The Lowdown

Right, let’s have a look at what’s coming up for Lacanau Ocean over the next couple of weeks.

The first few days are pretty grim, no two ways about it. Saturday the 29th and Sunday the 30th are write-offs with messy, onshore wind. Monday the 31st is still onshore and poor, but by Monday afternoon you’re starting to see a 10-second period WNW groundswell creep in around 6 feet – it’s still choppy, but there’s a bit of energy there (616). Patience, mate.

Now, Tuesday morning (1st September) is when things take a turn for the better. We’ve got a clean morning with a light NE cross-offshore breeze, a 4ft WNW swell at 10 seconds, and the combined energy is moderate at 295. That’s the kind of morning that gets you out of bed. The water is much warmer than normal at 76°, which is a nice bonus.

But the real standout – and I mean the one to circle on the calendar – is Saturday morning the 12th of September. The forecast is still a week and a half out, so keep an eye on it, but it looks like a beauty. Glassy conditions with a light SE breeze, a clean 5ft WNW groundswell with a 12-second period, and strong combined energy at 603. That’s going to be clean, lined-up, and full of push. If the wind holds, Lacanau Ocean will be a dream. Get in early; it’s consistent and crowds are sometimes around, but on a morning like that, you’ll be glad you did.

After Saturday the 12th, Sunday morning the 13th still has some nice clean waves with a cross-offshore breeze and 4ft at 10 seconds, but it’s a step down in power. The rest of the run after that fades away quickly.

So, short version: grit your teeth through the weekend, enjoy Tuesday morning, and lock in Saturday the 12th as your best shot.

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.
