The Lowdown
Alright folks, Rusty here. Let’s not beat around the bush: the next 16 days are looking real flat for our stretch of coast. We’re in for a long stretch of poor surf.
We're starting off with days of tiny, weak surf. For the first week and a half, we're talking about ankle-biters in the 0.7ft to 3ft range. The combined swell energy is weak, usually under 100, with a lot of days in the 20s, 30s, and 40s. On the 2nd of August, it’s only 26. The swell is mostly from the west, which is okay, but there’s just no power. The period is short, mostly 8 seconds or less, so it's just wind chop.
On the 9th of August, there’s a little bump in energy to 102 and the swell hits 5ft, but the wind goes fresh and cross-shore, turning it into a lumpy mess. That’s typical for this stretch – any small pulse gets chopped up by the wind. We see a lot of cross and cross-on winds, picking up to 12, 15, even 22 mph at times.
The mornings do offer some clean windows with light offshores, like on the 6th and 7th of August. But the swell is just too small – 1ft on the 7th – so it’s not worth the effort. The period stretches out to 10 seconds on the 12th and 13th, but the swell is down to 1ft. It’s frustrating.
The only spot on the map is Les Dunes (*Nouvelle-Aquitaine*). It’s a beginner beach break that’s fairly consistent, but it won’t be breaking properly at all during this whole stretch. It’s mainly for a paddle if you’re desperate. The water temp is 69°, which is about average for this time of year.
So, there’s nothing on the horizon. This is a full-on blank run. Forecasts can change, but as it stands, we’re looking at a 16-day stretch of poor surf. Sometimes that’s just the way it goes.
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.
