The Lowdown
Alright, Rusty here. Let's talk about what's cookin' at Lacanau Ocean.
Right off the bat, the next week and a half is looking pretty rough. We've got a real dry spell on our hands for the first nine days or so. There's almost no surf to speak of through the end of August and into the first days of September. The wind is mostly onshore and messy, and the wave heights are tiny or just blown out.
Now, this is a spot that's exposed to the west, and we're seeing some W and WNW swells trying to push in, but the conditions just aren't cooperating. The water temperature is sitting at a balmy 74°, and that's 5° warmer than normal, so it's a real anomaly – feels much warmer than you'd expect for this time of year.
The first glimmer of hope comes right at the start of September. On Tuesday morning, the 1st of September, we get a window of glassy conditions with zero wind and a clean 4 ft swell from the WNW with a period of 10 seconds. The combined swell energy comes in at a moderate 289, and the forecast actually says "expect good surf conditions." That’s a proper standout session if you can sneak out. It's not huge, but it'll be clean, and the crowd profile here can get busy, so that Tuesday morning window is your best bet for a calm session.
Another one to circle on the calendar is the morning of Wednesday the 2nd of September. We've got a nice 5 ft swell from the WNW with a longer period of 11 seconds, pushing the combined energy up to a solid 460. The wind is a light cross-offshore from the ENE, which should keep things clean. That’s going to offer up some decent shape, and the longer period means there'll be more energy in the waves.
The overnight into Thursday the 3rd also looks good, with a repeat of that glassy, calm morning and a 4 ft WNW swell (289 energy). But the Wednesday morning session looks like the true standout of the entire outlook.
Things start to taper off again by the end of the first week of September, with less consistency and the wind turning onshore again. Overall, you're looking at a long wait for it to turn on, but the 2nd of September is the one to plan for.
Rusty, signing off.

Information about the Lacanau Ocean Surf forecast
The above surf forecast table for Lacanau Ocean provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lacanau Ocean can be found by selecting the local surf guide option on the grey menu. Our Lacanau Ocean 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 (Lacanau Ocean) 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 Lacanau Ocean 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.
