The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s in store for the next couple of weeks.
Gotta be straight with you – the start of the outlook is a bit of a bummer. For the first couple of weeks, from the 7th of August right through, the waves are tiny and the wind is just not playing ball. We’re talking barely a ripple, with cross-onshore winds messing up most of the sessions. The energy is weak, mostly sitting in the two-digit range (like 15 to 93), and the swell heights are below 3 feet. It’s pretty grim. There’s a brief moment on the morning of Sunday the 9th of August where it goes glassy, with a tiny 1 ft swell from the WNW, but it’s just not enough to get excited about. We’re looking at a long, dry spell here.
Then, things finally start to look up. The real standout is the morning of Friday the 21st of August. The swell has kicked up to 5 ft from the WNW, and the wind is a light offshore from the NNE, which is going to make things clean. The water temperature is a warm 76°, which is much warmer than normal for this time of year. The energy is solid, clocking in at 344 – that’s proper moderate wave energy. This is the best window of the whole forecast. Lacanau Ocean is consistent, and it’s an exposed beach break, so it’ll be handling that swell. For intermediate surfers, this is the session to aim for. The swell is a bit too big for total beginners though.
The afternoon of that same day fades a bit as the wind swings cross-onshore, and the following days drop back down to smaller, onshore slop. So, if you’ve been waiting, the 21st of August morning is your window. It’s a long way out, so keep an eye on the forecasts, but it’s the best promise we’ve got.
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.
