The Lowdown

Alright, Rusty here. Let's have a look at what's on the cards for our stretch of coast over the next couple of weeks.

To be straight with you, it's a pretty grim run. We're looking at a solid two weeks of mostly poor conditions before anything even gets close to being worth a paddle. The first real sniff of anything half-decent doesn't come until Wednesday, 2nd September, and even then it's barely a whisper.

From now until the start of September, the wind is howling onshore, mostly from the west and southwest, smashing up any swell that tries to show. We see a bit of a pulse of energy on Saturday, the 29th, with the combined swell energy hitting 508 (moderate to strong energy) and waves around 7ft, but that west-southwest wind is blowing 25 mph straight on. It's going to be a complete washing machine – more of a kite-surfing session than a paddle-out.

The situation stays ugly right through to Wednesday morning, the 2nd. On that morning, we finally get a brief window. The wind swings to the north at 9 mph, giving us a cross-offshore breeze and clean conditions. The swell, however, is tiny at 2ft from the west with a short period of 8 seconds and the combined energy is a weak 87. The report says "surfable waves but very ordinary conditions." That's about as optimistic as it gets. The break at Les Conches is exposed to the west-southwest, so it can grab a little bit, but for a beginner-friendly spot, this is about as small as it gets. The water temp is a pleasant 70°, about average for this time of year.

Looking further out, there's a glimmer on Saturday morning, 5th September. The wind is a light northerly at 3 mph, giving us clean surf with a cross-offshore breeze. The swell is still small at 3ft from the west, but it's got a long period of 12 seconds and the combined energy is a moderate 227. That long period could give the waves a bit of shape, but at a beach setup like this, it might also make things a bit straight. It's not a standout by any stretch, just the least bad option.

The rest of the second week is more of the same: small, weak, and largely blown out. We get a few mornings with offshore winds from the east-northeast on the 8th and 9th, but the swell is a pathetic 0.7ft to 1ft. You'd be scratching for a ripple.

Honestly, there's no "best" session here, it's flat. The closest thing to a recommendation is that clean Wednesday morning on the 2nd, only because the wind is right, but you'll need a longboard and low expectations. Don't hold your breath.

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.
