The Lowdown
Alright, let’s have a look at Etang-Sale. This is a reef break that’s wide open to the ocean, so when the swell shows up, it can get real good. The water’s sitting at 77°, which is a touch warmer than usual for this time of year, so you’re fine in a shorty or boardshorts.
The first surf rocks up on Thursday morning, 13th August. It’s a small one, 4ft from the SW, with a 13-second period. The wind is a light offshore breeze, so it’ll be glassy. The combined energy is moderate (552). It’s a gentle start.
Thursday afternoon picks up a little, 4ft, still SW, with a 12-second period, and the wind goes glassy. Real clean. The energy is building (766).
Friday morning, 14th August, is where it gets interesting. The swell is 6ft from the SW, with a 13-second period, and the wind is glassy. The energy is strong (1447). This is a session for the experienced crew.
Friday afternoon is a bit of a letdown. The swell is 6ft from the SSW, but the wind goes onshore from the NW, messing it up. The energy is high (2093), but the surface is rough.
Saturday morning, 15th August, is a serious groundswell. 6ft from the south, with a 20-second period. That’s a very long period, so it’s powerful, but it might break a bit straight on this reef. The wind is offshore from the WNW, so it’s clean. The energy is massive (5359). This is a standout for the experts.
Saturday afternoon is the one to circle. The swell hits 10ft from the SSW, with an 18-second period. The wind is a light cross-offshore breeze. The combined energy is exceptional (6970). This is for experts only, no doubt. It’s the best on offer.
Sunday morning, 16th August, is still big, 10ft, but the wind is cross-onshore, so it’s a bit bumpy. The energy is still very strong (4203). Only for the hardcores.
Sunday afternoon drops to 8ft, but the wind is cross-shore, so it’s not clean. The energy is still strong (3499).
Monday, 17th August, the swell drops to 5ft with a 16-second period. The morning is offshore, and the afternoon is clean with a cross-offshore breeze. The energy is moderate (1776). A solid day.
From Tuesday, 18th August, through to Thursday, 27th August, it’s a consistent run of waist to head-high SW and SSW swells, periods of 11-16 seconds. The winds are mostly offshore or glassy, so the conditions are good. The energy is moderate to strong (856-1509). Good, consistent surfing.
The standout in the second week is Friday morning, 28th August. Swell is 7ft from the SSW with an 18-second period, the wind is glassy, and the energy is huge (2983). This is a real groundswell. It’s a long-range call, but it looks promising.
This spot is for advanced surfers, especially when the swell gets over 8ft. It’s a consistent wave, but crowds can show up sometimes, so keep that in mind.

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.
