The Lowdown
Alright, Rusty here, checking in from the coast. Let’s have a look at what’s coming our way for Lacanau Ocean. We’ve got a bit of a mixed bag over the next couple of weeks, with a few windows of clean conditions to keep an eye on.
Right now, it’s a bit of a write-off. Tuesday’s got a messy cross-on breeze with a 4ft to 5ft swell, but it’s chopped up and not worth paddling out for. The combined energy is moderate (357) but the wind is ruining it. We’ll have to wait a bit.
The first real chance to get wet comes on Wednesday morning, September 9th. The swell drops back a touch to 5ft from the WNW, but the wind swings around to a light cross-off from the NNE. That’s a game-changer. The period is a modest 9 seconds, but the energy is solid (381) and the conditions are clean. It’s not a huge standout, but it’s your best bet for the first few days. The water is about average for this time of year, so no nasty surprises.
Thursday morning, September 10th, is a tease. The swell drops to 3ft from the WNW, but the wind goes glassy. Absolutely glassy. It’s a perfect window for a longboard or a funboard. The combined energy is weak (182) but the conditions will be silky smooth. If you want a soulful session, that’s your moment.
After that, things get quiet for a stretch. The swell drops right off through the weekend and into the following week, with tiny waves and average winds. There’s a couple of mornings with glassy conditions and 2ft to 3ft swell, but it’s very ordinary. Not worth getting excited about.
Now, here’s the one to circle on the calendar. Monday morning, September 21st. We’ve got a 4ft swell from the WNW, but the wind is due to be glassy again. The period is a nice 11 seconds, which is a proper groundswell, and the combined energy is strong (431). This is the standout of the whole outlook. The waves will be lined up, clean, and playful. The only downside is that Lacanau is a beach break, so with that longer period, the sets might be a little straight, but with glassy conditions, it’ll still be a beauty. Expect some company though, as it’s a consistent spot.
Everything after that drops back into small, underwhelming surf. The forecast is a bit more shaky that far out, but for now, that Monday morning looks like the one to aim for.
Stay keen, stay patient.

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.
