The Lowdown
G'day, Rusty here. Let's talk about Bagasse. This reef break is a bit of a mixed bag for the next couple of weeks, with a real standout session on the horizon if you're willing to wait.
The water temp is sitting at 84°, which is pretty normal for this time of year.
Alright, the outlook starts with a big gap. There's nothing worth paddling out for from now until we get to the 24th of August. You'll be looking at over a week of small, weak, or messy conditions. The energy is just too low, and the wind is often cross or cross-off with a chop. It's a dry spell, plain and simple.
Now, the real action kicks off on Monday the 24th of August. The morning session is the standout of the whole outlook. We've got a solid 8 ft swell from the ENE, with a 10-second period. The wave energy is pumping at (1004), and with the wind swinging light from the ESE, it's going to be clean. The guidance says this spot loves swell from the north, and this ENE direction is a good fit. This is excellent surf for experienced surfers only, as that 8 ft is pushing into proper territory. Keep in mind, though, that this is a reef break, so it'll handle the longer period nicely.
Monday afternoon holds up well too. The swell drops a touch to 7 ft from the ENE, but we get a light offshore breeze from the south, making for clean, very good surf (761). Still one for the experienced crew.
Tuesday the 25th of August morning is still a decent option. The swell settles to 6 ft from the E, with a 9-second period and a light cross-off breeze. You'll get clean, good waves (540), but it's not the standout that Monday morning is.
After that, the energy fades. From Tuesday afternoon onward, it's back to small, weak, and ordinary conditions as we head into the end of the month. The consistency is fair, but the quality just isn't there for the rest of the run.
So, to sum it up: sit tight. The wait is long, but if you're an experienced surfer, Monday the 24th of August morning at Bagasse is your best bet by a long shot. The crowd factor is "sometimes," so you might have some company, but the quality will be worth it.
Rusty, signing off.

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.
