The Lowdown
Alright, Rusty here again, looking at the same stretch in good ol’ feet and inches.
Pretty sleepy start to the outlook. Nothing worth paddling for until Tuesday the 1st of September at Les Conches. That morning, we’ve got a small west swell pushing about 3 feet with a 10-second period. Combined swell energy is 158, so there’s some power behind it, but the waves are small and conditions are just okay. Water temp is 70° – about a degree warmer than normal for the season.
If you had to pick a time to go, I’d say consider Monday the 7th of September early morning. There’s a WSW swell around 1 foot with a solid 14-second period, so it’ll be long lines, but tiny. Light east cross-offshore wind makes it clean, and the energy reading is low (91). Not for power-hungry surfers, but if you just want a glide, it’s your best bet.
Beyond that, there’s another pulse around Wednesday the 16th of September in the morning – a 5-foot WSW swell but with a short 6-second period, so short-period windswell that’ll feel weak and bumpy. Moderate offshore winds from east-northeast will keep the surface clean, but the wave quality is still ordinary.
Honestly, it’s a quiet stretch. If you’re just learning, the small clean days at the start are your friend. But for anyone chasing a proper wave, you might be waiting a while. Still, things can change quick around here, so don’t write it off just yet.
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.
