The Lowdown
Alright, Rusty here, let’s talk about what’s coming up at Les Conches.
Honestly, the next couple of weeks are pretty quiet for good surf. There’s swell coming and going but the conditions are mostly rough. The water’s about 70°, which is normal for this time of year.
For the first week, you’ll see some swell but the wind is all wrong. Sunday the 30th, there’s a 4ft swell from the WSW but the wind is blowing onshore at 16-19 mph, so it’s just messy. Same story Monday – a bit more size at 5ft from the west, but again the wind wrecks it. Tuesday the 1st of September gives a brief chance: morning goes glassy with an offshore breeze from the ENE, and there’s a clean 3ft west swell. Energy is moderate (158) and it’s surfable, but still pretty ordinary. That’s the only real morning to get out in that first stretch. After that, the swell drops way down into the 1-2ft range through to Friday the 4th, with cross-onshore winds messing it up. Not worth paddling.
There’s a gap of poor or tiny surf until the morning of Saturday the 5th of September. That morning is a real standout. We get a clean 3ft west swell with a long 13-second period. The wind is a light cross-offshore from the north, so the waves will be clean. Energy is moderate (273). That’s the pick of the first week. Not big, but worth it.
After that, it flattens again until the morning of Saturday the 12th of September. That morning, the wind is offshore from the ENE, and we get a 4ft west swell (10-second period) with gentle offshore cleanup. Energy is moderate (291). A decent little window.
But the real standout of the full 16 days is Sunday the 13th of September. The afternoon looks excellent. A solid 6ft west swell, 10-second period, and the wind goes glassy – dead calm. Energy is strong at 648. That’s expert territory on size – too big for beginners – but for anyone with experience, that’s the session to mark. Expect glassy conditions and very good surf.
Monday the 14th of September morning still has some swell (6ft) with a cross-offshore breeze, but it’s not as clean. So, two real bright spots: Saturday morning the 5th, and that glassy Sunday arvo on the 13th. Get in the water then.
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.
