The Lowdown
Alright, boys and girls, Rusty here. Let’s get into it. We’ve got a solid stretch of surf ahead, but it’s gonna take a bit of patience to get to the real gold.
The first few days are a bit of a mixed bag. The swell is there, but the winds aren’t playing nice. On Thursday morning, the 13th, we’ve got some clean, fun waves at Etang-Sale (Reef) – 4ft of SW swell with a 13-second period. The energy is moderate (552), but it’s rideable. That afternoon, though, the wind swings onshore and it gets messy. Friday and Saturday are similar – a bit of size building, but the cross-onshore wind keeps things lumpy. By Saturday afternoon we’re looking at a solid 10ft, but it’s all over the place. There’s a lot of energy moving (6540), but it’s not going to be pretty.
Then we get a bit of a reset. Sunday the 16th has some overhead, powerful waves, but the wind is all over the place and it’s a bit of a wash. Not the day for it.
Now, here’s where things start to get interesting. Monday the 17th through Wednesday the 19th, we get those offshore SE winds. The swell drops a bit, back to the 4ft to 5ft range, but it’s clean, groomed, and much more your classic Andaman style. The energy is moderate, but the quality makes up for it. A couple of those morning sessions are going to be really nice with the light offshore breeze. Kooks beware, there’s still some power in the water.
We hit a small lull mid-period. Thursday the 20th is small and weak – not really worth paddling out for. It picks up a little on Friday, but it’s not until the following week that the real show starts.
And that show is on Wednesday the 26th. This is the standout. Holy smokes. We’ve got a big, powerful S swell pumping in at 15ft with a 14-second period. The energy reading is off the charts – 12972, which is about as strong as it gets. And the wind? Solid offshore. This is a serious, serious day of surf. For experts only. If you’re not comfortable in heavy, solid reef surf, this is not the day for you. This is the one you’ve been waiting for.
The day before, Tuesday the 26th, is also a great option with 11ft and offshore winds, but Wednesday is the clear winner. And even after that, Thursday the 27th holds some size and quality. The Friday after that drops off a bit, but it’s still fun.
So, overall, the window is wide open. We’ve got a few days of mediocrity in the early going, but also some clean, smaller windows. The big prize is that Wednesday. Mark your calendars.
Alright, that’s the look. Stay stoked.

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.
