The Lowdown
Alright, grab a coffee, let's have a look at what's on the table for the next couple of weeks.
First off, I gotta be straight with you—this is a rough patch. We're looking at a long, dry spell before anything remotely worthwhile shows up. From Tuesday the 28th of July right through until the 10th of August, it's pretty much a write-off. The swell is tiny, mostly under 2 feet, and the wind just won't play ball. You'll see a few mornings with a bit of a clean face, like on the 28th morning with that 2-foot WSW swell and a cross-off ESE breeze, but the energy is just pitiful (74). It's surfable, but honestly, you'd be scratching for something to ride. The rest of that week is a parade of choppy, cross-shore junk and onshore slop. Not a single standout in that whole stretch.
Now, let’s talk about Les Dunes. It's a beginner-friendly spot, fairly consistent, but it's exposed to that WNW swell. The water temp is sitting around 69°, which is bang on average for this time of year, so no surprises there.
The first real glimmer of hope comes on Tuesday the 11th of August. The morning session is looking like the pick of the entire forecast. We’ve got a clean 4-foot swell rolling in from the west, with a light offshore breeze from the NW. The combined energy is moderate at 303, and the period is a solid 9 seconds. It’s a proper groundswell, and the wind will be light cross-shore, keeping things tidy. It’s a bit too big for the absolute beginners, and you might find a few others out there, but it’s the best we’ve got.
The next morning, Wednesday the 12th of August, is actually a bit of a beast. The swell is forecast to be a solid 6 feet from the west, with a period of 9 seconds and a very strong energy reading of 575. But here’s the catch – the wind is onshore from the WSW, and the forecast notes this is too big for this break. This is for experienced surfers only, and even then, the conditions will be messy. This one is more of a spectacle than a session.
So, to wrap it up: the first two weeks are a total bust. The only real standout is the morning of August 11th at Les Dunes. It's not a world-class day, but it’s the only window of clean, rideable surf in the whole 16 days. The 12th offers raw power, but it’s for the brave and the skilled.

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.
