The Lowdown
Alright, Rusty here. I’ve got one spot on the map for the next couple of weeks: Les Conches. And I’m gonna be honest, it’s a bleak outlook.
For the first week and a half, it’s a whole lot of nothing. The wind is all over the place, mostly blowing onshore or cross-onshore, and the swell is tiny and weak. You’ll get a few glassy mornings on the 10th and 12th, but the swell is barely 1.6ft with weak combined energy (42 and 36) – it’s surfable, but just barely. Water temp is about average for this time of year, nothing special.
The real problem is the wind. From the 7th to the 15th, it’s mostly howling out of the west or northwest, making it a choppy, messy disaster. The swell is just too small and weak. There’s a brief clean window on the morning of the 16th with a cross-offshore breeze, but the swell is still only 2ft, so it’s barely a ripple.
The only real light at the end of the tunnel comes on the 17th of September. Thursday morning, we finally get some life. The wind swings offshore from the ENE, and the swell bumps up to 4ft from the west. The combined energy (477) is moderate, and the forecast is for good surf conditions. This is the standout. It’s a clean, moderate offshore breeze, and the break is exposed to the swell. The wave period is 10 seconds, so it’s got some push. The difficulty is for beginners, so it won’t be too heavy, but it’s the best we’re going to get. The 18th also looks promising with a clean morning and a 3.6ft west swell.
After that, it fades out again. The 21st and 22nd have a bit of offshore wind, but the swell is tiny. The 22nd has a 2.3ft swell with a period of just 7 seconds – weak and short period, not worth your time.
So, to wrap it up: the first 9 days are a wash. If you’re desperate, the 17th and 18th are your only real chance. The morning of the 17th is the pick of the bunch. Otherwise, it’s a lot of waiting. Forecasts can change, but right now, this is a tough run.

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.
