The Lowdown
Right then, let’s have a look at what’s on the cards for Les Conches. It’s a bit of a quiet start, to be honest. The water temp is sitting at 71°F, which is pretty normal for the time of year.
For the first few days, it’s pretty flat and messy. On Tuesday the 25th, you’re looking at tiny 0.7ft to 1ft dribble with onshore wind, so it’s just a no-go. That sort of weak energy (18) isn’t worth paddling for. Wednesday the 26th sees a bit more shape with some cross-off wind in the morning and even offshore in the afternoon, but the swell is still only 2ft. You’d be scratching for anything. Thursday and Friday are a write-off with onshore winds and the swell jumping up to a stormy 8ft on Friday afternoon, but it’s pure chop with combined energy hitting strong (1045). That’s more for the kites than paddleboards.
The weekend is rough. Saturday the 29th has a messy 5ft to 5ft onshore slop. Sunday the 30th morning is the first time we see a "maybe" with 5ft swell, but it’s cross-onshore and choppy (509 energy), so it’s marginal at best. Monday the 31st is similar with lumpy cross-onshore wind.
Right, here’s the first real standout. Mark your calendar for the morning of Tuesday the 1st of September. The wind goes glassy, dead calm, with a clean 3ft swell from the west. The period stretches to 11 seconds, so there’s a bit of groundswell pulse there. The combined energy is moderate (227). It’s a beginner break so that 3ft size is perfect for learning, and with glassy conditions, it’s going to be as pretty as it gets. That morning is the moment.
The rest of the first week of September is a mix of onshore wind and lumpy surf. Nothing special. The swell stays small, under 3ft, and the wind is mostly on or cross-onshore. By Friday the 4th, we’re down to tiny 2ft slop.
Now, looking further ahead, the 8th of September is a bit of a wild card. Tuesday morning shows a massive 12ft swell from the WSW with a 18-second period. That’s a huge, powerful groundswell (6608 energy), and the wind is glassy. However, for a beginner break like Les Conches, that’s way too big and dangerous – the file itself says it’s too big for this break. Only for experts, and even then, a beach break this size can be a close-out. The afternoon drops to 8ft, but the wind picks up onshore.
Wednesday the 9th of September morning is the other one to watch. A solid 5ft swell from the WSW with a 13-second period, combined with a light offshore wind from the NE. That’s clean, punchy, and the energy is moderate (681). That’s a really good morning for a confident beginner or intermediate. The afternoon fades with some cross-onshore wind.
So, in summary: the first week is mostly a bust. Tuesday the 1st of September morning is your glassy, clean shot at small waves. Then, if you’re a bit more experienced, Wednesday the 9th of September morning has a nice clean 5ft with offshore wind and a long period.
Stay patient.

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.
