The Lowdown

Right, grab a coffee, settle in, because we’ve got a bit of a mixed bag coming up here at Lacanau Ocean. The start of the window is pretty average, but there’s a couple of real gems hiding in there if you pick your moments.

The water’s sitting about average for the time of year, nothing wild there.

We kick off on Wednesday morning, the 9th of September. The swell is a decent 5 ft from the WNW with a 9-second period, and the combined energy is solid (405). The wind is a cross-off from the NNE at 15 mph, which is going to clean things up nicely. It’s a bit of a standout for the first week, but don’t get too excited—the afternoon gets sloppy, and the next few days are a real letdown. Thursday and Friday see the swell drop, and the wind turns onshore or cross-on, making it messy. By Friday morning, the 11th, it’s a tiny 2 ft and glassy, but it’s just too small to get excited about.

Now, hang in there, because Sunday morning, the 13th of September is the first proper standout. We’ve got a 4 ft swell from the WNW, but the period jumps to 13 seconds—that’s proper groundswell energy (378). The wind is a light NE at 5 mph, making it glassy. Because it’s a long period swell, it’s going to peel nicely here, but it can make the beach break a bit straight. Still, this is the best of the first week.

The following week is a bit of a snooze. The swell stays small, mostly under 3 ft, and the wind is onshore or cross-on for most of it. There’s a little pulse on Saturday morning, the 19th, with a 4 ft from the NW, but it’s short period (8 seconds) and the energy is moderate (194). The wind is offshore from the ENE at 10 mph, so it’ll be clean, but it’s nothing special.

Now, the real treat is a week and a half away. Sunday morning, the 20th of September brings a 4 ft swell from the NW with a 10-second period, and the combined energy is solid (256). The wind is a light offshore from the ENE at 10 mph, so it’s clean. This is a solid option for a weekend session.

And if you can wait even longer, Thursday morning, the 24th of September is the standout of the whole window. We’ve got a 3 ft swell from the WNW, but the period is a very long 13 seconds, giving it a lot of push (239). The wind is a light offshore from the ENE at 10 mph, so it’s glassy. For a long period groundswell, this is the one to circle. It’s over two weeks away, but it looks promising.

So, if you’re looking for the best on offer, hit Sunday morning the 13th and Thursday morning the 24th. The rest is mostly small and messy, but that’s the Atlantic for you.

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.
