Updates in hr min s Forecast update imminent
Let’s start with the only real highlight: Les Dunes. On Saturday morning, July 4th, it’s clean with a light offshore breeze from the NE at 10 km/h. Swell comes in at 0.9m from the WNW, with a period of 10 seconds – that’s a nice groundswell, good shape but will have longer waits between sets. The combined energy is moderate at 180. Water temp is 21°, which is much warmer than usual for this time of year, so you’ll be comfortable in a spring suit or even a shortie. The break is fairly consistent and works best with a WSW wind, but the offshore NE will have it looking pretty tidy. Crowds are possible here sometimes, but on a day like this, it might be worth a look.
Saturday afternoon, the wind shifts NW at 30 km/h and goes cross-shore, making things lumpy. The swell drops to 0.7m from the W. Not worth hanging around for.
Sunday morning, July 5th, is clean again with a light ENE offshore at 10 km/h, but swell is only 0.7m from the WNW and the energy is weak at 85. Surfable but very ordinary.
From Sunday afternoon right through to Saturday, July 11th, it’s all poor surf conditions – tiny swells, mostly under 0.5m, with cross or onshore winds. The combined energy stays under 100 most of the time. Not much to report.
On Sunday morning, July 12th, there’s a bit of a pulse: 0.9m from the WNW, but a short period of 7 seconds and a moderate cross-onshore wind from the W at 20 km/h. Energy climbs to 115, but the wind messes it up. Not a goer.
Tuesday afternoon, July 14th, sees the biggest swell of the whole run: 1.1m from the WNW with a 10-second period and strong energy at 381. But the wind is cross-onshore from the WNW at 25 km/h, so it’s messy and lumpy. That’s a shame – could have been something with cleaner conditions.
After that, it drops back to tiny, poor surf through to Sunday, July 19th. The morning of Thursday, July 16th offers a brief moment with 0.5m from the W, light cross-offshore NNW wind, clean – but it’s really small. Saturday morning, July 18th bumps up to 0.8m from the W with moderate energy at 121, but again cross-shore wind from the NW spoils it.
Overall, the only session that stands out is Saturday morning, July 4th at Les Dunes. After that, it’s a long dry spell. If you’re itching for a paddle, that’s your window – don’t expect much else.

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.
