Table - best surf conditions forecast for Les Dunes over the next 16 days.
Alright, let’s see what’s cookin’ at Les Dunes for the next sixteen days.
Honestly, buddy, it’s a rough stretch for gettin’ a wave. We’ve got a long, flat spell ahead with not much to sink your fins into. The water is sittin’ at 71°, which is a solid 4° warmer than usual for this time of year – that’s really notable, almost like summer just won’t quit.
For the first week and a half, from Sunday, July 12 right through to the morning of Monday, July 27, it’s gonna be a total washout. The swell is tiny, mostly around 1 foot to 2 feet, with periods all over the place but generally weak. The combined energy is in the low double digits, mostly under 100, so there’s just no power in the water. Winds are a mix of cross, cross-on, and onshore, with only a few glassy or light wind moments, but even then the swell is too small to bother with. There’s a couple days with a little bump – like Wednesday afternoon, July 15 with a 4-foot windswell, but it’s a 4-second period, cross-shore wind, and the energy is only 76 – that’s messy and weak, not worth paddlin’ out for.
Then, finally, on the morning of Monday, July 27, we get a real pulse. The swell jumps to 6 feet from the west, with a 7-second period, and the combined energy hits 346 (moderate energy). The wind is a gentle cross-shore from the northwest, so it’ll be fairly clean. But here’s the catch – the guidance says the swell is predicted to be too big for this break. Les Dunes is a beginner spot, and 6 feet is pushing it for a learner. The wave comment flags it as wind and tide favorable, but the size is a problem. It’s a one-shot deal too, because the afternoon goes back to poor with a stronger cross-shore wind.
So, if you’re an experienced surfer and you’re desperate, that Monday morning, July 27 is your only window. But for the average surfer, let alone a beginner, it’s not a standout. The break is fairly consistent, but the quality just isn’t there for most of the forecast. The long gap of nearly two weeks with no real surf is pretty normal for an exposed beach like this when the swell direction is off. We’ll just have to wait and see if the forecasts 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.
