The Lowdown
Alright, let’s get into it. The 16-day window ahead is a real mixed bag. The bulk of the action is at Etang-Sale, a solid reef break that really needs the right conditions to shine. The water’s sitting at 77°, a touch warmer than usual for the time of year, which is always a nice bonus.
The first few days are a bit of a warm-up. Sunday, the 22nd, has some swell but the wind is a bit messy with a cross breeze and the quality is marginal – not really worth getting too excited about. Monday, the 24th, that’s when we start to see things clean up. The early morning brings a clean, cross-off breeze with an 8ft swell from the SSW at a juicy 15-second period, and the afternoon turns proper offshore from the SE. The combined energy is strong, sitting well into four-digit numbers (2846 / 2311), so you’ve got proper oomph behind those waves. This is advanced territory; the size and power are not for beginners.
Tuesday and Wednesday of that first week are more mediocre – the wind turns cross-on and the swell backs off a bit. It’s surfable but nothing to write home about. Then we get into the real highlight of this outlook.
The standout session is Thursday the 27th. The morning is exceptional for experienced surfers. We’ve got a deep 10ft swell from the SSW with a very long period of 17 seconds, and a clean cross-off breeze. The combined energy hits a massive 5346 – that’s serious power. This is a true groundswell, perfect for a reef like Etang-Sale. The sets will be pulse-y and lined up, but you need to know what you’re doing; this size is well over 8ft, so it’s experts only. The afternoon stays clean but the wind picks up a notch.
The tail end of the first week into the weekend (the 28th and 29th) gets even bigger – we’re talking 13ft to 15ft swells, but the wind cranks up to a strong 40-45 km/h offshore. That’s a proper battle to get out and even harder to control your board. The energy numbers are monstrous (10,000+ region), but that wind will make paddling a nightmare. Kite surfers would have a field day, but for regular paddle surfing, it’s only for the absolute elite.
Things settle down into the following week. The 30th and 31st still have solid swell in the 7ft to 12ft range, with clean offshore breezes and even some glassy conditions on the Monday morning. It’s still good, but not quite the magic of that Thursday morning.
Then the surf completely drops away from the 1st of September through to around the 5th. That’s a proper five-day gap of tiny, weak waves – energy values fall to under 500, with swell heights barely hitting 3ft. It’s flat spells, that’s normal for this area.
The second highlight, but a long-range call, is Sunday the 6th through Monday the 7th. Another big SSW groundswell reappears – 7ft to 8ft, with a 20-second period on the Sunday morning, which is incredibly long. The combined energy rockets back up to 3501. Winds look favourable (cross-off and offshore). This is a promising window but it’s over a week away, so keep an eye on it; the details could change. The Monday (7th) still has size but the wind goes light cross-on, so it won’t be as clean.
Bottom line: Thursday the 27th is your best bet for epic, clean, powerful waves. After that, keep your fingers crossed for the weekend of the 6th-7th.

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.

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.
