The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the coming weeks.
Honestly, I gotta be straight with you – this is a tough stretch. The forecast for Les Dunes is pretty grim for the next 16 days. We’re looking at a long, dry spell with barely a ripple worth getting wet for. There's a big gap right from the start; the first few days are flat or junk, and the pattern just doesn't change. The only time it even gets a little interesting is around the 2nd of August, but even then, it's not what you'd call a proper session.
The one spot that gets a mention is Les Dunes. It's a beginner-friendly, fairly consistent beach break, exposed to the swell. The water temp is sitting around 69°, which is about normal for this time of year, so no surprises there.
The only morning that has a glimmer of hope is Sunday, August 2nd. We've got a small swell from the NW at 3ft, with a period of 6 seconds. The combined energy is weak (84). The wind is blowing offshore from the NNE at 12 mph, which will keep it clean. The waves are described as "surfable but very ordinary," and honestly, that's about as good as it gets. It's a low-score option, but it's the only one on the board. Expect crowds to be possible, as it's the only game in town.
The rest of the period is a write-off. The swell is tiny, the wind is either cross or onshore, and the energy is minimal. There's a brief moment on the 10th of August with a clean cross-offshore wind, but the swell is just too small to do anything with. Nothing else is worth paddling out for.
Don't hang your hopes on this one. It's a blank run. Forecasts can change though, so keep an eye on the sky.
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.
