The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Les Conches.
Truth be told, it’s a pretty lean stretch ahead. For the next 16 days, we’re looking at a lot of poor surf conditions, with only a couple of moments that could get you wet, but nothing you’d write home about. The first real chance to paddle out won't come until Sunday the 23rd of August, and even then, it's ordinary at best.
Sunday the 23rd of August shows a glimmer of hope with a small 2ft west swell and offshore breeze from the NE at 9 mph. The combined energy is weak (44), but the wind will be gentle offshore which will keep the surface clean. It’s not going to be a day for epic rides, but if you’re a beginner needing some practice on a tiny board, this is about as good as it gets for the entire 16-day window. The water temperature will be about average for this time of year, so no shock when you hit the water.
After that, it’s back to a long stretch of nothing with a few poor surf days through to Monday the 31st of August. On that Monday morning, we get a small 4ft west swell with a cross-offshore breeze from the east at 12 mph. The combined energy reaches 229 (moderate), and the wind keeps it clean. The swell period is only 7 seconds though, so it will be a bit short-period, and the waves will be a little weak. Marginal is the word – you could get a few, but don't expect magic.
Then on Tuesday the 1st of September we see a similar scenario. The afternoon brings a 5ft west swell, 9-second period, and light onshore wind from the WSW at 6 mph. The energy is strong (456), which means there’s some push behind it, but that onshore wind will likely make it a bit bumpy. Again, it’s marginal, okay for a frustrated surfer, but not a standout.
Honestly, the whole period is quiet. For the first week, there's almost nothing happening. The second week offers a couple of small, clean windows but nothing that will blow your mind. If you're desperate for a paddle, the Sunday the 23rd morning or the Monday the 31st morning are your best bets, but keep your expectations low.
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.
