The Lowdown
Alright, this is Rusty. Let’s break it down.
We’ve got a solid run of surf building through the forecast window at Etang-Sale. It starts off a bit lumpy and messy this weekend, but hang in there. The water temp is sitting around 25°, which is a touch warmer than normal for this time of year, so you might feel that difference in the water.
Kicking off Saturday the 15th, we’re looking at a serious 6ft S swell but the wind is cross-on, light though. It’s got a very long 20-second period, which is a proper groundswell, but for a setup like Etang-Sale – a reef break – that long period can actually make the waves a bit too lined-up and tricky. The combined energy is high (5359). By afternoon it jumps to 8ft, still S, wind turns onshore light. It’s going to be a bit of a battle. Sunday the 16th stays big, 8ft from the SSW, 16-second period, but with cross-onshore and then cross winds, the surface won’t be clean. This first weekend is really for experienced crew only.
Monday the 17th sees the swell back down to 5ft, but by the afternoon the wind goes cross-off and clean. That’s the first real glimmer of quality. Tuesday the 18th drops a little more, 4ft, but again afternoon sessions have light cross-off wind and clean conditions – small but rideable.
Now, the true standout window opens up from Thursday the 21st. By the morning we’ve got 4ft from the SW, period 14 seconds, and a clean offshore wind from the SE at 15 mph. The energy is building (695). This pattern locks in through Friday the 22nd with 6ft, same direction, same offshore wind, energy climbing over 1300. It’s excellent quality for experienced surfers. That’s where you want to be.
But the real big show? That’s Sunday the 23rd of August. Swell jumps to 13ft from the SSW, huge energy (8611). Only for experts – that’s big, powerful reef surf. The wind is onshore and cross-onshore that day, so it will be lumpy and challenging. Monday the 24th stays big at 10ft but goes clean with offshore wind – that could be the best combination of size and shape for the experienced.
And then, a week later, Thursday the 27th of August looks like the absolute peak. 13ft from the SSW, 17-second period, energy at 8730, light offshore wind – clean and powerful. That is a day for expert surfers only, but it’s the kind of session you’d drive a long way for. The run continues big into the weekend.
Etang-Sale is consistent and exposed, but it’s a reef, and when the swell gets above 8ft it’s definitely not for beginners. The best bet for the average experienced surfer is the window from Thursday 22nd through that weekend, where you get overhead waves with clean offshore winds. For the thrill-seekers, the 27th is the one to circle on the calendar – but keep an eye on the forecasts as we get closer.

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.
