The Lowdown
Alright, folks. Rusty here. Let's have a look at what's on the menu.
Honestly, I'm looking at the charts and it's a bit of a quiet spell to start. The surf is small and the wind is messy for the first week or so. We've got a bit of a dry spell, with nothing really worth paddling out for until around Thursday, August 20th. That's a solid gap right there.
The one spot we've got on the radar is Les Conches. Water temps are sitting around 69°, which is about normal for this time of year, so no wetsuit drama there.
The closest thing to a standout comes in on Thursday, August 20th. Thursday morning we see a jump in swell to 5ft out of the WNW, with a nice long period of 13 seconds. The combined energy is up to 1381 (moderate), which is a big step up. The wind is light from the NNW, keeping it cross-shore and clean. This is the best window we've got. It's a west-northwest groundswell, and with that long period, it'll have some punch. It's a touch too big for beginners, but for the rest of you, that's the one to aim for. Friday the 21st morning also has some size at 5ft from the WNW, but with rain showers and a cross-on wind, it won't be as clean.
Beyond that, the swell drops back down and the wind turns onshore again. The following Sunday, August 23rd, has a clean morning with a 3ft swell from the west and a light northerly, but it's not the same quality as that Thursday. So if you're keen, pencil in the 20th.
Rusty.

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.
