Etang-Sale Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into what’s cooking at Etang-Sale (Réunion) for the next couple of weeks. We’ve got a slow start, but there’s a proper pulse of energy coming through.

It’s quiet to kick things off. Tuesday the 25th is a write-off, with a messy 6ft cross-on swell and weak energy (980). Wednesday the 26th morning is still pretty average, but by the afternoon of Wednesday the 26th, things turn. The wind drops to glass, and we get a clean, long period 4ft SSW groundswell rolling in. The energy jumps right up (1701), and the water is a touch warmer than normal at 77°. This is a nice little intro session for the experienced crew—plenty of shape in the water.

Thursday the 27th is where it starts getting serious. Morning sees a solid 10ft SSW groundswell at 17 seconds with clean cross-off winds. The energy is pumping (5721). That’s big, expert-only territory, but the quality is there. The afternoon pushes up to 12ft—still clean, but you need your wits about you.

The standout window for the strong paddlers is Friday the 28th and Saturday the 29th. Friday morning delivers a 13ft SSW swell with solid offshore SE winds, energy is massive (9139). It’s clean but that size and period (16 seconds) means it's heaving. Friday afternoon gets even bigger to 15ft with strong offshore winds—cleanish but a real battle to get out. Saturday stays in that 13–12ft range, still offshore. This whole run is for the experts only. The swell direction (SSW) matches up perfectly with what this reef likes.

By Sunday the 30th, it drops to a more manageable 8ft S swell in the morning with gentle offshore winds and good energy (3531). The afternoon goes glassy with a 7ft SSW swell—clean, lined up, and much more inviting. That’s a quality day for the experienced surfer.

Monday the 31st is a bit of a mixed bag. The morning is glassy and clean with an 8ft ESE short period (9 sec) swell. It’s surfable, but the direction isn’t ideal for the reef. The afternoon gets a cross-on breeze which messes it up a bit.

Then we hit a flat, quiet patch from Tuesday 1st September through to Thursday 3rd. Swell drops below 3ft, energy is very weak (under 340). Absolutely nothing worth paddling for.

Things start to stir again on Friday 4th September. The afternoon brings a clean, offshore 6ft SW groundswell with excellent energy (2061). A really good session for experienced surfers—that long 18-second period will have some push.

Saturday 5th September sees a similar setup, with the afternoon offering a clean 6ft SW swell and offshore winds. Good, solid surf.

The final call of the window is Monday 7th and Tuesday 8th September, but be careful what you wish for. Monday afternoon predicts a massive 13ft S swell with strong offshore wind, but it’s flagged as potentially too big for the break. Tuesday morning is an even bigger 16ft SSW swell—that’s legitimate big-wave territory. The energy is off the charts (over 15,000). Only the real chargers with big-wave gear should even look at it. Tuesday afternoon drops back to a more manageable—but still heavy—15ft.

If you’re looking for the absolute best on offer with a mix of size, quality, and manageable conditions, Sunday 30th August (morning into the glassy afternoon) and Friday 4th September afternoon are the standouts. Clean, solid swell, right direction, and you won’t be fighting for your life.

Rusty.
