The Lowdown
Alright, folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. Let’s break it down.
We’re looking at a long stretch here with nothing worth getting excited about. The whole 16-day window is a write-off for decent surf. For the first week and a half, from Sunday the 23rd right through to Tuesday the 1st of September, the waves are tiny and the wind is all wrong. You’ll see a bit of a bump around Thursday the 27th of August, with some waist-to-chest high swell (5 ft) from the WSW, but it’s coming with onshore slop and a risk of thunderstorms. The wave energy is moderate at best (287). It’s just not clean.
Then things get proper messy. On Friday the 28th of August, the swell absolutely jacks up to a solid 10 ft from the WSW, with a very strong energy reading (1690). But don’t be fooled – it’s blowing a gale from the same direction at 28 mph, straight onshore. That’s not surf, that’s a washing machine. Unless you’re kiting, give it a wide berth. This kind of onshore wind with that much power at a beach setup like Les Conches is really only interesting for the kite crew.
There is a tiny window on Sunday the 30th of August where the wind drops to a light breeze, but the swell is a pathetic 3 ft and weak (188). It’s not worth the paddle.
From there it’s all downhill. The rest of the first week of September is flat and messy. The water temp is sitting around a touch warmer than normal for this time of year at 72°, but that’s not gonna help the waves. Honestly, for the whole 16 days, there isn't a single standout session. We’re in a proper flat spell. It’s a blank run, and for this area, that’s not unusual. Don’t hold your breath, and don’t bother waxing up just yet. Forecasts can change, but right now, it’s a hard pass.

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.
