The Lowdown
Alright, Rusty here, let’s break it down. We’ve got a couple of weeks ahead, and honestly, the first bunch of days ain’t much to write home about. You’ll have to be patient.
From Monday the 17th through Sunday the 23rd of August, Bagasse is pretty much a bust. Swell runs from about 3 ft down to 4 ft, but the wind is either cross or cross-off, and the wave comment is “poor surf conditions” the whole time. The combined energy is weak to moderate (414 down to 136). Water temp is about average for the season, so no surprises there. Just a long stretch of nothing worth paddling out for.
Now, Tuesday the 25th of August is your window. That morning, swell bumps up to 6 ft from the ENE with an 11-second period. The wind goes offshore from the SSE at 25 km/h, cleaning everything up nicely. The combined energy climbs to a strong 745. The wave comment says “expect very good surf conditions.” That afternoon, it drops to 5 ft but still stays clean with offshore wind. This is the standout. The swell direction (ENE) matches up well with the reef’s optimum (N), so expect some nice lines. It’s a fairly consistent reef break, but crowds are sometimes a thing, so get out there early. This one’s for intermediates – the size is decent but not crazy.
The next day, Wednesday the 26th, the wind shifts cross-off and the swell drops back to a weak 4 ft to 5 ft with a short 8-second period. The energy falls off to 265. Quality drops fast, back into marginal or poor territory. That kind of small, cross-off stuff hangs around through the end of the month. Not much to get excited about, but forecasts can change.
Then on Tuesday the 1st of September, we get a little glimmer. A 4 ft swell from the ENE, period 9 seconds, with light cross-off wind from the SE at 10 km/h. The combined energy is a weak 244, but the wave comment says “expect good surf conditions.” It’s clean and small – could be fun on a log or a fish, but it’s not a standout.
So, the only day that really delivers is Tuesday the 25th of August at Bagasse. The rest of the two weeks is mostly flat or messy. For the next week, you’re better off finding something else to do.
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.
