The Lowdown
Alright, let's get real about Lacanau-Ocean. I’ve been staring at this forecast, and it’s a tough stretch for paddle surfers. The next couple of weeks are looking pretty flat and sloppy, so don't get your hopes up for any barnstorming sessions.
We start off with a real dud. From Tuesday the 14th right through to the morning of Friday the 24th, we’re looking at a solid block of poor surf. The swell is tiny, mostly around 1.0 ft to 3 ft, and the period is short, so those waves are just going to be weak and crumbly. There’s a bit of clean-ish wind in the mornings from the 19th, with the NE and N cross-offshores, but the swell is just too small to do anything with. Honestly, it’s a long wait for a wave.
Now, the first real sign of life comes on Friday the 24th. The swell finally bumps up to around 4 ft from the WNW. The problem is the wind is howling onshore from the W at 12 mph, which will just chop it up. It’s still a “poor surf” call, so don’t get too excited. The swell holds through the weekend at around 3 ft, but the wind is still a mess.
The standout window, and it’s not saying much, is the morning of Sunday the 26th of July. We’ve got a clean 4 ft WNW swell with glassy conditions. The wind is virtually nothing out of the WSW. The waves are still short period, so they’ll be a bit soft and fat, but for the first time in two weeks, the ocean will look inviting. It’s the only morning that’s surfable and clean, but it's still very ordinary. After that, the wind gets messy again and the swell fades, so that Sunday morning is your one shot.
Overall, it’s a painful outlook. The water temperature is about average for the time of year, so no need to worry about a cold shock. For now, the board stays in the van.

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.
