The Lowdown
Alright folks, Rusty here. Let’s get into it for Lacanau Ocean.
Right off the bat, it’s a tough start. The first few days are looking pretty grim with strong onshore and cross-onshore winds messing up what little swell there is. The water is sitting at 73.2°, which is a touch warmer than we'd expect for this time of year – not a bad thing for a session in boardies, but the surf quality just isn’t there.
Tuesday the 28th morning is the first real glimmer of hope. We’ve got a clean, clean window with a light offshore breeze from the ENE. The swell is a modest 3.0ft from the WNW with a period of 10 seconds. The combined swell energy is only moderate at 175, but the wind is perfect, making it surfable but very ordinary. It’s not a standout, but it’s the best we’ve seen so far.
The outlook gets pretty bleak again after that. There’s a long stretch of poor conditions with small, weak swell and wind all over the shop. A couple of days with nothing worth paddling out for.
Then, on Saturday the 1st of August morning, we have a moment of glassy calm. The wind is virtually nothing, just a slight air, from the WSW. Swell is a tiny 2.6ft from the NW with a short period of 6 seconds, so the energy is weak at 96. It’s surfable, but very ordinary. You’ll be fighting for any sort of push.
The real standout, the one to circle on the calendar, is Sunday the 9th of August morning. The wind is light and cross-offshore from the NNE, which will keep the beach clean. We’re looking at a solid 3.9ft of swell from the WNW with a long 10-second period, giving a moderate combined swell energy of 271. The forecast says "expect good surf conditions," and that’s the only time we see that. This is the best on offer by a long shot. The wind is kind, the swell is there, and it’s a consistent spot. Crowds are possible here, but for a day like this, you’ll put up with it.
Before that, on Wednesday the 5th of August morning, there’s another clean window with a light cross-offshore breeze from the NNE and 3.0ft of swell from the WNW. The energy is moderate at 131. It’s a solid, surfable wave but very ordinary compared to the 9th.
So, the verdict: endure the cruddy first week, hold out for the 9th of August. That’s your session.

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.
