The Lowdown
Alright, Rusty here, and I’ve had a good look at what’s on the cards for the next couple of weeks. Honestly, it’s a tough stretch. We’re looking at a long, long gap with hardly anything worth paddling out for.
Over at Bagasse (reef), the first hint of anything surfable doesn’t show up until Friday morning, the 18th of September. Even then, it’s not a winner. The swell is only 4 feet from the east, with a short period of 7 seconds, and the combined energy is moderate at 311. The wind is a cross-offshore breeze from the east at just 9 mph, which keeps the surface clean, but the wave quality is described as only "expect good surf conditions" – nothing to write home about. Before that day, from today right through until the 17th, it’s all junk. We’re talking about a solid 5-day gap of poor surf, mostly from easterly cross-off winds but with swell periods under 9 seconds that just don't have any punch. The energy readings are mostly weak to moderate (below 200), and the wave comments are all "poor surf conditions." Not a single score worth mentioning.
After that Friday morning blip, it drops right back off. From the 18th afternoon all the way through to the 28th of September – that’s another 10 days of "poor surf conditions." The swell sticks around the 1 feet to 4 feet range, mostly from the east, but the periods are short (6 to 9 seconds), and the energy levels are low, often under 100. Winds are mostly cross-off or cross-shore, with a few instances of moderate cross-chop. There’s a moment on the 23rd of September (Wednesday afternoon) where the conditions are described as "surfable waves but very ordinary," with a tiny 2 feet swell from the east, but that’s about it.
So the only time to even *think* about it is the morning of Friday the 18th. The water temperature is a warm 85°F, which is pretty much normal for this time of year.
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.
