The Lowdown
G’day, Rusty here, and I’ve got a good look at what’s coming up for Etang-Salé over the next couple of weeks.
The first week kicks off with some clean, fun-sized surf, but the real standout is a proper pulse of energy that hits around the 20th and 21st of July. After that, things get a bit wild and woolly into the second week, with some serious size but tricky conditions.
Alright, let’s start with the now. Friday 17th July is a bit of a mixed bag. The morning has a small 3 ft S swell with a period of 17 seconds, but the wind is cross-on at 6 mph, so it’s a bit messy. The afternoon cleans up nicely with a cross-off breeze and a 5 ft S swell, making for a cleaner session. The water temp is a balmy 76°, which is about average for the time of year.
Saturday 18th and Sunday 19th July keep the trend going with clean, cross-off winds and swells around 3 ft to 4 ft from the S and SSW. The combined energy is moderate (382 to 574), and the waves will be tidy but not huge. Good for a cruise.
Now, the standout window arrives Monday 20th and Tuesday 21st July. Monday morning is glassy, with a 8 ft SSW swell and a period of 14 seconds. The combined energy is strong at 2316, and the conditions are described as excellent for experienced surfers. This is the pick of the forecast. Tuesday morning holds onto that quality with a 6 ft SSW swell, glassy conditions, and strong energy (1161). The wind is glassy or very light, so the surf will be clean and powerful. These are the days to clear your schedule.
Wednesday 22nd through Friday 24th July sees a shift to stronger offshore winds from the SE, blowing at 16 to 22 mph. The swell holds around 5 ft to 3 ft, with clean faces but a bit of a fresh breeze. The combined energy is moderate to strong (716 to 1060). This is more for the dedicated crew who don’t mind a bit of wind.
The weekend of 25th and 26th July eases off. Saturday morning is glassy again with a 4 ft SW swell, and the energy is moderate (672). Sunday 26th July brings a longer-period swell of 20 to 21 seconds from the SW, but the wind is cross-on, making it marginal. The energy is strong (1323 to 2028), but the conditions won’t do it justice.
Then we hit the big stuff. Monday 27th July sees a 10 ft to 12 ft SSW swell with a period of 17 to 18 seconds and combined energy through the roof (7044 to 7515). This is exclusively for experts, and the wind is onshore or cross-on, so it’s a messy, heavy beast. Not for the faint-hearted.
Tuesday 28th July is a better bet for the brave. The swell is still 10 ft SSW, but the wind goes offshore at 16 mph, cleaning it up. The energy is still massive (4948), and the conditions are excellent for experienced surfers. This is the second standout, but only for those with serious skills.
From Wednesday 29th July to Friday 31st July, the swell drops a bit to 7 ft to 8 ft, but the wind stays strong offshore at 19 to 25 mph. The energy remains powerful (2827 to 3608), but the fresh to strong breeze makes paddling a battle. It’s clean but hard work.
The outlook wraps up on Saturday 1st August with a drop back to 4 ft SW swell, moderate offshore winds, and moderate energy (672 to 864). A more relaxed session to finish.
So, the clear standout is Monday 20th and Tuesday 21st July for the best combination of size, clean conditions, and quality. The second standout is Tuesday 28th July for the big-wave crew, but only if you’re experienced.
Rusty.

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.
