The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the cards for us over the next couple of weeks.
Honestly, it’s a bit of a tough stretch ahead. The forecast is showing a real lack of quality windows, with the wind and swell rarely lining up for a clean session. We’ve got a few days of flat, tiny waves to start, and then a big pulse of swell arrives, but it's going to be blown out. The standout moments are very few and far between.
The only spot in the game is Les Conches. To be straight with you, the water is sitting at a mild 72°, which is a touch warmer than normal for this time of year, so that’s a small silver lining.
The best chance we’ve got to wet a line is this coming Saturday morning, August 22. It’s not going to be epic, but it’s the best on offer. We’ll see a small 2 ft swell from the west, with a period of 9 seconds, giving weak wave energy (54). The wind will be a gentle 9 mph cross-off from the east, which will keep the surface clean. It’s surfable, but it’s very ordinary.
After that, things get grim. The wind turns onshore and stays that way for days. Then, around Thursday, August 27, a solid swell starts to build. By Friday the 28th, we’re looking at a massive 12 ft swell from the west-southwest, with a period of 12 seconds and very strong energy (2799). That’s serious power, but it’s only for experts. The problem is the wind is howling onshore at 22-25 mph, making it a total mess. The setup looks more interesting for kite surfing than paddle surfing during that blow.
We do get a bit of a reprieve on Tuesday, September 1. The morning shows a 2 ft westerly swell with a 9 mph offshore wind from the northeast. Clean and gentle. Again, it’s small, but it’s the cleanest we’ll see in that second week.
The long-range is a bit of a gamble. Saturday, September 5 morning has a 5 ft swell from the west with a 10-second period and moderate energy (551), paired with a light cross-shore wind from the northwest. That’s a promising but less certain option. It could be fun if the wind plays ball.
So, the short story: snag that tiny, clean window on Saturday morning, or wait it out for a hopeful look at that first Saturday in September. It’s a patchy run, but it won’t stay this way forever.
Rusty.

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 Les Conches 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.
