The Lowdown
Alright, let’s talk Lacanau-Ocean for the next couple of weeks.
I’m not gonna sugarcoat it – this is about as quiet as I’ve seen it. From July 15 right through to July 30, every single check shows “poor surf conditions” with a big fat zero rating. The swell is tiny – mostly 0.6ft to 3ft – and it’s all short-period windswell, often coming from the wrong direction. Winds are mostly onshore, cross-shore, or cross-onshore, with a few glassy moments but nothing to ride.
The water is crazy warm – 77°F – and that’s 8°F above normal for this time of year. Feels like a warm bath, but you’ll be floating on a flat sea.
Lacanau-Ocean is usually a consistent spot, wide open to the west, so this kind of dry spell is unusual. I’m keeping the faith – forecasts can flip, and it’s rare to see a full 16 days of nothing here. But for now, there’s not a single wave worth chasing. Not for beginners, not for the pros – just flat, choppy, and empty.
Stick it out, something will turn.

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.
