The Lowdown
Alright folks, Rusty here. Let me level with you about Les Dunes. Looking at the whole 16-day picture, it's pretty grim. The vast majority of the period is a write-off, with no real surf to speak of. The best we get is a single, very ordinary morning on the 14th, but even that's nothing to get excited about.
The opening stretch is a real bummer. From Saturday the 1st right through to the end of the day on Thursday the 13th, it's a solid two weeks of hardly any rideable swell. The swell heights are tiny, mostly between 1ft and 3ft, and the wind is almost always wrong. We get a lot of cross-shore and cross-onshore breeze from the WNW, which is chopping up what little bump there is. The combined energy is weak, barely cracking 100 for most of that time, sitting mostly in the teens, 20s, 30s, 40s, 50s, and 60s. It's a long, flat, frustrating stretch with nothing to recommend.
The only glimmer of something happens on the morning of Thursday, August 14th. The swell bumps up to 3ft from the west with a period of 9 seconds, and the combined energy gets up to 119 (moderate energy). The winds are light offshore from the NNE, which will clean the place right up. The water's about 69°, which is pretty normal for this time of year. But even then, the forecast just calls it "surfable waves but very ordinary conditions." It's not a standout, it's just the only thing on the menu. It’s a beginner-friendly size, but it's not going to be anything special.
After that, it's back to the doldrums. The 15th and 16th are back to tiny, messy waves with onshore winds.
So, the honest truth? There's no good surf on offer in this 16-day window. It's a blank run, and for this area, that's just how it goes sometimes. Keep your gear ready, forecasts can change, but for now, I wouldn't be waxing the board.
Rusty.

Information about the Les Dunes Surf forecast
The above surf forecast table for Les Dunes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Les Dunes can be found by selecting the local surf guide option on the grey menu. Our Les Dunes 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 Dunes) 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 Dunes 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.
