The Lowdown
Hey, Rusty here. Let’s break down Lacanau Ocean for the next couple weeks, and I gotta be straight with you – it’s a bit of a bummer.
The outlook kicks off with a real gap. The first chance at anything surfable is Sunday morning, August 9th, but it’s a tiny 1ft from the WNW at 10 seconds and there’s a risk of thunderstorms. The wind is glassy, so it’s clean, but the wave energy is weak (42). The water temp is 76°, which is way warmer than usual.
The whole first week is a real struggle. Monday the 10th has another glassy morning with 2ft from the NW, but it’s just barely surfable. The afternoons keep getting chopped up by cross-onshore breezes. Tuesday the 11th is glassy again at dawn, but it’s only 1ft with a short 8-second period and energy at a measly 37.
We finally get a little more push on Friday the 14th morning with 3ft from the WNW (163 energy), but that cross-onshore wind ruins it. Saturday the 15th is more of the same poor stuff.
The only moment that really gets your attention is the afternoon of Saturday, August 22nd. The swell bumps up to 4ft from the WNW, and the combined energy hits a moderate 249. But here’s the catch: it’s a gentle cross-onshore breeze, and the report still says poor surf conditions. With a period of only 8 seconds, it’s not a clean wave. For a wide beach like Lacanau, this is shaping up to be a better day for the kite surfers than for those of us on a paddleboard. The 24th of August shows a similar 4ft from the WNW (207 energy), but it’s cross-shore and choppy again.
So here’s the bottom line: There aren’t any real winners in this forecast. Your best bet is to chase the glassy, tiny mornings in the first week for some clean but weak waves. The bigger swell in the second week looks messy. It’s a rough run, but the forecast can always change.

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.
