The Lowdown
Alright folks, Rusty here. Let’s cut through the noise and talk about what’s really on offer for the next couple of weeks.
To be honest, the first stretch is dead. We’re looking at a solid run of tiny, weak, wind-blown surf that’s not worth getting wet for. From the 19th through the 21st, the swell is between 1 and 2 feet, with periods that are all over the shop, and the wind is onshore or cross-onshore. It’s just a mess. The wave energy is weak, sitting in the low double digits, and it’s not going to do anything for you.
The first faint hope arrives on the morning of Saturday the 22nd. The wind goes glassy at Lacanau Ocean (Gironde), and that’s always a beautiful thing. But the swell is still small, around 3 feet, with a weak 9-second period. It’s surfable, but you’ll be scratching for anything with a bit of push. The afternoon gets wind-affected again.
Sunday the 23rd is similar: clean and small, with the swell dropping to around 2 feet. It’s tiny, but an offshore breeze will make it look better than it is. Still, you’re looking at ankle-biters.
Then we go flat again from Monday the 24th through Wednesday the 26th. A real blank spell.
Now, the interesting part. The models are hinting at a more promising window arriving at the very start of next week. On Monday the 31st, we see a pulse of WNW swell around 4 feet, with a period that stretches out a bit, and crucially, an offshore wind in the morning. The energy jumps into the 200s, which is a significant step up from the doldrums. That’s the one to circle on the calendar. It’s a while away, so don’t book your flights yet, but that’s where the hope is.
There’s a bump in size on the 27th, but it comes with a choppy onshore wind and short periods. That’s a kite-surfing day, not a surfing day.
Water temps are about average for the time of year, nothing crazy there.
Bottom line: the early part of the outlook is a bust. Get your gear ready for Monday the 31st. That’s the highlight of the whole run, a real chance at some clean, head-high waves. Until then, it’s a waiting game.
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.
