The Lowdown

Right off the bat, I gotta be straight with you. The surf horizon for this stretch is looking pretty bleak. We've got a solid run of days where there’s just nothing doing—small, weak, and mostly messy. You’re gonna want to keep your board in the car for a while.

The only spot on the radar is Les Dunes (Normandy), a beginner-friendly beach break that’s fairly consistent, but even it can’t buy a wave worth paddling out for this week. The water temperature is sitting at 70°, which is about normal for this time of year, so that’s not the issue.

Let’s break it down. From Sunday the 16th all the way through Thursday the 20th, it’s a total write-off. Swell heights are mostly under 3 feet, the energy is weak–those combined energy values are mostly in the low double digits, like 58 or 78 (weak)–and the winds are chopping things up with cross and cross-on breezes. It’s a lot of closeouts and bump, not fun on a beach break.

Friday the 21st offers the very first glimmer. The morning is clean, with a light cross-off breeze and the swell bumping to 2ft from the WNW at 9 seconds. The energy is moderate (117), and the conditions are finally surfable, but it’s still very ordinary. The afternoon gets messy again, so you’d have to get out early for scraps.

Saturday the 22nd is poor again, and Sunday the 23rd has the right idea—clean, cross-off winds—but there’s just no swell to push it, only 1ft and 1ft, with energy dropping to 31 and then 17 (weak). It’s a lake out there.

Monday the 24th is more of a weather warning than a surf forecast. It’s choppy and stormy, but there’s a pulse of bigger energy arriving in the afternoon. The swell jumps to 7ft from the SW with a strong energy reading (617), but the wind is a cross-on mess, and it’s just too big and lumpy for a beginner spot. This one’s not breaking well; you’d be fighting it more than riding it.

Now, for the one standout in this whole 16-day window, it’s the morning of Tuesday, August 25th. The wind is offshore, light, and the surf is clean. There’s a 5ft swell from the NW, with moderate energy (146). The window is short, but the conditions align. However, there’s a catch: the comment says it’s predicted to be too big for this break. For a beginner spot like Les Dunes, 5ft is pushing it. It might be just over your head if you’re learning, but for anyone with a bit of experience, the clean offshore conditions could make for some fun, if a little shifty, sandbar peaks. This is your one shot. The afternoon blows out with a fresh cross-on.

After that, it’s a long, slow fade. From Wednesday the 26th right through Sunday the 31st, the swell just dies. We’re talking ankle-biters, 0.7ft to 3ft, with weak energy readings mostly in the low double digits. The winds are all over the place, but none of it matters because there’s nothing to push. The long gaps between any kind of rideable surf are going to feel like an eternity.

So, this is a real test of patience. There are no other options on the table; Les Dunes is the only break in the mix, and even it is mostly a no-go. It’s a classic case of the area going flat. It won’t stay this poor for long, but for now, maybe it’s time to check the forecast for another region or just get the kite out—that Monday afternoon swell with the strong cross-on wind might have more appeal for those with a foil than a fin.

Stay patient.

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.
