Alright mates, Rusty here. Let's talk about what's happening on our doorstep.
Staring at the charts, it’s a pretty slow 16 days ahead. The swell is small and the wind gods aren’t playing nice. There are a couple of moments where you might get a wave, but there are no proper standouts to get excited about. The water temp is running about 71°F, which is much warmer than normal for this time of year – feels more like a tropical vacation.
We start off on Friday, July 3rd in the morning. That’s your best bet right now at Les Dunes. We’ve got a small 3ft swell coming from the WNW with a 10-second period. The wind is light out of the north, a nice cross-offshore, keeping things clean. The combined energy is moderate (191). It’s rideable, but nothing special. Don't bother with the afternoon as the wind turns onshore.
After that, things go quiet. From Sunday the 5th afternoon all the way through the middle of the month, it’s mostly tiny waves (1ft to 2ft) and rubbish winds. The energy numbers drop into the weak double digits (like 20 or 30). A proper flat spell.
Around Monday the 13th and Tuesday the 14th, the swell tries to lift a bit, with some 3ft to 4ft pulses from the west and a longer 12-second period. That longer period means more power between sets, but the wind is all over the place – strong cross-shore and cross-onshore – making it a choppy mess. The energy gets up to a moderate 358, but it’s wasted.
The best of a bad bunch might be Wednesday the 15th morning. The swell drops back to 3ft from the WNW, but the wind swings light from the north, giving us clean conditions again. Energy is moderate (118). It’s your last real shot at a few tidy small waves before the wind messes it up again.
Late in the run, we get some waist-high, messy swell pushed in by strong onshore winds. That’s kite-surfing territory, not for the paddle crew.
A lean few weeks, everyone. Keep your eyes peeled because it never stays flat for long around here.
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.
