Table - best surf conditions forecast for Les Dunes over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Les Dunes is a tough one. The pickings are slim, and for the most part, we’re looking at a long stretch of unfriendly conditions. The whole forecast is a bit of a waiting game.
The first week and a half is pretty much a write-off. From Thursday the 9th through to the 19th of July, it’s a series of small, weak swells with poor surf conditions. The combined energy is low, mostly under 100, and the wind is never really on our side. The water temperature is around 68°, which is a touch warmer than normal for this time of year, but that’s small comfort when the waves are a mess.
The only real glimmer of hope, and the true standout, lands on Monday, 20th July. The morning session at Les Dunes is the best on offer. We’ve got a 4 ft swell from the west, with a clean, moderate offshore wind from the northeast. That’s the kind of wind that will hold the face open. The energy is moderate (152), and the wave height is solid for a beginner-friendly spot. Even though the swell is a bit short in period, the offshore breeze should make it worth a paddle. Just be aware, the afternoons get messy again with a strong cross-wind.
After that, we get a bit of a glassy morning on Tuesday the 21st with tiny 3 ft waves, but it’s really ordinary. Then the swell starts to build again late in the week, with 5 ft on the 22nd and 24th, but the wind is always cross or cross-onshore, making it choppy and tough. The 24th of July has a massive 702 combined energy, but with a fresh cross-wind, it’s a lumpy mess – more of a kite-surfing setup than a clean paddle.
So, mark your calendar for the morning of the 20th. That’s your best shot. Otherwise, it’s a lean patch, but forecasts can change, so don’t lose hope.
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.
