The Lowdown
Alright folks, Rusty here with a look at what's coming down the line for us. We've got a run of surf ahead, so let's get into it.
The first proper swell shows up on Monday afternoon, the 14th of September, at Etang-Salé. This is a reef setup that needs a bit of respect, only for the advanced crew. We're looking at a solid 5ft SW groundswell with a period of 13 seconds, and the wind is set to be offshore from the SSE at 19 mph, so the face will be clean. The water’s sitting at 76°, which is a touch warmer than you'd expect for this time of year. The combined energy is moderate at best (886), and honestly, the conditions are described as marginal, so it’s a bit of a dodgy one to kick things off.
Tuesday morning the 15th gets a lot more interesting. The swell drops a hair to 5ft but the period jumps to a very long 18 seconds from the SSW. That’s proper groundswell. The combined energy spikes right up (2240). Wind is a strong 25 mph offshore from the SE, so it’ll be clean, but paddling out will be a real workout. Tuesday afternoon looks slightly better with a 6ft, 17-second swell and a more manageable 16 mph offshore breeze. Still a bit hairy.
Now, the standout window. Wednesday the 16th is the real deal for experienced surfers. We’re getting a 10ft S swell with a 15-second period. That’s a lot of water moving. The combined energy is massive (4611 in the morning, 4032 in the afternoon). Offshore winds from the SE at 12 mph will keep it lined up and clean. This is big, powerful surf. If you’re not an expert, stay on the beach for this one.
Thursday the 17th is a treat. The swell drops to a still-chunky 7ft from the south, but the wind goes glassy in the morning – dead calm. That’s about as good as it gets for clean conditions. The period is 13 seconds, so there’s plenty of push. The combined energy is still solid (1476). This is the pick of the week for anyone who can handle a solid 6ft reef break.
The surf settles down from Friday the 18th through to Sunday the 21st, with clean, waist-to-chest high waves hanging around. Winds stay offshore or light, and the conditions look fun but not epic. Energy levels are moderate to strong (between 624 and 1115). A good run of consistent, user-friendly waves for the intermediate crew.
We hit a bit of a lull from Monday the 22nd of September onwards. The swell drops off, winds get messy and cross-onshore, and the conditions turn marginal for a few days. It picks up again on Wednesday the 23rd afternoon with a clean 4ft SSW swell, but it’s not the same power.
The next real highlight comes on Thursday the 24th afternoon. The swell jumps to 4ft from the SSW with a very long 16-second period, clean conditions, and the combined energy is strong (1161). A nice one for the end of the month.
Then Friday the 25th is another standout. The swell builds through the day, hitting 8ft by the afternoon from the SSW, period of 13 seconds, and a clean 16 mph offshore wind from the SSE. The energy is high (2039). This is another session for the experienced crew only – that size at a reef break with power is serious.
Saturday the 26th and Sunday the 27th hold some size, with 7ft to 7ft swell and offshore winds, but the conditions get a bit fresh with the wind speed, making it a battle. Monday the 28th and Tuesday the 29th see the swell fading, with some glassy conditions on the Tuesday morning offering a small, clean end to the run.
All in all, the standout here is clear. Wednesday the 16th of September is the big one for the experts, with that 10ft, long-period S swell and clean offshore wind. For the slightly smaller but glassy perfection, don't miss Thursday the 17th morning.
Stay safe out there.

Information about the Etang-Sale Surf forecast
The above surf forecast table for Etang-Sale provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Etang-Sale can be found by selecting the local surf guide option on the grey menu. Our Etang-Sale 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 (Etang-Sale) 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 Etang-Sale 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.
Etang-Sale is 8 km (5 miles) from Saint-Louis. If you plan a holiday in Réunion Island, look for hotels and other accommodation in Saint-Louis. Saint-Louis has rooms for a wide range of budgets as well as car hire and transport links.
