The Lowdown
G'day, I'm Rusty, and I'm gutted to tell you, there's absolutely nothing worth paddling out for at Les Dunes over the next 16 days. The whole forecast window is a write-off, with every single time slot flagged as poor surf conditions. It's a grim run, but sometimes that's just how it goes in this neck of the woods—a long blank stretch like this isn't unheard of. The good news is, it tends not to stay this flat for long, and forecasts can always change, so don't toss the board in the shed just yet.
Looking at the little bumps that do show up, they're all tiny. From Friday 31 July right through to Saturday 15 August, the swell height barely ever touches 3 ft, and the combined wave energy is mostly weak, with the highest reading just hitting 132 (moderate) on Saturday 8 August. The wind is a mess too—mostly cross or cross-onshore, gusty, and often choppy. There's a brief moment on Sunday 9 August where the swell jumps to 6 ft (WSW) with a 9-second period and moderate wave energy (606), but it's cross-on and the wind is onshore, ruining any chance of a clean wave. That same day, the swell is actually predicted to be too big for Les Dunes, which is a beginner spot, so it's a no-go for most.
The only halfway decent conditions pop up on Sunday 2 August morning, with a gentle offshore wind (ENE) and clean surf on a 1 ft, 8-second W swell. But the energy is a measly 31, so you'd be scratching for scraps. The same goes for Friday 7 August morning—another offshore (NE) with clean lines, but again just 1.0 ft of W swell and 36 energy. It's not surf, it's a lake ripple.
Water temperature sits at 69°F on Friday 31 July, which is about normal for this time of year, but it won't help make the tiny waves any more fun.
So, no standouts, no highlights, just a whole lot of flat and messy. Hang tight, mate. The ocean will come back to life eventually.

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.
Les Dunes is 8 km (5 miles) from Les Sables-d'Olonne. If you plan a holiday in Vendee, look for hotels and other accommodation in Les Sables-d'Olonne. Les Sables-d'Olonne has rooms for a wide range of budgets as well as car hire and transport links.
