The Lowdown
Alright, Rusty again, same spot, same story, but in feet and miles per hour for those who think that way.
Les Conches is in a quiet spell right now. Water temp is about average for the season. First chance to get wet is Friday the 11th with a puny 1ft west swell. The morning is dead calm, glassy as a mirror. Wave energy is a weak 66, so prepare for tiny, clean but barely surfable bumps.
The weekend stays small. Saturday morning is clean with a 2ft west swell, but it’s only got an 8-second period—short and weak. Sunday morning is glassy again with a 1ft west swell and a nicer 12-second period (93 energy), but still tiny. Both afternoons get wrecked by a moderate cross-onshore wind, turning it choppy and poor.
Mid-week, the swell tries to nudge up. Wednesday the 16th sees 3ft waves from the west, but the wind is cross or cross-onshore, and the period is short. Energy hits 143-190, but the quality is poor—lumpy and messy. Thursday the 17th morning is the best of the first week: a 3ft west swell, 11-second period, light offshore wind, and 144 energy. Clean, but small.
There’s a big dry spell until the last few days. Tuesday the 22nd afternoon is the first real standout: a 2ft west swell with a 16-second period—proper long-period groundswell. Energy is 207, so it has some punch for its size. The wind goes offshore from the NE, and the surface is clean. This long-period swell will work well at Les Conches, a fairly consistent beginner-friendly break. It’ll be small but clean and lined up.
The best of the bunch comes Thursday the 24th afternoon and Friday the 25th morning. Thursday afternoon has a 3ft west swell, 12-second period, and 294 energy, with fresh offshore wind from the ENE. Friday morning is similar: 3ft, 12 seconds, 232 energy, and steady offshore wind. The swell direction (W) matches up just right with the break’s optimal WSW. Expect clean, well-shaped waves. This spot can have a crowd sometimes, so on these better days, expect company.
Bottom line: the first week is mostly a dud for quality. The window from Tuesday the 22nd through Friday the 25th is your best bet. Not big, but with clean offshore wind and solid groundswell energy, it’ll be plenty fun.
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.
