The Lowdown
Righto, let’s have a look at what’s cookin’ for Lacanau. I’m Rusty, and I’ll tell it to you straight.
The next sixteen days are a real mixed bag. We’ve got a lot of onshore slop to wade through before we see any real reward. The first week is pretty grim, with mostly onshore winds and weak, short-period windswell. There’s a long gap with no good windows. Then, right at the end of the first week and into the second, we get a couple of standout windows that’ll make it worth hanging in there.
Don’t even bother this week. Tuesday the 25th of August is flat and blown out, with a tiny 1 ft from the WSW and a period of just 3 seconds – total mush. Wednesday the 26th morning shows some hope with an offshore Easterly breeze and a clean, 2 ft swell from the W, but the energy is weak (51). It’s surfable, but nothing to write home about. The rest of the week gets hammered by strong cross-onshore and onshore winds, with swell building to a messy 10 ft on Friday the 28th. That’s a heap of water (1660 energy), but with a strong breeze on it, it’s a washing machine. Not for paddling. Kite surfers might love it though.
The real glimpse of light comes on Tuesday the 1st of September. The morning session is a gem. Lacanau Ocean is looking at a clean 5 ft swell from the WNW, with a solid 10-second period and glassy conditions – dead flat wind. That’s a proper morning to be in the water. The water temp is about average for this time of year, so no surprises there. Just be aware, this spot can get crowded sometimes, so get in early.
Then we go back into the doldrums until another standout shows up on Sunday the 6th of September. The afternoon session is the pick: glassy conditions again, with a consistent 5 ft groundswell from the WNW, period of 11 seconds. Energy is strong at 604. That’s a really clean, punchy wave for intermediate surfers. It won’t be too big, and it’ll be well-shaped.
And for the real deep end, check Tuesday the 8th of September morning. A massive 10 ft swell from the W with a very long 15-second period is predicted. The energy is huge (3872). The finder says it might be too big for this break, and I’d agree. That’s expert territory only, and the long period will make it suck a lot of water off the banks, making it dumpy and dangerous. Not a beginner’s game.
So, to keep it simple: your best bet is the morning of Tuesday 1st September for a clean, fun session. The standout, however, is the glassy afternoon of Sunday 6th September – that’s the one to circle on the calendar for the best overall quality surf. It’s a bit further out, so keep an eye on the forecast, but it looks promising.
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.
Lacanau Ocean is 38 km (24 miles) from Arcachon. If you plan a holiday in Gironde, look for hotels and other accommodation in Arcachon. Arcachon has rooms for a wide range of budgets as well as car hire and transport links.
