The Lowdown
Well, folks, it’s Rusty here, and I gotta be straight with you – this stretch of coast is looking pretty flat and frustrating for the next week or so. The only real surf option on the cards is Les Conches, but you’re gonna have to wait for it to come alive.
The pattern for the next several days is all about small, weak, and messy waves. From Thursday 27 August through to Monday 7 September, we’re looking at surf that’s mostly below waist-high, with poor quality and onshore or cross-onshore winds making a mess of things. The combined swell energy is weak, often under 100, with a few moderate days in the 150–400 range, but the wind and low period just ruin it. There’s a big gap of almost no surf worth paddling out for until things start to shift.
Now, the standout window comes in the second week – on Wednesday 9 September morning, things start to look up. A clean cross-offshore wind from the NE at 25 km/h sets up Les Conches (Charente-Maritime) with a 4 ft swell from the WSW, but the period is only 4 seconds, so it’s a bit junky. The afternoon though, that’s the real highlight: a 6 ft swell from the west, with a period of 7 seconds, and a clean cross-offshore breeze from the NNE at 9 mph. The combined energy jumps to 387 – that’s moderate, but it’s the best we’ll see. This is good for experienced surfers, but beginners might find it a bit too much. The swell direction is WSW, which matches the optimum for this spot.
Thursday 10 September morning keeps the clean vibes with a 3 ft west swell, 10-second period, and NE cross-offshore wind at 9 mph, energy at 219. Friday 11 September morning also offers clean conditions – 3 ft from the WSW, 11-second period, and a moderate offshore NE wind at 12 mph, with energy at 245. That longer period means better shape and more grunt, but it might make the sets a bit more spaced out.
Water temperature at Les Conches is 70°, which is about average for the time of year, so no surprises there.
So, if you’re patient, the best bet is Wednesday 9 September afternoon through Friday 11 September morning. The wind is clean, the swell is solid, and it’s the only real window of decent surf. Crowds are possible at Les Conches, so get in early.

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.
