The Lowdown
Alright folks, Rusty here. Let’s get straight into what’s on offer at Les Dunes. I’ll be honest, looking at the whole 16-day window, it’s a pretty lean stretch. There’s a long gap of flat, poor surf that kicks off the period, and we’re really waiting for the end of the first week before anything even remotely rideable shows up.
The first real chance to get wet is on Monday, July 27th in the morning. The swell is a tiny 3 ft from the west-northwest. The combined energy is moderate (119), and it’s a fairly consistent spot. The wind is a light cross-offshore from the north-northeast, which is a big positive for clean conditions. The water temp is about average for the time of year, so just a normal summer wetsuit. It’s surfable, but it’s very ordinary. This is about as good as it gets for the whole run, so if you’re a beginner, this is your window. It’s a small, clean wave. The swell direction is close to the optimum (WSW), so it should wrap in okay.
After that, it’s back to poor conditions. The afternoon of the 27th turns choppy and cross-onshore, and the rest of the week offers nothing but tiny, windy junk. There’s a brief moment on Friday, July 31st in the morning with a clean offshore wind from the northeast, but the swell is only 2 ft with a weak period (6 seconds) and low energy (49). It’s clean, but there’s barely a wave to ride.
The second week is a write-off. From August 1st through to August 7th, it’s consistently poor. The swell barely cracks 3 ft, and when it does on Monday, August 3rd (4 ft from the west), the wind is cross-onshore making it messy. The combined energy gets up to 147, but with a short 7-second period and onshore wind, it’s just a choppy mess. The forecast confidence is lower this far out, but the trend is clear: it’s not looking good. The only highlight is a clean offshore wind on Friday, August 7th in the morning (2 ft from the west), but that’s it.
So, bottom line: if you’re desperate, you’ve got a small, clean window on the morning of the 27th and maybe a slick, glassy morning on the 31st. After that, it’s a waiting game. Don’t hold your breath.
Stay wet,
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.
