The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The only break on the cards for this 16-day run is Les Conches, and I gotta be honest with you—it’s looking like a tough stretch for paddle surfing. We've got a long dry spell right off the bat. The first real flicker of something surfable doesn't pop up until Wednesday morning, the 26th of August, so you're looking at a couple of days of flat or junk before that.
Wednesday the 26th is where we start. The morning is cross-offshore with a tiny 0.8ft WSW swell, period short at 7 seconds, and the wave energy is weak (64). It’s surfable, but ordinary. The afternoon though... glassy conditions with the same 0.8ft swell and period. The combined energy is still low (67), so it's small, clean, but very marginal. Don't expect much.
Thursday the 27th is still mostly poor in the morning, but then Thursday afternoon things get interesting. We see the swell jump to 5ft from the WSW with an 11-second period and moderate energy (415). Wind is cross-offshore and light. The forecast says "expect good surf conditions." This is the standout of the first week for sure. The water temp is about 71°, with a small anomaly of 1°—so right around the norm for this time of year. The period is in that sweet spot for a beach break set-up, offering better shape but longer lulls between sets.
Now, after that brief window, we get hammered by onshore winds and messy conditions from Friday the 28th through to the start of September. There's plenty of swell, but it's all blown out—onshore and stormy. The 30th of August and 31st have some decent sized swell (4ft to 5ft), but with onshore winds up to 19 mph, it's a write-off for a clean wave.
We then hit a bit of a lull in size but still poor conditions through the 1st and 2nd of September. The next real pulse arrives Thursday the 3rd of September, but again, it's torched by strong onshore winds (22 mph). There’s a lot of energy (314) but it's just messy.
The 4th and 5th of September see some serious swell (7ft to 8ft) with very strong wave energy (over 1000), but with brutal onshore winds hitting 28 mph, this is strictly for kites if you're into that. The wave quality is poor, and at that size with those winds, it's a washing machine.
Now, here's the second real standout, and it's a classic long-range tease. Look at the 6th of September: Sunday morning. We get a tiny 3ft WSW swell, but check out that period—21 seconds! That's very long-period groundswell. The combined energy is massive (1072) for that small size because of the period. The wind is light and cross-shore, so it should be lined up. But remember, a period that long at a beach break like Les Conches might break too straight and close out. You'd want to find a bank or a point. The afternoon that day gets messy again with cross-on winds.
Then Monday the 7th of September morning? Glassy. A 3ft WSW swell with a 15-second period and exceptional energy (573). This is the best call of the whole outlook. Light winds, glassy conditions, and a long-period groundswell pushing in. The forecast says "expect very good surf conditions." This is a genuine standout—clean, with some push for the size. Worth marking on the calendar.
After that, Tuesday the 8th has some size (5ft) but the wind goes cross-onshore, dropping the quality.
Overall, Les Conches is a fairly consistent spot, so the poor run we see in the first week is just bad luck with wind. The two clear windows to aim for are Thursday afternoon the 27th of August for a solid, clean session, and Monday morning the 7th of September for what looks like the best wave of the whole 16 days—glassy and groundswell. The rest is either too small, too windy, or too big and blown out.
This is Rusty, signing off.

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.
