The Lowdown
Alright, Rusty here, looking at the lineup for the next couple weeks.
We've got a bit of a slow burn to start, but the back half of the forecast is where the real meat is. You gotta be patient and pick your days, because the wind is going to be a factor.
Early on, right at the end of August, we get a big wall of swell, about 13ft from the SSW, but it's blowing a strong 22 mph offshore wind. It's clean, but it's actually gonna be a battle to paddle into. Not a wave for the faint of heart. That drops off quick, and then we hit the doldrums.
From the 1st of September through the 4th, the swell just disappears. We're talking ankle-snappers of 2ft to 3ft with weak energy. There's a glassy morning on the 3rd, but it's barely a ripple. It's a flat spell, plain and simple. A real quiet period.
Now, for the one you've been waiting for. Circle Monday, the 11th of September. This is the big one. We get an exceptional pulse of SSW groundswell, 12ft, with a super long 18-second period. The energy is massive. The wind is a gentle 9 mph cross-offshore from the S. That's perfect for Etang-Sale, an advanced reef break. This is going to be a serious, clean, heavy session. Experts only. That's the day. The day before, the 12th, also looks really good with clean 8ft to 8ft swell, but that Monday is the standout.
Also worth a look is the morning of the 8th of September. It's glassy with a 10ft SSW groundswell and a super long 19-second period. The energy is off the charts. That is a world-class window for experts, but a swell that long can be unpredictable and shifty on the reef.
The rest of the second week keeps some solid swell, especially around the 12th, but the wind goes a little more cross-offshore. Still clean, but not as perfect as the 11th. The 13th has a cleaner, smaller swell with a moderate offshore – a good one to finish on.
So, to sum it up: the first week of September is mostly a write-off. Save your energy. But lock in that window from the 8th, and definitely the 11th of September. That's when Etang-Sale turns on with proper, heavy, clean groundswell. Don't sleep on it.

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.
