The Lowdown
Alright, grab a coffee and listen up. Rusty here, looking straight at the charts for our little patch. Let's be real from the start: the next 16 days are a tough watch. We're looking at a long stretch of small, messy conditions, and honestly, there's nothing here that's going to get the heart racing. We've got a solid 10 days from the start of the forecast up to the 3rd of August where the surf is just too small and poorly shaped to call it a real session. It's a bleak run, but that's the hand we've been dealt.
We finally see a tiny flicker of hope on Monday the 27th of July. The morning at Les Dunes is about as good as it gets in this window. We've got a tiny 3ft swell from the west-northwest, with a gentle 12 mph north-northeast breeze keeping it offshore. The combined energy is weak, sitting at just 140, but for this spot, that's the most we'll see. It's clean, but it's still just a knee-high dribble, and the water temp is a normal 68°F for this time of year. It's surfable, but don't expect any fireworks.
The other half-decent moment comes much later, on the morning of Monday the 3rd of August. A 2ft swell from the west with a clean 9 mph north-northeast offshore wind. The period is a short 8 seconds, so it'll be a bit crumbly, and the energy is weak at 64. It's a marginal option for a longboard or a foiler, but it's the only decent-looking morning in the whole second week.
Right now, the sea is flat and the wind is all over the place. It's a waiting game. The swell is too weak and the wind is too messy for most of the period. This setup looks more interesting for a kite surfer than a paddle surfer, to be honest.
Keep the board in the car and stay patient. The forecasts can change, but right now, there's not much to shout about.
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.
