Alright, Rusty here. Let’s break down what’s coming for the next couple of weeks.
Water temp at Les Dunes is sitting around 68°, which is a touch warmer than normal for this time of year – nothing crazy, just a little extra warmth.
Through the whole 16-day window, it’s pretty grim. Swell is tiny, wind is messy, and you’re looking at a long stretch of poor surf. From Tuesday the 7th right through to Wednesday the 22nd of July, there’s not a single session worth paddling out for. That’s over two weeks of small, weak waves and lousy conditions.
The biggest bump comes late in the period, Wednesday afternoon the 22nd, with waves up to 5ft from the W, but the wind is cross-onshore at 12 mph and it’s going to be choppy. Combined wave energy hits 173 (moderate), but the period is only 6 seconds – short-period, junky stuff. That’s not a surfer’s wave, that’s more of a whitewash paddle at a beach break like Les Dunes.
For beginners, that 5ft might look tempting, but with the onshore wind and short period, it’s going to be messy and hard to catch. For anyone else, there’s nothing here that’s going to get the heart pumping.
This is a classic quiet spell for the area. It’s normal for Les Dunes to have flat runs like this, and forecasts can change, but right now there’s no standout day. The only spot is Les Dunes itself, an exposed beach break that works on a WSW swell, but with the wind all over the shop and the swell inconsistent, there’s no good bet.
Stay patient. Maybe save the board wax for another week.
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.
