The Lowdown
Alright, Rusty here. Let’s talk Les Dunes.
We're in for a flat spell that stretches for a good while. The first real chance of any surfable swell doesn't arrive until about the second week of August, and even then, the conditions don't look great.
The first few days are tiny. Wednesday the 29th has a 0.4m WNW swell but with a glassy morning, the energy is weak at just 26. The wind is clean early, but it's just not worth suiting up for. Thursday and Friday are a mix of tiny cross-shore chop and no power. Most mornings have a clean look, but the swell is under 0.5m consistently.
Around Tuesday the 12th of August, a NW pulse brings 1.4m waves (moderate energy at 120). That's the biggest we see. However, the period is short at 5 to 7 seconds, so the wave shape will be crumbly and weak. The Wednesday morning after also holds some 0.7m with a slight offshore, but the period stays short. The wind turns choppy by afternoon.
The standout, if you can call it that, would be the morning of Tuesday the 12th of August. You’ve got a 1.4m NW swell with clean offshore wind from the east. It's the only time in the entire outlook where there's both size and clean conditions. But the poor wave quality and short period are a letdown. This is not for beginners—at that height, it's a step up—but the quality will disappoint.
After that, it drops right back to nothing.
It’s a tough stretch. Not much to get excited about, but that’s how it goes sometimes. Forecasts can always change.
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.
