The Lowdown
Hey, Rusty here. Let’s call it like it is – this outlook for Les Dunes is a tough read. Over the full 16 days, there’s not a single standout session. We’ve got a long dry spell ahead, so temper those expectations.
The first bit of surf worth mentioning hits Monday, July 27th. Monday morning is the best of a bad lot. You’ve got a 3ft swell from the WNW with a 9-second period. The combined wave energy is weak at 146, and the wind is a light cross-offshore from the NNW at 6 mph, keeping the surface clean. It’s surfable, but very ordinary. By Monday afternoon, the wind turns onshore and picks up to 16 mph, making things choppy and poor. Tuesday the 28th drops to a tiny 2ft, and from there it’s flat. Wednesday through the weekend is barely a ripple – 1ft to 3ft of messy, weak swell with onshore or cross-shore breezes. Not worth paddling out.
There’s a bump early in the second week. Tuesday, August 4th brings a pulse of 4ft swell from the west with a 6-second period, and the wave energy jumps to 212 (moderate). Problem is, the wind is onshore from the southwest at 6 mph, and conditions are unknown. It’s still rated poor. Wednesday the 5th has similar 3ft swell from the west, energy at 123, but again onshore winds. By Sunday, August 9th, you get a bigger push – 5ft from the WSW in the morning, then 6ft from the west in the afternoon with wave energy hitting 401 (strong). But the wind is cross-onshore and the whole thing is rated poor. That’s going to be choppy and messy, more interesting for kite surfers than paddle surfers.
So here’s the bottom line: there are no good surf options in this 16-day window. Every single time slot is marked poor. The water temperature is about average for this time of year. Les Dunes is an exposed beach break that likes a WSW swell, but the wind and conditions just don’t line up. It doesn’t usually stay this poor for long around here, and forecasts can change, so don’t give up entirely. But for now, leave the board in the garage. That’s all I’ve got.

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.
