate-sized wave. It’s not a world-beater, but it’s the best we’ve seen so far. The swell direction is East, which is a solid match for this spot. Keep in mind, Bagasse is fairly consistent, but it can get crowded sometimes, so get in early.
Now, if you’ve got some patience, the real standout is brewing for Saturday the 29th of August. The morning session is looking like the pick of the entire forecast. We’re talking a solid 10ft swell from the East with a 10-second period (strong to very strong wave energy at 1957). That’s a proper groundswell, and at this size, it’s strictly for the experienced crew – this is not a beginner wave. The wind is cross-off from the East at 19 mph, keeping things clean. The period is over 8 seconds but under 11, so you’ll get solid, well-shaped waves, not just close-outs. It’s a reef break, so it should handle that size well. The Saturday afternoon drops to 7ft, still solid, but the morning is the moment.
After that, the swell backs off again. Sunday the 30th and Monday the 31st see energy dropping back to moderate levels (402 to 183), and the wind is more cross than cross-off, so it gets a bit lumpy. The first week of September is a bit of a write-off – weak swell, short period, and mostly poor conditions. There’s a marginal window on the morning of Friday the 4th of September with a 5ft, 7-second swell, but it’s nothing to write home about.
So, the bottom line: if you’re looking for a wave, your best bet is the morning of Tuesday the 25th of August for a clean, fun session, but the one to really circle on the calendar is the morning of Saturday the 29th of August. That’s the big one for expert surfers only. The gaps between these sessions are long, so be ready to wait.

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.
