The Lowdown
G’day, Rusty here, and I’ve been staring at the charts for Lacanau Ocean. Let’s be straight with each other – this forecast is a tough one. The first week and a half is mostly a write-off, with only a tiny glimmer of hope way down the line. The water is sitting at a very warm 76°F, which is much warmer than normal for this time of year – feels like a bath out there.
We kick off on Saturday, August 1st. The morning has a tiny 2ft NW windswell, but it’s crossed up with a light north breeze. The wave energy is weak (51), and the conditions are just poor. The afternoon gets worse – a stronger NNW wind at 16 mph messes it up completely.
Sunday, August 2nd, sees the swell drop to 1ft from the west, with a bit more period (9 seconds). The morning is crossed, and the afternoon turns onshore. The energy is pitiful (36-49). This flat, gutless pattern basically holds all the way through to Saturday, August 8th. We’re talking about a solid week of barely any surf.
Then, on Sunday morning, August 9th, we finally see a pulse of energy. The swell jumps to 5ft from the west, with a moderate energy reading (263) – that’s the most juice we’ve seen. The wind is light and onshore from the WNW, so it’s not going to be clean, but it’s the most size we’ll have. This is the only standout in the whole 16 days. The swell is just on the edge of being too big for beginners, but for an intermediate, it’s the one to aim for. The period is a short 8 seconds, so it’ll be a bit soft and bumpy, but it’s the best on offer.
After that, it drops back into the doldrums. Monday, August 10th, is back to 3ft, and the following days are a mix of tiny 2ft to 3ft slop, with onshore winds and choppy conditions. The combined energy stays under 132 for the rest of the run.
To be honest, mate, for a break that’s usually consistent, this is a bleak run. The only real hope is that Sunday, August 9th, morning. The rest of the time, you’re better off checking the kite forecast, because the wind and waves are working against us for paddle surfing.
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.
