The Lowdown
Alright, let’s get into it. Conditions are looking pretty flat and ordinary for the most part, so we’re going to have to pick our moments carefully here. The first real chance to get wet doesn't come until Tuesday the 28th of July, and even then, it’s not going to blow your mind.
Tuesday the 28th morning at Les Dunes, we’ve got a small 2-foot swell from the WNW, with a period of 10 seconds. The wind is coming from the ESE, which makes it a cross-offshore breeze, so the waves will be clean. The combined energy is weak, just 74, so it’s not packing much punch. The water is sitting at 68°, which is pretty much average for the time of year given the anomaly is only -0.2°. It’s surfable, but very ordinary. Beginners might find something to play on, but don’t expect anything too exciting.
After that, we hit a long flat spell. From Tuesday afternoon all the way through to the morning of Wednesday the 5th of August, the surf is poor. We’re talking about a solid week of nothing worth paddling out for. The swell is tiny, the wind is mostly onshore or cross-onshore, and the period is short. It’s a real bummer of a stretch.
The next glimmer of hope comes on the morning of Thursday the 6th of August. Again, it’s only 3 feet from the W, with a period of 7 seconds, and the wind is a cross-off from the NNE. The energy is still weak at 66. It’s surfable, but nothing special. Same story on the morning of Saturday the 8th of August: 3 feet from the WNW, period of 6 seconds, light cross-off wind from the ESE. Clean, but small.
Now, if you’ve got patience, the best of the run is shaping up for Tuesday the 11th of August. The morning session at Les Dunes is looking promising. We’ve got 3 feet from the WNW, with an 8-second period, and the wind is glassy – completely calm out of the WNW. That is a major positive. The combined energy is moderate, sitting at 147, so there’s a bit more push in the water. It’s going to be clean, glassy, and the waves should have a little more shape. This is the standout window. The only catch is that Les Dunes is a fairly consistent spot, but it can get crowded sometimes, so if you can get out there early, you’ll be in for a treat.
For the rest of the second week, it’s a mix of small, onshore slop and tiny, weak swell. Not worth getting too excited about. The afternoon of the 11th gets choppy, and the following days are just cross-on or onshore junk.
So, the call is: hold out for the morning of Tuesday the 11th of August. That’s your best bet by a long shot. The rest is a waiting game.

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.
