The Lowdown
Alright, let’s get straight into it. This is the outlook for Les Conches, and I’ll be honest with you—it’s a tough stretch. There’s barely a whisper of decent surf in the whole 16-day window.
We’re starting off on Wednesday the 26th of August, and straight away it’s a letdown. Tiny waves, mostly below 2ft, with a weak WSW swell and short period. The water temp is sitting at 70°F, which is about a degree warmer than normal for this time of year—nothing crazy, but it’s a nice little touch if you’re just floating around. Problem is, there’s no push. The energy is pathetic—single digits to low double digits (18 energy units on Wednesday morning).
Thursday the 27th and Friday the 28th are a bit of a tease. Swell bumps up to 2ft–4ft, but the period is rubbish—mostly 5 to 8 seconds—so it’s weak and wonky. Winds are cross or cross-on, and the surf quality is poor. You’re better off staying home.
Then we hit Friday afternoon the 28th: the biggest swell of the outlook shows up at 7ft from the SW, period a middling 8 seconds. Combined energy jumps to 478 (moderate). But the wind is howling onshore from the WSW at 25 km/h (16 mph), so it’ll be a messy, blown-out wall of whitewater. That’s expert-only territory and even then, it’s ugly. Unless you’re into kite surfing in that onshore wind, there’s nothing for a paddle surfer here.
Saturday the 29th through to Tuesday the 1st of September is a mix of onshore winds and dropping swell—5ft down to 3ft—with no clean windows. There’s a long-period groundswell on Sunday the 30th (11 seconds) but it’s ruined by 30 km/h (19 mph) onshore winds. Energy on Sunday afternoon hits 964, but it's wasted.
Wednesday the 2nd and Thursday the 3rd see a tiny lift in hope. Thursday morning the 3rd of September finally gives us a tiny window: 2ft from the west, period 8 seconds, and light offshore winds from the east at 15 km/h (9 mph). It’s surfable but very ordinary—scoring just a 1 out of 10 internally. Clean lines, but barely enough water to get a proper ride. If you’re a beginner with a longboard, you might get a couple of ankle-biters.
Friday the 4th through to Wednesday the 9th of September is mostly flat or waist-high at best, with a few clean moments but tiny energy (mostly below 100). Saturday morning the 5th of September is glassy—0 km/h wind—but only 2ft at 10 seconds period. It’s clean but small. Not a standout by any stretch.
The best of a bad bunch? Honestly, there’s no true standout. The closest to a recommendation would be Thursday morning the 3rd of September at Les Conches, with that clean offshore, tiny but rideable 2ft swell. Or maybe Saturday morning the 5th of September, glassy conditions but again small. If you’re desperate and have a log, those are your moments. Otherwise, it’s a long gap of poor surf with no real fire.
Expect crowds sometimes here, but honestly, with this quality, the beach should be quiet.
It’s a rough run, but forecasts can change. Hang in there.

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.
