The Lowdown
Alright, folks, Rusty here. Let's break down the next couple of weeks. It's a slow burner for Les Dunes, with a big lull in the surf before anything really fires up.
The first week is pretty quiet. From Friday, July 24th through the end of the month, the swell is tiny, mostly 0.6ft to 1ft, and the wind is all over the place. You'll see a few glassy moments on Friday afternoon, but the surf is just not there. The combined energy is weak, and it's a write-off.
Then things start to look up on Monday, July 27th. The morning session shows a bit of life with a 3ft swell from the WNW, period around 9 seconds, and clean conditions with a light cross-off breeze. The combined energy is moderate at 116. It's surfable, but the conditions are described as very ordinary, so it's not a standout.
We then hit another dry spell for a few days. The swell drops back down, and the winds are messy. It's not until Saturday, August 1st that we get a real standout. The early morning is looking fantastic. The wind is glassy, absolutely calm, and the swell is a solid 4ft from the west with a period of 9 seconds. The combined energy jumps right up to 233, which is a moderate wave energy. The catch is that the forecast says this swell might be a bit too big for this beginner-friendly break, so it's one for the more experienced crew. For the beginners, it's probably a day to watch from the sand.
Sunday, August 2nd morning is another cracker. Again, a 4ft west swell, period up to 10 seconds, and a light cross-off breeze from the NNW. The combined energy is even stronger at 284. This is a quality groundswell and will be pumping, but again, the same caveat applies: it's predicted to be a bit too big for this spot.
After that, the swell fades away again. The second week from Monday, August 3rd onwards sees the swell drop back to 2ft to 3ft with poor conditions. The wind is mostly onshore or cross-shore, and the energy is low. Not much to get excited about.
So, looking at the whole 16-day window, the clear standout is the morning of Saturday, August 1st and Sunday, August 2nd. Those are the only sessions with solid swell, good energy, and clean wind. For the rest, you're better off waiting for the next swell. The water temp is about what you'd expect for this time of year, nothing unusual.
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.
