The Lowdown
Alright, Rusty here. Let's talk about what's cooking at Etang-Sale.
Overall, we're looking at a run of pretty darn good surf, especially for the advanced crew. This is a reef break that needs a solid SSW groundswell to get going, and that's exactly what's on the menu. The water temp feels about average for this time of year, nothing too wild.
Monday morning the 10th of August kicks things off nicely. A clean 4.3ft SW swell (878 combined energy) with glassy conditions. That's a sweet combo for a Monday. The afternoon gets a bit messier with a cross-on breeze, so make the most of the morning.
Tuesday the 11th looks like a real gem. Both the morning and afternoon sessions are glassy, with a clean 4.3ft to 3.9ft SW swell. This is the kind of day where you paddle out and don't want to come back in. The 14-15 second period means it's a proper groundswell, giving you long, smooth lines.
Wednesday the 12th is a mixed bag. The morning has a cross-shore breeze, but the afternoon cleans right up with an offshore SE wind and the swell holding at 4.3ft. That's a good call for an afternoon session.
Thursday morning the 13th is another glassy winner, with a 3.6ft SW swell. Perfect for a dawny. The afternoon gets a cross-on wind, so aim for early.
Friday the 14th brings a bit more size. The morning swell jumps to 6.2ft, but the wind is cross-on. The afternoon, however, is where it gets interesting. A 3.6ft swell with a massive 21-second period and clean, cross-off wind. That's excellent, experienced-surfer territory. The long period means those waves will have serious punch and shape, but at a reef break like this, it'll be a proper barrel machine for the guys who know what they're doing.
Saturday the 15th sees a big jump in energy. The morning has a 5.6ft S swell with a 20-second period, but the wind is cross-on. The afternoon is pumping with an 8.2ft S swell and 19-second period (6621 combined energy!). That's big, powerful, and for experts only. The wind is onshore though, so it might be a bit of a battle. This is kite-surfing territory if it gets too messy for a paddle board.
Sunday the 16th is the standout for the week. Morning session: glassy conditions with a 7.5ft SSW swell and a 16-second period. That is a serious amount of juice (4025 combined energy). For an advanced surfer, that's a dream window – big, clean, powerful reef waves. The afternoon picks up even more size to 8.2ft, but the cross-on wind picks up too, so the morning is the golden ticket.
From there, the surf settles down. Monday the 17th has a 3.9ft SW swell, and Tuesday the 18th has a 6.6ft swell but with a short 8-second period, so it won't have the same shape. The rest of the week into the 20th sees the swell drop to under 3.3ft.
Then, looking way out to the 21st of August and beyond, we get a solid window of offshore winds from the SE. The 21st and 22nd see 3.9ft to 6.2ft S/SSE swells with clean, offshore conditions. The 22nd afternoon, with a 6.2ft S swell and moderate offshore wind, looks like a great call for a weekend session. The 23rd keeps the clean offshore flow but with slightly smaller surf.
The best on offer: Sunday the 16th morning at Etang-Sale. Glassy, 7.5ft SSW groundswell, 16-second period. It doesn't get much better than that for a reef break. Tuesday the 11th is a close second for a cleaner, smaller day.

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.
