Table - best surf conditions forecast for Les Dunes over the next 16 days.


Alright folks, Rusty here. Let’s be honest about the next 16 days… it’s going to be a tough stretch for a proper surf. The whole window is a write-off for quality waves, so I’m not going to sugarcoat it.

The first real chance of even getting wet doesn’t come until the tail end of the first week. Even then, the energy is just barely there. We’ve got a long, empty run ahead. The only spot on the radar is Les Dunes, but it’s rarely offering anything worth paddling out for.

Looking at the beginning, from Thursday the 9th of July right through to the start of the second week, it’s pretty much flat or blown out. The swell is tiny—mostly under 2 ft—with weak energy (48 or less). The wind is all over the place, mostly cross or onshore, making it choppy and messy. There’s no point even thinking about a board right now.

The one tiny glimmer comes on Friday the 18th of July. Early morning, we get a slight onshore breeze with a tiny 2 ft swell from the west. The energy is a measly 19, so it’s weak. But it’s a break from the constant chop. The wind goes cross-on again by the afternoon, so the window is short.

The real "best" of a bad lot might be the morning of Saturday the 19th of July. We’ll see a 3 ft swell from the west with moderate cross-shore wind. The energy is still weak (51), but it’s the most power we’ll see. The wind is choppy though, so it’s not exactly pristine.

After that, the last week of the forecast is a mess. Strong winds—fresh breeze at 19-22 mph—and messy, lumpy conditions. The swell is small and weak. The 0.7 ft swell on Thursday the 23rd of July has a long period of 10 seconds, but it’s so tiny it’s barely a ripple.

Honestly, for a beginner spot like Les Dunes, this is a long stretch of nothing. If you’re a kite surfer, the gales on the 21st and 22nd of July might be interesting, but for paddle surfing, you’re better off waiting for the next forecast update. The setup is just not cooperating.

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.
