Table - best surf conditions forecast for Les Dunes over the next 16 days.
Alright, Rusty here. Let me give you the lowdown in feet and miles.
Right now, Les Dunes is in a dead flat spell. From Saturday the 11th of July all the way through Wednesday the 22nd of July, there’s nothing worth paddling for – that’s 12 days with barely a ripple. Waves stay under 2ft most days, with short-period windswell and energy readings all under 100 – weak stuff. Wind is cross or cross-onshore, usually 10–20 mph, so the surface is chopped or messy.
Then on Thursday the 23rd of July, we see a bump – WNW swell hits around 4–5ft, period around 8 seconds, and the energy jumps to 229. But it’s crossed-up with wind from the WSW at 10 mph, keeping it ugly. Saturday the 25th of July brings a bigger pulse – 6ft swell in the morning, period 7 seconds, energy at 366. By afternoon, energy cranks to 492. That’s proper power, but the wind is cross-onshore at 15–20 mph, putting a chop on it. This is expert territory – too big and chewed up for most.
There’s one bright moment: Monday the 20th of July morning. Clean conditions, cross-offshore wind, and 3ft of WNW swell. That’s the only real window, but it’s short and the energy is low at 77. Still, if you have a longboard, that’s your chance.
No true standouts here. The best is that Monday morning at Les Dunes (France). Water temperature is average for the time of year. For kitesurfers, the stronger wind days around the 23rd–25th might be fun, but for paddle surfing, it’s a rough outlook. Keep an eye on it, but right now, take a break.
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.
