The Lowdown
Alright, surfers, Rusty here. Let’s be straight with you – the next couple of weeks are looking flat and frustrating for the most part. I’ve scanned the charts for Lacanau Ocean, and honestly, it’s a tale of tiny waves and onshores messing things up. We’re going to have to be patient and pick our moments.
Right off the bat, Thursday afternoon is a write-off. There’s a bit of swell at 3ft, but a cross-on NNW breeze at 16 mph is gonna chop it all up. It’s not worth your time. The energy is weak (122), so don’t get any ideas. Water temp is sitting at 76°F, which is much warmer than usual for this time of year, so at least it’ll be nice to get in, even if the waves are junk.
Friday morning is the only real glimmer of hope for the near term. The swell drops to 2ft, but the wind goes glassy with a light NE breeze. That’s the good stuff. It’ll be small, sure, but it could be clean and lined up. It’s not going to be a barrel fest, but for a cheeky log or a fun fish, it might be your best bet. The energy is weak (50), so manage your expectations. Remember, the swell is coming from the NW at 6 seconds, which is pretty short and junky.
From Friday afternoon all the way through to the middle of next week, it’s a desert. The swell stays under 2ft, and the wind keeps flipping between cross-on and light onshores. Saturday and Sunday are poor. Monday morning is glassy again, but there’s next to nothing for waves. It’s a real frustrating stretch.
Through the early part of the following week, the 12th to the 16th, we see the energy numbers tick up a little, but the swell heights stay pathetic. There are a few onshore days, and the period is all over the place. None of it is surfable in any meaningful way. You’d be better off finding a different hobby for a few days.
Now, the second week gets a bit more interesting, but it’s still not great. Around the 17th and 18th, the energy picks up with some cross-on winds and 3ft waves. The Tuesday morning of the 18th is glassy again, with the swell holding at 3ft from the WNW with a 9-second period. That might produce a few clean, soft waves, but it’s still small. This is far out, so treat it as promising but uncertain.
Later in the week, the 20th and 21st, the swell finally pushes over 4ft, but the wind stays poor, mostly cross-on and choppy. This looks like messy, blown-out conditions. Given the strong onshores and the beach break setup, this could be more interesting for the kite crew than for us paddle surfers.
Honestly, this is a classic summer flat spell. For a beach break like Lacanau, this is a normal part of the season. It doesn’t look like it’ll stay this poor for long – these stretches never do – but you’ll have to be sharp to catch the clean windows. Keep an eye on that Friday morning and the glassy Tuesday the week after. That’s the best of what’s on offer, and it’s not saying much.
Rusty, signing off.

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.
