The Lowdown
Oi, Rusty here. Grab your board and let's get into it. The next 16 days are looking proper for Etang-Sale, a consistent reef setup that's exposed and loves swell from the SSW. The water is sitting at 77°, which is a touch warmer than normal for this time of year, so you might get away with a thinner suit.
We start off Wednesday the 19th with small, clean lines. The morning is a bit average with a cross-on breeze, but it cleans up in the afternoon and turns glassy. Swell is a modest 3 ft from the south with a period of 11 seconds, but the energy is weak (358). It's a good one for a longboard or a funboard to get the arms working.
Thursday the 20th is a real treat. Glassy conditions all day, with a long-period groundswell of 2 ft from the SW rolling in at 16 seconds. The energy is moderate (443). That long period means the waves will have shape and power for their size, and the glassy wind makes it a dream session. Best for a high-performance board.
Friday the 21st builds a bit. The morning is messy with a cross-shore breeze, but the afternoon turns clean with a cross-off wind. Swell hits 4 ft from the SW at 14 seconds, and the energy is moderate (817). A solid afternoon session.
Saturday the 22nd and Sunday the 23rd see the swell jump up to 6 ft and then 8 ft from the SW. The wind is light cross-on, so it's a bit lumpy. The energy is strong (1188 to 2554). This is getting into the realm where it's good for experienced surfers, but the conditions aren't pristine.
Monday the 24th is a standout. The morning is glassy, with a solid 8 ft swell from the SSW at 14 seconds. The energy is very strong (2573). The wind is dead calm, making it clean and offering excellent surf for experienced surfers. The afternoon turns onshore, so get out early.
The following week has a mix. Tuesday the 25th and Wednesday the 26th drop in size but keep some energy. Thursday the 27th and Friday the 28th are the big hitters. A massive SSW groundswell arrives, with heights of 13 ft to 15 ft and a period of 20 seconds. The energy is immense (11,647 to 12,886). However, the wind on Thursday is a near gale, making it near impossible to paddle into. Friday the 28th is the one to circle. The wind is a moderate offshore from the SE, with a 13 ft swell at 16 seconds. The energy is huge (8804). This is exceptional surf for expert surfers only. The wave comment says "exceptional surf conditions for expert surfers" - this is a serious session for the brave.
After that, the swell drops but stays consistent. Saturday the 29th still has 10 ft with a gentle offshore, and Sunday the 30th has 6 ft. The last few days of the month and into September bring smaller, cleaner waves with offshore winds, perfect for a variety of abilities.
The real standout is Friday the 28th of August. The consistent Etang-Sale reef will be firing with a massive 13 ft SSW groundswell and a moderate offshore SE wind. The energy is colossal (8804). This is a day for experts only. The second best is Monday the 24th of August, with glassy conditions and a solid 8 ft swell.
Overall, a solid run of surf. A few days of small stuff to start, then a big push in the second week. Keep an eye on the 28th.
Rusty.

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.
