Updates in  hr  min  s Forecast update imminent

Alright, let’s get into it. Saturday afternoon, July 4th, we’re seeing a bit of energy from a west-northwest swell at Les Dunes, but honestly, it’s just not happening right now. The onshore breeze is ruining it, and the surf is messy. Keep the board in the truck for now.

The best bet in the next 16 days is shaping up to be Friday morning, July 17th. We’ve got a clean 6ft swell rolling in from the west with a north-northwest offshore breeze – that’s going to be clean, lined-up waves. The combined energy is strong at 892, and the period is 9 seconds, so there’s some nice push behind it. However, 6ft is on the bigger side for this spot, so this is going to be more for experienced surfers. Crowds could be an issue here as well, so get out early if you want a peak to yourself. That’s your standout window.

But before that, there’s a long dry spell. After the 4th, we’re looking at tiny, weak surf with onshore winds right through until July 16th. The swell stays below 2ft most days, and the winds are mostly cross-shore or onshore, so it’s all poor conditions. Not worth paddling out. There’s a brief clean window on the morning of July 12th with a light east wind and a 2ft wave, but it’s very ordinary – barely a longboard wave.

Then on Thursday afternoon, July 16th, the swell starts to build, but it’s still messy with a cross-onshore wind. Then Friday morning hits, and that’s your moment.

After that big Friday session, it drops off again. Sunday morning, July 19th, there’s a small 2ft swell with a light offshore breeze – clean but very small, more for the log or a fun little cruiser. The combined energy is only 99, so it’s weak. Not the same as the Friday stand-out.

Water temp on that first day is 68°, which is a touch warmer than usual for this time of year, so you’re good in a spring suit.

Overall, the one real standout is that Friday morning, July 17th. Don’t sleep on it. The rest of the run is either flat, blown out, or too big for the break.

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.
