The Lowdown
Alright, Rusty here. Let's be straight with you, this is a grim outlook for Les Dunes.
We’re looking at a 16-day stretch that’s mostly a write-off. The water temperature is sitting at 69°F which is about average for the time of year, so that’s one thing that’s not a problem. The rest is a struggle. There’s a massive gap of nothing worthwhile from now until the start of August. The only flicker of life comes right at the very end of the forecast.
The first few days are a total bust. Swell is tiny, barely 0.7ft, and the combined energy (9) is weaker than a flat tire. The wind is offshore or cross-offshore, which would be a dream if there was any wave to surf, but there isn't. Wednesday the 22nd through to the end of July is just poor surf conditions with negligible wave height. Even when the wind is clean, there’s nothing to ride.
Thursday the 4th of August morning is a strange one. The swell jumps to 4ft from the west, and the combined energy shoots up to 364 (moderate energy). The wind is light and cross-offshore from the ESE, which means it will be clean. However, the forecast specifically says the swell is too big for this break. At 4ft, it’s still fine for most, but it’s a clear warning that this spot can’t handle it. For a beginner spot, that’s a no-go. For the rest of us, it’s a major caveat. The afternoon goes onshore and messy.
The only real standout, and I mean the *only* one, is Tuesday the 4th of August morning. It’s the best on offer by a long shot, but it’s a long way out, so treat it as promising but not guaranteed. Clean conditions, a bit of size, but the break itself may not cooperate. After that, we’re back to small, choppy, and unremarkable.
Honestly, this is a tough stretch. You’re better off looking for something else or waiting for the next system.
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.
