The Lowdown
Alright, Rusty here. Let's have a chat about Les Conches.
Look, I gotta be straight with you. The next two weeks are a bit of a struggle. We've got tiny waves and a lot of junk wind. From the start of the period right through until the 29th of August, it's a daily grind of small, poor surf, with hardly anything worth paddling out for. The combined swell energy barely gets a look-in, mostly sitting in the low double digits – we’re talking weak sauce, with maybe a few moments of moderate energy near the end. It’s just not happening. The only saving grace might be for the windsurfing or kite crew if the wind cranks, but for a surfer, it's a waiting game.
The water temp is sitting at 71°, which is about 1° warmer than the average for this time of year, so nothing crazy, just your typical warm summer water.
The one, maybe only, window where things get interesting is the morning of Sunday, the 30th of August. We finally see some proper WSW swell push in, with a size around 3 ft, and a bit more period behind it (7 seconds). The wind is offshore, straight from the ENE at a clean 9 mph. That's the kind of clean, glassy conditions we've been dying for. The combined energy jumps to 63, which is at least in the moderate range, giving the waves some push. If you can get out that Sunday morning, that's the call. The afternoon kicks up to 4 ft but the wind goes straight onshore, turning it into a choppy mess, so it's a short window.
Otherwise, there’s a glimmer on the morning of the 23rd of August, with a small 2 ft WNW swell and clean conditions, but it's nothing to write home about.
So, to sum it up: There are no real standouts for two weeks. It’s mostly a flat spell. Keep your eye on that Sunday morning, the 30th of August, for the best chance at a few clean, rideable waves at Les Conches. Everything else is just not worth the effort.

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.
