The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for Les Dunes over the next couple of weeks.

Honestly, it’s a bit of a flat spell to kick things off. The first real chance of anything worth paddling out for doesn’t show up until Thursday the 6th of August, and even then, it’s pretty underwhelming. We’ve got a long stretch of poor surf conditions from Sunday the 2nd all the way through to Wednesday the 5th, with tiny waves, cross-shore winds, and a choppy mess. Not worth wetting a wetsuit for.

Thursday morning the 6th is the first flicker of hope. The swell is a weak 3 ft out of the WNW with a short period of 8 seconds, and the combined energy is only 90, so don’t expect much push. What makes it the standout here is the wind: a light NNW breeze coming cross-offshore, keeping the surface clean. It’s surfable, but very ordinary. You’ll be doing a lot of waiting for a knee-high lump.

The next decent window comes on Monday the 10th of August. Early morning sees a clean 2 ft from the NW with a gentle cross-offshore breeze. The period is still short at 7 seconds, so it’s weak, but the clean conditions make it the best bet of the first week. Not a classic, but it’s the pick of a poor bunch.

Into the second week, things get a little more interesting. Wednesday the 12th of August has some moderate offshore winds from the ENE, with a tiny 1 ft swell from the west. The period stretches to 10 seconds, giving it a bit more shape, and the offshore breeze will keep it glassy. The combined energy is only 47, so it’s small, but for a patient soul on a longboard, it’ll be clean.

The real highlight, if you can call it that, is Saturday the 15th of August. The afternoon session shows a 3 ft swell from the WNW with a 5-second period—so it’s weak and a bit short, but the wind is a solid offshore from the ENE at 12 mph. The combined energy is 69, and the conditions are described as surfable but very ordinary. For this spot, that’s about as good as it gets in this forecast window.

Sunday the 16th of August afternoon also deserves a mention: a light easterly breeze, 3 ft swell from the WNW with a longer 9-second period, and combined energy of 90. Clean, but still small.

Overall, there’s no big swell, no epic day. The best you’ll get is a clean, waist-high wave with an offshore breeze. Les Dunes is a beginner-friendly spot, exposed to the WSW, and it’s fairly consistent, but right now it’s struggling. The water temperature is sitting at 69°F, which is about average for this time of year, so no need for a thick suit.

Keep an eye on the wind shifts—the offshore days are your only window. It’s a waiting game.

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.
