The Lowdown
Alright, folks, Rusty here. Let’s be straight with you: this is a tough outlook for Les Dunes. There’s no real surf to get excited about for a good long while.
We’re looking at a real dry spell. The first chance you’d even want to paddle out is on Monday morning, July 27th. Even then, it’s a small 3ft swell from the west, with a 9-second period. The light offshore wind from the NNW will clean it up nicely, but the wave energy is low (168). It’s surfable, but only just. You’d be scratching for tiny, clean lines.
After that, it’s a wasteland of onshore and cross-shore winds for days. The wind just won't play ball. We grind through the end of July and into early August with nothing but poor-to-ugly conditions. The water temps are about average for the time of year, nothing to note there.
If you’re patient, there’s a slight spark again on Monday, August 3rd. The morning brings a little bump in the swell to 2ft from the west, with a light cross-offshore breeze from the NNE. The energy is still weak (79), but the wind will clean the surface. It’s still not a standout session, just the only one that doesn't look terrible.
The best of the bunch, if you can even call it that, shows up around Friday, August 7th. The afternoon sees a kick in energy - the swell hits 4ft from the WNW with a 8-second period, giving us a combined energy of 313, the highest in the outlook. But the wind is a fresh cross-shore from the WNW, which is going to make it lumpy with a cross-chop. It’s bigger, sure, but not clean. This one is more for the dedicated crew who just need to get wet, not for a nice day out.
Honestly, for a stretch of 16 days, there isn’t a single day that deserves the title of "standout." It's one of those periods where you leave the boards in the car and just watch the horizon. Forecasts can always change, but right now, this stretch looks pretty grim.
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.
