Alright, Rusty here again, folks. This 16-day stretch for Les Dunes is a real bust for the most part. Mostly flat, small, and messy, so don’t expect much. It’s a long, quiet run until the very end.

The first little bit of surf worth mentioning comes in on Sunday morning, July 5th. You’ve got a little 2 ft swell out of the west, period around 10 seconds, combined energy a weak 70. The wind is light and offshore from the NE, so it’ll be clean, but it’s just small and ordinary. This is a beginner wave, fairly consistent, and the optimum direction from WSW doesn’t match the swell. Crowds can show up sometimes. Water temp is about normal for this time of year.

From Sunday afternoon on July 5th right through to Saturday the 11th, it’s a whole lot of nothing. Swells drop to 1 ft, 1 ft, and energy levels stay between 21 and 89. Winds are cross, cross-on, and onshore, with only a few cleaner moments. On July 12th, Sunday afternoon turns glassy, but with only 2 ft of swell and energy at 46, it’s still pretty flat.

Then from July 13th to July 18th, it’s just tiny—swells down to 0.7 ft, energy as low as 6 or 37. The wind varies, but nothing turns this into a rideable wave. Total doldrums.

Now come July 19th, Sunday morning, we see a little life—2 ft of swell from the WNW, 11-second period, energy hits 181. Light cross-onshore wind, but still the report calls it poor. That afternoon, though, things go big—8 ft swell from the WSW, 9-second period, and energy explodes to 826. But the wind is fresh and cross at 30 km/h, so it’s lumpy and messy. That size is way too much for this break, only for experts. Not recommended.

Finally, July 20th, Monday morning, 5 ft from the west with 8-second period, energy 278, but the note says the swell is too big for this break. Winds are cross-shore with a gentle breeze. Possibly better for kiteboarding than surfing.

Best bet of the whole period? That Sunday morning on July 5th—tiny but clean for a beginner. The bigger stuff on the 19th and 20th is too large or too sloppy. Huge gaps of flat, poor surf. Forecasts can change, but right now it’s a tough stretch.

Catch you on the next one.

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.
