The Lowdown
G’day, Rusty here. I’ve given Bagasse (reef) a thorough look, and I’ll level with you – this forecast is a struggle. The 16-day window is mostly a loss. The first real chance to even think about a paddle doesn’t show up until Monday, the 24th of August, and even then it’s barely worth it. The wind is our enemy for most of it. The wave energy is mostly weak to moderate (from 272 down to 125), so there’s no grunt behind it.
Water temp is 29°, which is dead average for the season, so no surprises there.
The only day that gets my pulse up is Saturday, the 29th of August. That morning we see a 2.5m swell from the ENE with a period of 8 seconds, and the combined energy hits 881 – that’s moderate energy, finally something. But the afternoon is the true standout. The swell jumps to 3.0m from the east, the period stretches to 9 seconds, and the energy rockets to 1761 – that’s strong energy. Now, 3.0m is big; that’s expert-only territory. The wind is cross-offshore, so the surface will be clean, but the size means it’s not for everyone. This is your one and only shot at something real, but with that size and a reef bottom, it might honestly be more suited to the kite surfers than paddle surfers if the wave quality gets tricky.
After that, it fades fast. Monday, the 31st of August, gives us a weak 1.4m wave with light winds, but it’s just marginal. By September, the swell is barely 1.0m with energy down to 124, and the wind is either light and onshore or cross. It’s a dry spell straight through the first few days of September. Nothing doing.
So, the bottom line is: the whole 16 days is a flat patch except for one powerful burst on Saturday the 29th. That 3.0m east swell in the afternoon is the only option, and it’s for experts only. Save your energy otherwise.
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.
