Alright, this is Rusty, and I'm lookin' at the charts for Les Dunes. We've got a pretty flat picture for the next couple of weeks, so let's not sugarcoat it.
Right now, the start is a bit of a tease. Sunday morning, July 5th has the only real chance to get wet. We're looking at a tiny, weak 2ft swell from the WNW, with a period of 10 seconds. The water's sitting at a comfortable 68°, which feels a touch warmer than normal for this time of year. The key here is the glassy, clean conditions from a light NE offshore breeze blowing at 6 mph. It's not gonna win any awards, but it'll be a fun, easy session for a beginner. At Les Dunes, a fairly consistent beginner wave, crowds are possible, so don't expect to have it to yourself.
Now, for the bad news. After that Sunday morning window, the weather turns against us. From Sunday afternoon right through to Tuesday, July 14th, we're looking at a massive stretch with zero decent options. The wind is all over the place—shifting from onshore to cross-shore—and the swell drops off to a paltry 1ft or 1ft. It's just ugly out there.
Tuesday morning, July 14th, shows a flicker of hope. We get a truly glassy morning with a light easterly breeze, and a 2ft swell from the west at a 10-second period. The combined energy is still weak (89), so the surf will be very ordinary. It's a tiny window, and it's better than nothing, but it's not a standout.
After that, the pattern continues. Thursday morning, July 16th, has a clean, gentle offshore from the NE at 9 mph, with a 2ft WNW swell. The energy is still low (93), but the conditions will be clean. It's surfable, but don't be fooled into thinking it's anything special.
The rest of the run through to Monday, July 20th, is more of the same: small, weak swells, and winds that either don't line up or blow too hard. The swell directions look fine, but the size just isn't there. There's nothing here for anyone other than a complete beginner on a longboard, and even then, you'll be scratching for waves.
So, truth is, this forecast period is a bit of a dud for Les Dunes. Hold tight, the forecasts can change, but as it stands, you're better off keeping your board in the car for another day. For the best chance, be on the water on Sunday morning, July 5th. Otherwise, it's a long wait.
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.
