The Lowdown
Right, let’s have a look at what’s on the cards for Les Conches over the next couple of weeks. Gotta be honest with you, it’s a bit of a quiet spell overall, and the first few days are looking pretty average. The water temp is sitting about 70°, which is pretty much what you’d expect for this time of year, nothing wild there.
The first real chance of a decent wave doesn’t roll in until Saturday the 5th of September. The morning is where it’s at. We’ve got a 3ft swell rolling in from the west, with a period of 14 seconds. That’s some nice long-period groundswell, which means proper shaped waves and good energy, but it might be a bit straight for a beach break – reefs and points would love this. The wind is light and coming from the north-northeast, giving us a cross-offshore breeze, so the face should be clean and lined up. Combined swell energy is a solid 412, so there’s some punch there. The crowd situation can be a factor here, so if it’s looking good, expect a few others with the same idea. The morning session on the 5th is the standout of this whole forecast. The afternoon on the same day gets chopped up by a cross-onshore wind, so don’t sleep in.
Before that, from now right through to Friday the 4th, it’s pretty forgettable. Small waves, choppy conditions, and mostly onshore or cross-onshore winds. You’ll see a few tiny 1ft to 2ft days, mostly blown out. Not worth the paddle.
After the 5th, we drift back into small mediocrity. Sunday the 6th brings a 2ft swell with offshore winds in the morning, but the energy is weak (84), and it’s just ordinary. Monday the 7th is tiny. Tuesday the 8th has a brief moment with a clean 3ft swell from the west, 12 seconds, and clean cross-offshore winds – surfable but nothing to write home about.
Then there’s another hopeful moment on Saturday the 13th of September. That’s a long way out, so take it with a pinch of salt, but the morning shows a 4ft west swell with a 14-second period and a glassy, light cross-offshore wind. The energy is right up there at 539. If the wind plays ball, this could be a cracker. The afternoon gets wrecked by onshore wind though. This one, along with the 5th, are your best bets.
Wednesday the 15th of September also has some potential showing on the guidance, with a 4ft swell and a very long 14-second period, but it’s too far out to get excited. Promising, but not certain.
Overall, the pick of the fortnight without a doubt is the morning of Saturday the 5th of September. Clean, long-period swell, decent size. Keep an eye on the 13th as a bonus if the forecast holds.

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.
