The Lowdown
Alright, Rusty here. Let's size up Bagasse over the next couple weeks.
It’s a tough go for a while. The first week is pretty much a bust, with surf quality flagged as poor straight through until the end of August.
The real standout window isn't until Wednesday, August 26th, in the afternoon. You've got a 5ft swell from the East-Northeast with a light, clean cross-off breeze and barely a breath of wind. The water is a warm 84°, right where it should be for this time of year. The wave energy is moderate (419), but with those smooth conditions, it’ll be clean and fun. That’s the one to circle on the calendar.
Before that, the biggest pulse hits Tuesday, August 25th, with a 7ft swell. But it's accompanied by a fresh cross-wind and lumpy conditions – that one's a beast for experienced surfers only. The rest of the days are plagued by onshore or cross-shore winds that chop things up. Looks like a long period with only one real clean session on the 26th. A quiet run overall.
Rusty 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.
