The Lowdown
Hey, Rusty here. Let’s take a look at what’s cookin’ at Etang-Sale.
Water temp is 77° – a touch warmer than usual for this time of year, so you might be alright in a spring suit. The forecast starts quiet, but don’t let that fool you – there’s plenty of swell coming.
First real surf hits Thursday the 20th of August. It’s small, 0.7m from the SW, but the period is a solid 16 seconds – that’s proper groundswell. On a reef break, that long period will wrap in real nice. Combined energy is moderate at 443. With a light 10 km/h offshore breeze from the south, it’ll be glassy. Thursday afternoon gets even better with 15 km/h offshore from the SE. Clean, small, and no crowd worries – this is a top pick for a mellow session.
Friday the 21st of August, the swell picks up to 1.3m from the SW, 14-second period. Morning has onshore wind, but the afternoon turns it on with a super light 5 km/h offshore from the SE. Clean conditions on a rising swell. Good session for anyone comfortable on a reef.
Saturday the 22nd and Sunday the 23rd of August, the swell builds to 1.8m then 2.5m, but the wind goes cross-on from the west. Combined energy hits 1188, then 2590, so there’s power, but the surface will be lumpy. Rideable for stronger surfers, but not the cleanest.
The standout is Monday the 24th of August. The swell sits at 2.5m from the SSW, 14-15 second period, and by the afternoon the wind goes glassy – dead calm from the south. Combined energy is 2278. This is excellent, powerful surf for experienced surfers only. Big, clean, and heavy – if you’ve got the skill, this is the one to chase.
Tuesday the 25th and Wednesday the 26th see the swell drop to 1.6m to 1.8m. Winds turn offshore again, especially Wednesday afternoon with a moderate 20 km/h from the SSE. Clean enough for intermediates.
Then it gets serious from Thursday the 27th of August. Morning brings 3.0m from the SSW, 16-second period, with fresh 35 km/h offshore wind from the SE. Combined energy is 4186. By afternoon, it’s 4.0m with a 19-second period – super long period – and a near-gale 50 km/h offshore wind. Combined energy is 10119. This is massive. Experts only. Huge, powerful waves with wild wind.
Friday the 28th of August stays massive – 4.5m morning, 4.0m afternoon – with strong offshore winds. Combined energy over 10,000. Again, for experts only. The swell slowly eases through late August and into early September, with many sessions holding clean offshore winds.
The last solid highlight is Friday the 4th of September. After a quiet spell, we get 1.4m SW swell, 15-second period, with clean winds. Combined energy is 1072. Fun, clean waves to finish the run.
Bottom line: experts target Monday the 24th for the clean heavy stuff, and the 27th-28th for the extreme big-wave action. Everyone else, the cleanest and most fun sessions are Thursday the 20th and Friday the 21st of August afternoons.
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.
