The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Lacanau Ocean over the next couple of weeks.
To be brutally honest, the next week and a half is lookin’ pretty flat and sad. We’ve got a run of tiny, weak swell that just ain’t gonna do much for a paddle surfer. The first real chance of anything worth wettin’ a wetsuit for doesn’t show up until Friday the 21st of August. Even then, it’s a real marginal call. The morning of the 21st sees a 3 ft swell from the NW, with a period of 11 seconds and a moderate energy reading (282). The wind is light from the NW, but it’s cross-onshore, so it’ll be a bit bumpy. It’s just not a standout.
The only window that might get your heart goin’ a little is Saturday the 29th of August. In the morning, we’ve got a 2 ft swell from the WNW, a period of 10 seconds, and a decent energy level (138). The real kicker is the wind: glassy, from the SSE at 0 mph. That’s a rare treat for this exposed beach. It’ll be clean, but it’s still small. For a confident surfer, the sets might offer a few fun little runners, but it’s not a day for beginners or anyone expecting a proper wave. The afternoon of the 29th gets a bigger 3 ft swell from the WNW with strong energy (201), but the wind swings to the W at 12 mph and onshore, which will mess it up.
Outside of that, most mornings through the end of August are plagued by onshore or cross-onshore winds from the NW or WNW, or just flat-out no swell. The water temp is about average for the time of year, so no weird surprises there. For a beach break like Lacanau Ocean, the long-period swell (like the 11 seconds on the 21st) might make things a bit fat and straight, but it's so small it won't really matter.
Honestly, if you’re desperate for a surf, the glassy morning on the 29th is your best bet. But if you’re lookin’ for a proper session, this forecast is a bummer. For kite surfing, those afternoons with a solid onshore wind and a bit of bump might be more interesting than for us paddle surfers.
Rusty.

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.
