The Lowdown
G'day, I'm Rusty. Let's have a look at what Lacanau-Ocean has got cooking for us over the next couple of weeks. It's a bit of a mixed bag, with some real clean gems tucked away in there, but plenty of average stuff to wade through too. The water's a touch warmer than normal for this time of year at 72°F.
We start off pretty quiet. Thursday the 10th and Friday the 11th are write-offs with poor, choppy conditions and tiny surf. Saturday the 12th morning offers a brief glimmer of hope with clean 3ft waves from the WNW, but it's pretty ordinary. That sets the tone for a few days.
The first real standout pops up on Sunday the 13th morning. The wind is light and cross-offshore from the NE, and the swell is a clean 4ft out of the WNW. The period is a solid 13 seconds, giving it some real grunt, with moderate combined wave energy (371). This is a good window for a session before the wind picks up.
Monday the 14th morning is also a good call. Offshore winds from the ENE and clean 3ft WNW swell with a 10-second period and moderate energy (225). It's not a massive day, but it'll be fun and clean.
The following week throws up a couple of bigger, more powerful options, but the wind is a problem. On Wednesday the 16th, we get 5ft waves, but it's choppy and cross-onshore – that's only for the experienced crew.
The real highlight of the whole forecast is Monday the 21st morning. This is the one to circle. Offshore winds from the east, clean conditions, and a cracking 4ft groundswell from the WNW with a very long 13-second period. The combined energy is a solid 506. That's proper, well-shaped wave energy, and it'll be clean as a whistle. It's an exposed beach break, so with that long period it might wall up a bit, but for the competent surfer, this is the session of the fortnight.
A few other mornings later in the week, like Tuesday the 22nd and Wednesday the 23rd, offer clean but smaller waves. Wednesday the 23rd morning has a tiny 2ft swell, but a massive 16-second period, giving it some surprising energy (242). It'll be a weird one.
Overall, there's a few good windows, but it's not wall-to-wall perfection. The 21st is the standout, but the mornings of the 13th, 14th, and 24th are worth a look if you can get out there. The afternoons are almost all blown out, so make sure you're an early bird.
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.
