The Lowdown
Right, let’s have a look at Bagasse. It’s a reef setup that’s fairly consistent, but the next couple of weeks are looking pretty grim, if I’m being honest. There’s a bit of a nothing start here, really.
We kick things off on Wednesday the 9th of September with some chest-high swell, around 6 ft from the ENE, but it’s short-period stuff at 8 seconds. Combined energy is moderate, coming in at 513, but the real killer is the wind – a solid 16 mph from the east, cross-off. That’s not terrible for shape, but it’s not glassy, and the water’s warm at 85°, which is about average for this time of year. The forecast scores are flat though – it’s just not coming together with any quality, and there’s talk of thunderstorms. Honestly, it’s a bit of a write-off.
Thursday and Friday see the swell dropping slightly, still around 5 ft to 6 ft, but the winds stay up and the period remains short at 8 seconds. The combined energy drops into the high 300s, but the wave comments are all “poor surf conditions.” It’s not looking surfable for enjoyment.
The weekend into the following week is worse. Saturday the 12th has a stormy cross-chop, and Sunday the 13th drops to 4 ft with energy fading to 220. By Monday the 14th, we’re back to 5 ft but with a short 7-second period and a fresh breeze. It’s all just messy and unappealing. There’s a solid gap of days here – from the 9th right through to the 16th – where I wouldn’t recommend paddling out.
We get a little bump on Thursday the 17th of September. Swell picks back up to 5 ft, then 5 ft in the afternoon, period stretching to 8 seconds from the east. Combined energy climbs back to 361, which is at least moderate. The wind is still cross-off at 16 mph, but the wave comment is now “marginal” rather than poor. It’s the best of a bad bunch, but still only a 1 out of 10 in the book. If you’re desperate for a paddle, Thursday morning might be the least ugly option, but don’t expect any standouts.
From Friday the 18th onwards, it’s a slow fade. Swell drops to 4 ft, energy slides into the low 200s, then the 100s, and by the 24th of September we’re down to 3 ft and 67 energy – that’s weak, barely breaking. The wind stays moderate, but there’s just no power or quality.
If I had to pick one moment across the whole 16 days, it’s that Thursday the 17th. The swell direction from the east is close to optimum for this reef, and the cross-off wind is offshore enough to keep things clean. But even then, it’s not firing. The rest is a long, flat, windy blank. With this being a fairly consistent spot normally, it’s a frustrating stretch. Forecasts can change though, so keep an eye out.

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.
