Alright folks, Rusty here. Let’s break down the next couple of weeks.

The forecast period starts with a long stretch of flat and poor conditions, so we need to be picky. There’s one clear standout, and then a few meager windows that are clean but weak.

Best session: Friday morning, July 3rd. Les Dunes gets a clean 3 ft swell from the WNW with a 10-second period. That’s a proper groundswell, not too big, and the wind is a light 6 mph from the NNE – cross-offshore, keeping the faces smooth. The combined energy is moderate at 231, enough to give you a decent push without being a battle. Water temp is 71°, which is much warmer than usual – a nice surprise. Crowds are possible here, but with conditions that good, it’s the time to go. That Friday morning is your window.

Saturday morning the 4th and Sunday morning the 5th are smaller – 3 ft and 2 ft (gentle offshore wind, NE 9 mph). Both are surfable but ordinary, with energy dropping to 138 and then 74. After that, from Monday the 6th through to Saturday the 11th of July, it’s a long, flat spell. Swell barely hits 2 ft, energy sinks to 41 or lower, and the wind is mostly cross or onshore. Not worth paddling out for.

There’s a slight uptick on Thursday morning the 16th of July – 2 ft swell from the WNW with a short 6-second period, but the wind is clean from the ESE at 12 mph (cross-offshore). Combined energy is only 31, so it’s weak, but it’s the only clean look in a very long stretch of dross. Friday the 17th is junk, onshore.

Honest summary: this is a lean period. The only true standout is Friday morning the 3rd. After that, you’re waiting over a week for a tiny, clean session on the 16th. Beginners will love that 3 ft on the 3rd, but otherwise it’s mostly too small or too messy. Some of those afternoons with a cross-breeze might be better for kiting than paddling.

Stay sharp, and make that Friday morning count.

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.
