The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s headed our way.
First up, the water temp at Les Conches is sitting at 70°, which is a full 2° warmer than usual for this time of year. That’s a nice little bonus, makes the wait for a decent wave a bit more pleasant.
Now, I gotta be straight with you—this 16-day window is a tough one. There’s no real standout surf on offer. The first few days are a write-off. Thursday the 3rd and Friday the 4th are both showing poor surf conditions, with only tiny 2 ft to 2 ft swells. Friday morning does have glassy conditions, but there’s just no push.
Saturday the 5th is the first time we see something surfable, but it’s “very ordinary.” The swell bumps up to 2 ft in the morning with a 9-second period from the west, and the wind is a clean cross-offshore from the NE. The combined energy is moderate (147). By the afternoon, the swell hits 3 ft with a longer 13-second period, making it more of a groundswell feel, but the wind swings cross-shore. It’s marginal, but if you’re desperate, that afternoon might offer a few clean lines.
Sunday the 6th is a no-go with strong onshore winds, and the following week is a real grind. The swell never really gets going. There’s a brief moment on Wednesday morning the 9th with a 2 ft west swell and a light cross-offshore breeze from the NNE, but the energy is weak (80). Then again on Saturday the 12th, we get a 2 ft west swell with a clean offshore wind from the east, but it’s still just ordinary.
The only slight glimmer comes on Sunday the 13th. The morning shows a 2 ft west swell with a very long 14-second period. That’s proper groundswell energy, and with a light offshore wind from the east, it’ll be clean. The combined energy is moderate (177). But here’s the kicker—Les Conches is an exposed beach break, and a long-period swell like that tends to jack up and close out on a beach. It’s better suited to a point or reef. For a beginner spot, it’s probably a bit too tricky.
After that, it’s back to small, choppy, and mostly onshore or cross-onshore winds right through to the 18th. There’s a long gap from the 13th onward with nothing really worth paddling out for.
Bottom line: if you’re a beginner, this whole run is a miss. The best bet is Saturday morning the 5th for a very ordinary session, or Sunday morning the 13th if you’re a more experienced surfer who can handle a clean but punchy beach break. Don’t expect much.
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.
