The Lowdown
Alright folks, Rusty here with the 16-day outlook for Les Conches. It’s gonna be a real test of patience, so let’s get straight into it.
Honestly, the first week and a half looks pretty grim. The opening days – Thursday 20th and Friday 21st of August – are dominated by weak, messy, onshore choppy waves. Swell energy is weak, with values around 164 to 331 (combined energy), and the wind is working against us. Saturday 22nd morning offers a little something: clean, gentle offshore ENE wind at 9 mph, but the swell is tiny at 2 ft from the west. It’s surfable but very ordinary. Then we hit a long dry spell. From Saturday afternoon all the way through to Wednesday 2nd September morning, the waves are either too small, blown out, or just plain poor. That’s over a week of very little worth paddling out for.
The real standout window, and I mean the only true highlight, arrives on Thursday 3rd September. The early morning looks promising. We’ve got a 5 ft swell from the WSW, period around 9 seconds, and a gentle offshore breeze from the east at 9 mph. The combined energy is moderate at 367. The forecast says “expect good surf conditions,” and with that offshore wind, it should be clean and lined up. This is the best on offer. Friday 4th September morning is also worth a mention – glassy conditions with a 5 ft swell from the west at 10 seconds, energy at 496. It could be fun, but it’s a little less certain.
Les Conches is a beginner-friendly, fairly consistent spot, exposed to the swell, best with a WSW direction. The water temperature is about average for this time of year, nothing unusual. For most of the 16 days, the wind is just not on our side, but if you can wait, that Thursday morning window is the one to aim for.
Rusty.

Information about the Les Conches Surf forecast
The above surf forecast table for Les Conches provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Les Conches can be found by selecting the local surf guide option on the grey menu. Our Les Conches 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 (Les Conches) 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 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. 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.
