Alright, listen up. This is a rough one for Les Dunes. The whole 16-day window is a real bummer, with no decent surf to speak of. The swell is ankle-high and the conditions are messy for the most part. There’s a massive gap from the start all the way to the middle of the month where you’re just not going to get a wave worth paddling for. The only hint of something doesn’t show up until the second week, and even then, it’s got a big problem.
You’ll see a few mornings with glassy or clean conditions, like Tuesday the 7th, Wednesday the 8th, and a few others, but the swell is barely a ripple – 1ft or 1ft. It’s not going to break. The combined energy is weak, hanging around 20 to 30 (26). Not worth the rubber.
The first real sign of any size comes on Friday the 18th and Saturday the 19th, with the swell building to 4ft and the combined energy climbing into the moderate range (187). But the wind is all cross or cross-onshore, making it choppy and messy. It’s a no-go.
Now, the standout moment, and I mean the only one, is Monday the 20th and Tuesday the 21st. The swell pushes up to 4ft and 5ft from the west-northwest, with the combined energy jumping to 186 and 461 – that’s a real push of water. The wind is forecast to be light or offshore, which would make it clean. That’s the good news. The bad news? The guidance (Finder JSON) says for both days: “the swell is predicted to be too big for this break.” This is a beginner break, and 4ft is more than 5ft, so it’s too big for beginners. While it’s not over 8ft, the file is clear that it’s too much for this spot. So, for the experts, it might be the only window, but it’s a very uncertain one with high risk of it being a washing machine. Everything else is a write-off.
For the kite surfers, with the moderate to strong winds and poor surf quality on the days with any swell, especially from the 18th to the 21st, the setup looks far more interesting for kite surfing than paddle surfing.
Look, the water is a touch warmer than normal at 68°, so that’s one small comfort. But honestly, for a paddle surfer, this is a blank run. It’s not unusual for the area, but it’s a long wait for nothing.

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.
