Alright, Rusty here, let’s break it down in feet and knots.

So, the picture is pretty grim for the next couple of weeks. There’s a tiny window early on, and then a bigger swell way late, but mostly you’re looking at a flat spell. The only joint we’re watching is Les Dunes. It’s a beginner beach, facing west-southwest. Water temps are sitting at 71°F, which is a good 5°F warmer than normal for this time of year – nice and warm.

The only real chance to get wet this week is Monday morning, July 13th. We’ve got a 4ft swell from the west, with a light north breeze making it cross-offshore. The combined energy is moderate at 120, so there’s some bump. The period is short though, about 6 seconds, so the waves will be a bit slow and soft. It might be a touch big for a total beginner, so be careful.

From Monday afternoon all the way through Sunday, July 26th, it’s flat and messy. Lots of onshore wind, lots of chop, and hardly any swell – we’re talking about ankle-snappers at best. There’s a couple of glassy moments, but with nothing to ride, it doesn’t matter. It’s a long, boring stretch.

Now, for the far-out stuff. Late in the month, around Monday, July 27th and Tuesday, July 28th, the swell really fires up. We’re talking 5ft to 7ft from the west, with combined energy hitting 382 and even 742 on Tuesday afternoon. That’s a lot of water moving. But the wind is a killer – it’s blowing straight onshore from the west and southwest at 12-18 knots. It’s going to be a washing machine out there at this beach break. That size is for experienced folks only, and with that wind, honestly, it looks better for a kite than a surfboard.

No real standouts. The Monday morning July 13th window is your only shot, and it’s nothing special. The late swell has power but no clean conditions. That’s the deal.

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.
