The Lowdown
Alright, Rusty here.
Alright, let’s take a look at what’s on the cards for the Etang-Sale stretch. We’ve got a solid run of groundswell on the way, and it’s mostly an experienced surfer’s game out on this exposed reef. The water’s hanging around a touch warmer than normal for the time of year, which is a nice bonus.
It all kicks off this Friday afternoon, the 11th of September. The first real standout is Saturday the 12th. We’re seeing a clean 5ft SSW groundswell rolling in with a 14-second period, and the wind is light and clean. The combined energy is moderate (958), but the real prize is the quality of the wave and the offshore conditions.
But if you want the true standout of this whole run, you have to look at Wednesday the 16th of September. The morning is going to be pumping. We’re talking a solid 10ft of S swell with a 15-second period, and clean offshore winds. The wave energy is massive (4460). This is a serious, powerful reef wave and it’s only going to be for experienced surfers. Don’t even think about taking a foamie out there.
The Sunday the 13th is also a beauty, with 7ft SSW swell and a 16-second period, all under clean offshore winds. The energy is strong (2506). It’s going to be a great day, but it’s that Wednesday that’s got the size and the power.
We’ve got a solid run of surf right through the middle of the month. There is a bit of a lull setting in around the 19th and 20th, with the swell dropping off and cross-onshore winds. But then we see another promising window. The 21st of September has a glassy morning with 5ft SW groundswell hitting that 17-second period. It’s going to be clean and you’ll have long waits between sets, but the paddle out will be a breeze.
As we head into the final week of the month, the swell really starts to fade. There is still some 5ft swell on the 25th, but the wind is messy. By the 26th, it’s small and blown out. It looks like we’ll be looking at a few days of small, unappealing surf to close out the forecast.
Keep an eye on that Wednesday the 16th. That’s the day to clear your calendar.
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. 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.
