The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for Les Conches.
To be straight with you, the next two weeks are a mixed bag and not exactly firing on all cylinders. We’ve got a lot of time where the wind is just a pain in the backside, making things choppy and messy. There are a few windows of cleaner conditions, but they’re short and the swell is small. Don’t go booking time off work just yet.
We kick things off on Friday the 4th of September, but it’s a write-off – windy cross-on from the WNW at 16 mph with a tiny 2 ft W swell. Choppy and poor. You’d be better off waxing your board at home.
The first real glimmer of hope comes on Saturday morning, the 5th. The wind swings around to a clean offshore from the ENE at 9 mph. The swell is still only 2 ft from the W, but the combined energy is moderate (122). It’s small, but it’ll be clean and rideable on the longboard. The water temp is 70°, which is a touch warmer than normal for this time of year – nice for a long session.
After that, we hit a long, frustrating gap. The wind turns onshore or cross-onshore for days. Sunday the 6th has a tiny clean window in the morning with a 2 ft WSW swell, but it’s barely a ripple. From Monday the 7th right through to Saturday the 12th, it’s mostly onshore or cross-onshore wind with poor surf. There’s a pulse of bigger energy – 454 (very strong) on Monday afternoon – but it’s ruined by a strong onshore wind. No good.
Another small clean-up appears on Saturday morning the 12th, with a gentle offshore from the NE at 9 mph and a 2 ft W swell. Again, small but clean. It repeats on Sunday the 13th with a moderate offshore NE wind and a 2 ft W swell – decent for a small-wave cruiser session.
The middle of the second week is flat and boring. Monday the 14th has a glassy moment in the afternoon, but the swell is a pathetic 1.0 ft. Tuesday and Wednesday are similar – tiny.
Things get interesting again on Thursday the 17th of September. We get a cross-offshore wind from the NNE at 16 mph, a clean 3 ft W swell, and energy ramps up to 302 (strong). That’s the pick of the whole forecast. The direction is favorable, the wind is clean, and it’s a proper fun-size wave. That will hold into Friday the 18th and Saturday the 19th, with similar cross-offshore winds and 3 ft to 3 ft swell. It’s not huge, but it’s the most consistent, clean surf in the whole outlook. That Saturday morning, the 19th, with 16 mph NE wind and a 3 ft W swell is your best bet for a hassle-free session.
For the standout, I’d point you to Thursday the 17th of September. That’s the biggest, cleanest combination we get. It’s only for the experienced though – while the wave height is small, the energy is strong. Beginners will be fine on the smaller, cleaner mornings on the 5th and 12th. Expect a few other locals in the water, but nothing crazy.
Rusty out.

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.
