The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for Etang-Sale. Let’s cut through the noise.
Right, so the first week gets off to a slow start. Monday the 10th is pretty average; there’s some swell, but the wind is onshore or cross-onshore, and the conditions are just messy. Not worth getting excited about. You’ve got a bit of a wait for the real magic.
Tuesday the 11th is where things turn around. We’ve got a 4ft to 4ft SW groundswell with a long 14-15 second period. But the real story is the glassy conditions. Tuesday morning is dead calm, glass-off, and by Tuesday afternoon it’s still glassy. That’s the kind of clean, lined-up reef setup that makes you want to call in sick. The water temp is about 77°F – roughly 4°F warmer than usual, which is a nice little bonus for the skin.
Wednesday morning the 12th is also glassy and clean, but the standout of the whole first week is Thursday the 13th. We’ve got 4ft to 4ft SW swell, and both morning and afternoon sessions are glassy. It’s not huge, but it’s pure. The wave energy is moderate but well-organized. If you can surf a reef, this is as clean as it gets.
Friday the 14th has a sneaky good afternoon. The morning is cross-on, but by the afternoon, it’s glassy with a 4ft SW groundswell running a very long 21-second period. That’s a real groundswell pulse. The energy is strong, and it’s one of those sessions where the sets will be defined and the paddle-out easy between them.
Now, the second week – hold on to your board. Saturday the 15th starts to get bigger, with 5ft to 8ft S swell, but the wind is cross-on, so it’s a bit lumpy. But from Sunday the 16th, we’re in business. The morning has a 7ft S swell with offshore wind (SE at 6 mph). The afternoon is even better: 8ft SSW groundswell at a solid 16 seconds, with offshore ESE wind. That’s big, clean, and powerful. The wave energy is very strong. This is expert territory – no place for beginners.
Monday the 24th and Tuesday the 25th are the absolute best of the whole outlook. Monday the 24th morning has 8ft S swell with a 17-second period and gentle offshore wind. The afternoon jumps to 12ft S swell with a fresh offshore wind (18 mph). That’s a serious, powerful groundswell. Tuesday the 25th stays strong, with 8ft and 8ft S swell and clean offshore winds. This is the sort of swell that will be working perfectly on the reef, offering long, heavy walls for experienced surfers only.
Crowds can be a factor at Etang-Sale, but when the surf is this high quality and the winds are offshore, it’s worth dealing with. The break is consistent and exposed to the SSW, which matches the swell direction perfectly.
So if you’ve got one window to clear your schedule, it’s the whole run from Sunday the 16th through Tuesday the 25th, but the absolute standouts are Sunday the 16th afternoon and Monday the 24th. That’s the gold.
This is Rusty, signing off.

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.
