The Lowdown
Alright, let’s break down what’s happening for Les Conches over this 16-day stretch. Honestly, for the first week and a half you won’t find much to write home about unless you like flat spells with a touch of bump now and then.
The water is sitting at about 71°, which is a touch warmer than normal for this time of year, staying about 4° above what you’d expect in an average autumn.
Right now, starting Saturday morning (12th September), the waves are tiny, barely 0.5ft, with weak energy at only 33. Glassy wind but nothing to surf. Sunday morning (13th September) gives you a 0.4ft pulse with a better 12-second period, but still only 93 combined energy. Clean but small.
Then things get pretty drab. We’re talking days of choppy, cross-onshore wind on tiny waves. Wednesday morning (16th September) sees a 1.0ft bump but it’s only 8-second windswell with energy at 148 and a cross-shore breeze. Not really worth suiting up for.
There’s a long patch of poor surf quality running right through the middle of the outlook. You really have to wait until the third week.
The standout arrives Monday 21st September afternoon. Swell hits 0.8ft from the west with a long 14-second period, combined energy jumping to a decent 275. The wind is light and cross-off from the north-northeast, making it clean as a whistle. This is easily the best session of the whole 16 days – small, clean, long lines. It’s a point-and-shoot affair for your longer board. Crowds can show up here sometimes so expect a few others with the same idea.
Saturday 19th September morning is also worth a look: 0.7ft, 13-second swell, combined energy 153, and a clean cross-off breeze from the northeast. It’s a good second choice.
After that, from Monday 21st onward it slowly drops back into small, choppy slop. By Sunday 27th September we’re looking at 0.9ft but with only a 5-second period – just wind bumps. Not worth your time.
So the play here is simple: aim for Monday 21st September afternoon as the best pick, with Saturday 19th September morning as a backup. The rest is mostly a flat spell with occasional clean windows.
Stay stoked and check the tides.

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.

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.
