The Lowdown

Right, let’s have a look at the cards we’ve been dealt for this stretch. The first real bit of anything worth paddling out for is a fair way off, so don’t rush to wax up just yet. We’re looking at a long, quiet run with a solid gap of small, messy, or just plain wind-affected surf for the first week and a half.

The first real chance of a wave comes on Saturday, August 15, in the morning. That’s the standout of the whole window. Les Dunes picks up a 4ft swell from the west with an 8-second period. The combined energy there is moderate, sitting at 223. The wind is light from the NNW, making it a cross-off breeze, and the report says clean. This is a beginner break, so that 4ft is right on the upper edge of what’s fun for the less experienced, but the conditions are favourable. The swell direction is from the west, which is close to the optimum WSW. It’s a long way out, so treat it as promising, but it’s the best on offer.

The next morning, Sunday, August 16, is also worth a mention. A 4ft swell from the WNW with a 7-second period, combined energy 146, and a light offshore breeze from the NE. The wind is off, which is a big plus, and it’s clean. Again, the swell size is manageable for the beginners here, but the conditions are good. The wind switches in the afternoon, so get out early.

After that, the window closes. The rest is a mix of onshore winds, cross-shore chop, and tiny swell. The combined energy drops right back into the weak zone (mostly below 100), and the wave period is short and scrappy. There’s a long dry spell from the start of the week until that Saturday the 15th, so don’t hold your breath. The place is fairly consistent, but this run just has a lot of poor conditions, so it’s a waiting game. The setup is a beach break, and with the wind and chop on some days, it might look more interesting for a kite than a paddle.

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.
