The Lowdown
The opening days are flat and uninspiring. Monday morning the 14th has a small 0.6m swell rolling in from the west with a 10-second period, and the water’s already a touch warmer than usual for this time of year at 22°. It’s glassy, but it’s tiny and ordinary—nothing worth suiting up for. From there it fades fast. Tuesday and Wednesday are smaller still, with 0.4m to 0.8m scraps, and the wind turns cross-onshore or choppy, so you’re just looking at lumpy, poor surf. The energy’s weak too—values down around 27 to 122 on the combined scale—so it’s not doing anyone any favours.
Come Thursday the 17th and Friday the 18th, the swell bumps up a touch to around 0.8m to 1.0m, but the wind stays onshore or cross-onshore, and the surf quality is still poor. Friday afternoon sees a jump in energy to 597, but with a moderate cross-onshore breeze, it’s just messy. Saturday the 19th is more of the same, onshore and weak. Then Sunday the 20th morning finally gives you a clean window with a light cross-offshore breeze and a small 0.6m west swell—surfable, but very ordinary. Not exactly worth clearing your schedule.
The gap continues without any real recommendation until around the 21st. That Monday morning the 21st is the first bright spot. You’ve got 1.0m of west swell, a 14-second period, and a gentle offshore wind. The energy’s moderate at 416, and it’s clean. That’s about as good as it gets for this stretch, and honestly, it’s still on the small side. The afternoon fades to a cross-shore breeze and questionable tides.
After that, it’s a long, slow grind. Tuesday the 22nd and Wednesday the 23rd drop back to 0.4m to 0.5m with offshore winds—clean but tiny. Thursday the 24th is even smaller, 0.3m, with fresh offshore winds that are strong enough to make paddling a chore. Friday the 25th has a bit more push, 0.9m to 1.0m from the west-southwest with a long 14- to 15-second period, and it’s offshore and clean, but the wind is fresh to strong, making it hard to hold your ground. Energy’s up around 383 to 446, but the surf’s still marginal.
Into the second week it gets worse before it gets any better. Saturday the 26th is small and clean in the morning, but the afternoon turns onshore and mushy. Sunday the 27th is small again, 0.4m in the morning, then a questionable 1.1m in the afternoon with onshore wind.
The real kicker comes Monday the 28th. We’ve got 1.9m of swell from the west-southwest, and that’s the biggest of the whole period. But the wind is howling—45 km/h onshore in the afternoon, and the morning’s cross-shore with a chop. The energy’s strong, values hitting 712 to 725, but it’s a complete mess. That’s not surf for anyone but the most desperate, and honestly, with that wind and a beach setup, it looks more interesting for kite surfing than paddle surfing.
Tuesday the 29th drops back to 1.0m to 1.1m with fresh cross-onshore winds and light rain. Poor all around. So, bottom line: the best you’ll find is that Monday morning the 21st, and even that’s a small, clean day. The rest is a write-off. Keep the board in the car, but don’t hold your breath—this stretch doesn’t look like it’s going to reward anyone who waits.

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.
