The Lowdown

Alright, this is Rusty. Let's have a look at what's on the cards for Les Dunes.

Alright, folks, let's be straight with each other. I've been staring at the charts for the next 16 days and, to be honest, it's a bit of a tough stretch for Les Dunes. We've got a massive gap of quiet, tiny conditions right through the start. The first proper week is pretty much a write-off for any kind of real surfing. The water is sitting at 70° which is a touch warmer than average for this time of year, but that's about the only thing going for us.

We kick off from Tuesday the 21st with a solid offshore wind from the NE, but the swell is laughable – just 0.7ft from the west. It’s a long-period 11-second swell, but there’s just no energy in it. The combined energy is a measly 10, so it's a complete dud. This flat spell drags on through the whole week. We get a moment of glassy conditions on Friday the 24th afternoon, but still with that same tiny 0.7ft west swell. The wait continues.

The first real sign of life doesn't show up until the end of the first week. On Saturday the 26th, we see a bump in size, but it’s a messy one. The swell jumps to 3.9ft from the WNW by the afternoon, with the combined energy hitting 109, but it's getting thumped by a fresh cross-shore wind. The poor quality just isn't worth it.

The only spot that might be worth a session is Monday the 27th morning. The swell drops back to 1.6ft from the WNW, but with a clean cross-offshore wind from the north and a light air. The combined energy is 89, so it's small but at least it's surfable and clean. The conditions are described as "ordinary," but it's the best we've got.

We see another small window on the morning of Friday the 31st. A 3.0ft WSW swell rolls in with a clean offshore breeze from the NE. The combined energy is 87, and it's "surfable but very ordinary." The period is a short 6 seconds, so it's a bit of a windswell, but it's the only chance for a clean wave that week.

The next week is more of the same. We get a glassy morning on the 1st of August with a 3.0ft west swell, but the combined energy is only 82. It's small and weak. The best looking morning in the second week is Monday the 3rd of August. We get a 3.3ft west swell with an 8-second period and a clean cross-offshore breeze. The combined energy is 116, so there's some moderate energy there. It's still "ordinary" but it's the pick of the second week.

So, to be honest, there's no one standout. The best on offer is that Monday the 27th morning for the cleanest conditions, or the 3rd of August morning for a bit more size. It's a quiet period, lads. The forecast can change, but right now, it's a patience game.

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.
