The Lowdown
Alright, Rusty here, let's take a look at the 16-day forecast for Lacanau Ocean.
Right off the bat, I gotta be straight with you: for a spot that usually pumps, this stretch is looking pretty flat and ordinary. The water is a balmy 75°F with a 2°F anomaly, so it's much warmer than usual for this time of year – feels like a bath out there, but that's where the good news ends.
The first few days are a write-off. From Tuesday the 11th right through to the weekend, we’re looking at tiny, weak lumps with a combined swell energy barely scraping into triple figures (best being a 179 on Friday morning). Winds are mostly onshore or cross-onshore, keeping things choppy and messy. Honestly, for the first week, you'd be better off finding something else to do.
We finally see a faint pulse of life on Monday morning, August 17th. A glassy 4ft swell from the NW with a short period of 7 seconds. The combined energy jumps to 151, which is something, and the glassy conditions are a treat. But the surf quality is still labeled as very ordinary. It’s a possible dawn patrol for the keen, but don’t expect any gems.
The outlook then gets bleak again right through the 18th, 19th, and 20th – more tiny windswell and poor conditions.
Then, on Friday morning, August 21st, we get another whisper of hope. Glassy conditions again with a 4ft NW swell (period 6 seconds, energy 137). Again, it’s just surfable but ordinary. A session for the longboard or a foiler to scratch an itch.
The most interesting energy arrives on Saturday, August 22nd, with a big jump in swell height to 4-4ft from the WNW and a period of 10 seconds. The combined energy spikes hard to 364 and 389 – that's genuinely moderate wave energy. But here's the heartbreaker: it's accompanied by strong onshore winds at 16 mph. That’s going to turn it into a messy, blown-out wall. For a beach break like Lacanau, this combo is going to be more of a kite-surfing show than a clean wave for a paddle surfer.
The final week is more of the same: inconsistent, small, and mostly messy. There is a moment on Tuesday morning, August 25th, with an offshore breeze and a 2ft WNW swell – clean as a whistle but tiny. There is simply no standout window in this outlook.
So the bottom line: we’ve got a long, quiet run with no real standouts. For a spot that’s usually consistent, this is a poor spell. Don't hold your breath; check back, because forecasts can change, but right now, this is a blank week ahead.
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.
