The Lowdown
Alright, let me tell ya what's happening. I'm lookin' at the charts for the next couple of weeks, and honestly, it's a tough stretch. We've got a run of poor surf conditions that goes on for a solid week and a half, from the 26th of July all the way through to the early part of August. There's just not a good window of swell and wind coming together for a proper session.
The only real flicker of hope comes at the very end of the forecast. On Monday the 10th of August, we might see a bit of a pulse. The swell is coming from the WNW at around 4 ft, with a moderate 7-second period. The combined energy is moderate at 168, and the wind is a clean, cross-off breeze from the north. That should clean things up nicely. Now, the swell direction is WNW, and the break is set up to handle a WSW swell best, so it's a bit off-angle, but with the clean conditions, it's the only thing on the radar worth getting a little excited about.
For the rest of it, you're looking at tiny, weak waves with poor, onshore winds. The water temp is about average for the time of year, nothing unusual there. This is just one of those quiet spells where the ocean takes a nap. Don't hold your breath, but keep an eye on the charts; things can change.

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.
