The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for Lacanau Ocean over the next couple of weeks. The Atlantic's starting to show some signs of life, but we've got a bit of a mixed bag to work through before we get to the real deal.

Right off the bat, there's nothing worth paddling out for on the Monday morning. We start with a tiny, clean 2ft of west swell with a long 16-second period, but the energy is weak (237) and it's just too small to get excited about. The water is a warm 73°, which is notably warmer than usual for this time of year, about 4° above average. The afternoon gets messy with a building swell but poor cross-onshore winds. Tuesday sees the swell build to 4-5ft, but strong onshore winds from the WSW just trash it. We get a brief chance on Wednesday morning with a 5ft northwest swell and clean cross-offshore winds, but the period is a short 9 seconds, making for a bumpy, disorganised ride. The afternoon turns to chop again. Thursday and Friday offer only small clean waves in the morning, around 2-3ft, with very ordinary conditions and minimal energy.

The first real standout doesn't arrive until Sunday, September 13th. A nice 4ft swell from the WNW with a solid 13-second period rolls in, bringing a solid 476 in combined energy. The wind is glassy in the morning, which is a huge positive. This is going to be clean, lined-up, and fun for intermediate surfers. Crowds are *sometimes* an issue here, but on a glassy Sunday morning, you can bet there'll be a few out.

After that, we get a run of clean mornings on Monday, September 14th (3ft at 12 seconds), Wednesday, September 16th (4ft at 11 seconds), and Thursday, September 17th (4ft with a nice offshore breeze - 6 mph from the ENE). All decent options for a session, but nothing that's going to blow you away. The afternoons remain plagued by moderate cross-shore winds.

Now for the absolute standout. If you can wait, Saturday, September 19th is the day. The morning brings a clean 5ft WNW groundswell with a very long 12-second period. The combined energy is a hefty 628 (moderate to strong). And the wind? Glassy. Absolutely glassy. This is premium, clean groundswell. Just a heads up: that long period (12 seconds) will be better on the banks and points, but for a beach break like Lacanau, it'll still be well-shaped, just with longer lulls between sets. It's an intermediate-friendly size, so get ready for some quality rides. Crowds will be inevitable on such a clean day. Sunday morning and Monday morning after that are still clean and surfable with 3ft, but the magic is on that Saturday.

We close out the window on Tuesday, September 22nd, with a clean morning: 5ft from the NW with 10-second period and good energy (479). A solid way to end the forecast.

To sum up: paddle for the small clean dawnies during the week if you're keen, but your two must-not-miss windows are the glassy Sunday the 13th and the absolutely pristine Saturday the 19th. That Saturday is the real gem.

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.
