Table - best surf conditions forecast for Les Dunes over the next 16 days.
Alright folks, Rusty here. Gotta be straight with you – looking at the next 16 days, there’s not a lot to get excited about. We’ve got a long, quiet spell ahead at Les Dunes, then a bit of a ramp-up late in the game, but the conditions are going to fight us the whole way.
The week kicks off with barely a ripple. On Wednesday the 8th, we’re looking at tiny 1ft dribblers from the west with a weak 8-second period. The wind is a light cross-shore in the morning, but the energy is almost nothing (27). It’s a poor outlook for a paddle. Thursday the 9th morning offers the first glimmer of hope with some clean 2ft swell from the west, around 68 units of energy. The wind is a light offshore from the ESE, so the surface will be clean. It’s surfable, but very ordinary. The rest of the week and into the next is a write-off – onshore winds, choppy conditions, and tiny surf with ratings in the dirt. We’ve got a solid gap of poor conditions stretching right through until mid-July.
As we push into the second week, things get a bit more interesting, but the winds stay nasty. Friday the 17th is the one that catches the eye. Swell builds to a solid 7ft from the WSW with 8 seconds on the clock, pumping out 507 units of energy. That’s a serious amount of water moving, but here’s the catch – it’s blowing a fresh cross-onshore at 19 mph. That’s going to make for some lumpy, choppy lines. This one is for experienced surfers only; beginners should steer well clear. The swell drops a bit through the 18th but the wind stays messy. We see another bump on Tuesday the 21st and Wednesday the 22nd with moderate groundswell energy in the 4-5ft range, but the wind is strong and cross-onshore, just ruining any quality.
Honestly, the best bet for a clean wave might be that Thursday morning, the 9th of July, with the offshore breeze. It’s small, but it’s clean. Everything else is going to be a scrap with the wind, and some of those bigger days are going to be a washing machine. This setup at the beach looks more interesting for the kite crowd than us paddle surfers for most of the run.
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.
