The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the upcoming stretch for Les Dunes.
Well, I gotta be straight with you – it’s a tough run. For the next week or so, there’s just not much to get excited about. We’re looking at a long gap with pretty much nothing rideable. From Monday the 20th all the way through to Sunday the 26th, the swell is tiny, mostly 0.3ft to 0.7ft. Even with clean offshore winds early on, there’s no wave to work with. It’s one of those stretches where you’re better off checking the wind forecast for a kite session – the beach setup here with that small swell and a bit of cross-shore chop is way more interesting for that than for paddle surfing.
Then things start to stir late on Monday the 27th. The morning actually shows a little pulse of WNW swell, 3ft with a 9-second period, and the combined energy is moderate at 137. The wind is light and cross-offshore, so it’ll be clean. The catch is the swell direction is not quite optimum for Les Dunes – it’s exposed to WSW, but this is coming from the WNW. Still, it’s the first real chance in over a week, and it’s surfable, just very ordinary conditions. The water temp is a touch warmer than normal at 71°F.
The best chance in the whole window? That’s got to be Tuesday the 4th of August. The early morning is looking glassy – wind is basically nothing, just a slight air. The swell is 4ft from the WNW, with a period of 7 seconds. The combined energy is moderate at 167. The thing is, the wind and tide are favorable, but the swell is predicted to be a bit too big for this break. It’s a beginner spot, and 4ft can be a handful here. Still, for the experienced crew, that’s your window. After that, it gets messy again with cross-onshore wind and chop.
So, honestly, keep your expectations low. There’s a big gap with no surf, then a couple of so-so days, then one promising morning that’s a bit too big for the beginners. It’s a tough run for Les Dunes.

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.
