The Lowdown

G'day, Rusty here. Let's have a look at what's on the table for this stretch. It's a bit of a flat start, so the first surf worth mentioning doesn't kick off until Monday afternoon, the 7th of September, and even then, it's only just hanging on. We've got a solid 3 days of nothing doing before that.

Alright, so the only break in the mix is Bagasse, a reef setup that's fairly consistent. The water's sitting at a normal 84°F for the time of year. The pattern is stubborn: we're looking at a persistent E/ENE swell with a short 7-8 second period. That's windswell, not groundswell, so the wave shape will be a bit crumbly and lacking that real punch.

The first couple of days of the second week, from Monday the 7th through to about Wednesday the 9th, see the swell building. We go from 4ft up to 6ft by Wednesday afternoon. The combined wave energy climbs from a moderate 236 into the strong zone, hitting 629 on Wednesday afternoon. That's decent energy. But here's the kicker – the wind is a cross-offshore breeze from the E all the way through, at 12 to 19 mph. It's a persistent Moderate to Fresh breeze. That cross-off wind is actually a major positive because it will groom the faces, keeping them clean. The swell direction is ENE, and the optimum for Bagasse is N, so it's not a perfect match, but it's getting some exposure.

For the standout session, I'd be looking at Wednesday the 9th afternoon. You've got 6ft of ENE swell with that strong energy (629), and the cross-off wind will have it looking tidy. That's the best on offer for the whole run. It's a reef, so it'll handle that longer-period stuff better anyway, though the period is only 8 seconds, so it's not a classic groundswell. Crowds are a possibility at Bagasse – it's marked as "sometimes" busy, so you might have a few mates out.

After that, the swell slowly backs off through the rest of the week and into the following weekend. By the 13th and 14th, we're back down to 3ft, with energy dropping to weak-to-moderate levels (126-180). The wind stays cross-off, so the surf will still be clean, but small. The second week of the outlook, from the 15th onwards, shows a bit of a pulse again, with 5ft to 5ft ENE swell and moderate energy in the 200s, but the period drops to 6-7 seconds, making it even more jumbled. The wind remains cross-off, so it's rideable, but nothing to write home about.

If you're a beginner, those 3ft to 4ft days are fine, but once it pushes over 5ft from the 8th onwards, it gets a bit more challenging. Over 7ft on the 10th, that's expert territory. Overall, Wednesday the 9th afternoon is your window.

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.
