The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the horizon for our local stretch.
The next 16 days are a bit of a waiting game, to be honest. Right now, there’s nothing worth paddling out for. The first couple of days are a total write-off with tiny, messy waves. We’re looking at a real dry spell from the start until around September 20th. After that, things start to get interesting, but it’s a long way off.
Les Conches is our only option here. It’s a beginner-friendly spot, exposed to the swell, and it’s fairly consistent. The water temperature is about average for this time of year, nothing wild.
The first real flicker of life comes on Sunday, September 20th. The afternoon shows a medium-period swell from the west-northwest around 3ft, but the real story is the combined energy hitting 801 (moderate energy). It’s a good sign, but the wind is light and cross, so it’s not perfect. The wave comment says “marginal” – it’s a tease, but it’s the first sign of something brewing.
The standout, the one to circle on your calendar, is Monday, September 21st. The morning is the pick of the entire forecast. We’ve got a clean, 3ft swell from the west with a 14-second period (that’s a proper groundswell, lads), and the wind is gentle offshore from the east-northeast. The combined energy reads 403 (moderate energy). The conditions are described as “good surf conditions.” For a break like Les Conches, which is a beach setup, that long period might make it a bit straight, but with offshore wind and clean lines, it’s going to be worth the paddle. The afternoon stays clean but the wind shifts cross-shore, so hit the morning session hard.
There’s nothing else that really lights up the page after that. The rest of the month is small, blown out, or onshore. A few mornings in the last week are clean but with tiny waves and strong winds, not really worth the effort.
So, that’s the story. A long flat spell, then a brief window of hope on the 21st. Keep your eyes on that one.
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.
