The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer.

To be straight with you, the next 16 days are looking pretty grim. There’s a big gap of nothing worthwhile right from the start. The first real chance at something surfable doesn’t come until Monday, 27 July, and even then it’s nothing to get excited about. The only spot in the picture is Les Dunes.

That Monday morning, 27 July, we get a tiny 3ft swell from the WNW, with a weak energy reading (95). The wind is a gentle cross-offshore breeze, so the surface will be clean, but the waves themselves are just ordinary. Not worth paddling out for unless you’re desperate. The afternoon turns messy with a cross-shore wind and lumpy conditions.

The only other moment that might raise an eyebrow is Monday, 3 August, early morning. We’ve got a 3ft swell from the west, period around 8 seconds, and glassy conditions. The combined energy is moderate (104). It’s still just surfable, not good, but with the wind dead calm, it’s the cleanest you’ll see. That’s your best bet in this whole stretch, and it’s a low bar.

The rest of the period is filled with poor surf, strong onshore winds, and messy chop. A couple of afternoons show a bit more size – Saturday, 25 July, hits 5ft from the NW but with a strong cross-shore breeze and a 6-second period, it’s a total mess. More for the kite crew than anyone on a paddle board.

The water temperature is about average for this time of year, nothing unusual.

So, if you’re itching for a paddle, mark your calendar for the morning of Monday, 3 August. That’s the only window where the conditions line up to be clean. Everything else is a write-off.

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.

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.
