The Lowdown
Alright, let’s break down what’s coming for Lacanau Ocean over the next couple of weeks. It’s a slow burner, a bit of a tease in the middle, and then some proper potential in the tail end.
The water is about 72°F, which feels a touch warmer than usual for this time of year – nothing dramatic, but you’ll feel it.
Friday morning is your first real look, but it’s tiny – a 2ft NW windswell with a short 8-second period and weak energy. The wind is dead glassy from the NNE at 3 mph, so it’ll be clean, just not much to work with. Afternoon, the wind picks up and turns choppy.
Saturday morning is similar, a small 3ft WNW swell, still a short period, but clean with a light cross-off breeze. Ordinary.
Sunday morning is the first real highlight. Swell bumps to 4ft from the WNW, and the period stretches to 13 seconds – proper groundswell. Energy is solid with a light NNE breeze making it clean. This is the best of the first week, though expect longer waits between sets. Afternoon gets messy.
Monday morning keeps it going with a clean 3ft swell from the WNW, a 10-second period, and a nice offshore breeze from the east at 6 mph. Clean, fun waves.
Then we hit a rough patch from Tuesday through Friday – onshore winds and poor quality. There’s a few days where you’re better off sitting it out.
Saturday, 19th September morning brings it back. Clean offshore conditions, a 4ft WNW groundswell with a 12-second period and strong energy. This is a real contender for the week.
Sunday, 20th September morning is also clean with a 4ft WNW swell and good energy.
But the real standout is Monday, 21st September morning. A 6ft swell from the WNW at 13 seconds, with a light offshore breeze from the ENE at 6 mph and very strong energy. This is the best of the whole forecast. It’s sizeable enough for intermediates and experts, but beginners will find it too big. The direction is spot on for Lacanau Ocean. The long period will favour the points and reefs.
After that, the swell drops through clean mornings, but nothing tops that Monday.
That Monday morning has some real sparkle to it. It’s a week out, so keep your fingers crossed, but it’s looking like the one to aim for.

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.
