The Lowdown
Right, mate, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, it’s a bit of a rough start. We’ve got some swell but the wind is just muckin’ it up for the first few days. The water is real warm, about 76°, which is a solid 6° warmer than usual for this time of year – that’s weirdly tropical for Lacanau.
The real standout in this whole outlook is Tuesday morning, the 1st of September. That’s the one to circle on your calendar. Lacanau Ocean is waking up with a light northerly breeze blowing cross-offshore, which is gonna keep the surface glassy and clean. We’re looking at a 4ft swell from the WNW, with a moderate energy level (301). The swell period is a decent 10 seconds, so there’ll be some shape and push. The waves are consistent, and the exposure is spot-on for that W wind swell. It’s not massive, but it’s clean and tidy – perfect for intermediate surfers. Just keep an eye out, because it can get busy there sometimes.
Before that, the weekend and Monday are a write-off. Saturday the 29th has 7ft of messy, cross-on swell from a strong SW wind, making for choppy, poor conditions. The energy is pretty high (651) but the wind is just shredding it. Sunday the 30th and Monday the 31st are a bit smaller but still onshore and grotty.
After that Tuesday morning high point, things drop off quick. Wednesday morning the 2nd has tiny 3ft waves, and the rest of the first week just fades into small, weak surf. There’s a glimmer on the morning of the 4th of September with glassy conditions and a 3ft swell, but it’s barely surfable.
The second week is a total bust. From the 5th of September onwards, the surf is tiny, mostly under 3ft, and the wind is either cross or cross-on, churning it up. The energy is low, and the waves are just not worth paddling out for. The gaps are long – days and days with nothing decent. The only real chance to get wet is that Tuesday morning, so don’t sleep on it.
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.
