The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Les Conches.
Honestly, it’s a pretty grim stretch ahead. We’ve got a long, long gap of flat or junk surf to start. The first sniff of anything remotely rideable doesn’t show up until Thursday morning, the 10th of September, and even then it’s barely a pulse. The pattern is mostly onshore junk and tiny dribble for days on end.
Thursday, 10th September is the first time you might paddle out, but don’t get your hopes up. You’re looking at a weak 2ft swell from the West, with a short, fat period of 8 seconds. The combined energy is pitiful (56), so it’s really just a grovel. The morning has a light breeze though, so it’ll be clean, just tiny. Not a standout by any stretch.
The next small window is Monday morning, 14th September. Again, small stuff—2ft from the West, period up a bit to 10 seconds. The energy is still weak (72), but it’s clean with a light cross-offshore breeze. You could get a few knee-high runners if you’re desperate, but the afternoon gets chopped up again by the onshore wind.
Things get a little more interesting toward the end of the run. Monday morning, 21st September shows a modest bump. The swell picks up to 2-3ft from the West, with a longer period of 11 seconds, giving it a bit more push and shape. The combined energy is moderate (157), and it’s clean with a light cross-offshore breeze. For the conditions we’ve seen, this is the best on offer. It’s still small, but that long period should give it some decent lines, especially on the sets. It’s a beginner-friendly size, and the crowds can be around sometimes, so keep your eyes peeled for a few other heads in the water.
Overall, there’s no real juice in this forecast. The only real standout is that Monday the 21st morning. For the rest, you’re mostly looking at small, clean windows that are worth a paddle if you’re itching, but nothing to plan a trip around.
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.

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.
