The Lowdown

Alright folks, Rusty here. Let’s have a good look at what’s comin’ down the line for Lacanau Ocean.

First thing you gotta know: the next week and a half is pretty grim. There’s energy in the water, but it’s all short-period, weak, and mostly cross-onshore or onshore, making a mess of things. The combined swell energy barely cracks three digits, and even when it hits 229 on Thursday 6th August afternoon, the period is only 8 seconds—that’s all windswell chop. We’re talking poor surf conditions day after day. The water temp is about average for this time of year, so no surprise there.

Honestly, the first real glimmer of hope doesn’t show up until Thursday 13th August morning. That’s the first “surfable” call we get, but it’s barely a 1 out of 10—just tiny 2 ft waves from the west at 9 seconds, with a light offshore breeze. Clean, but tiny. There’s a similar little window on Saturday 15th August morning, with 2 ft from the northwest and a clean offshore, but only 5 seconds of period. That’s a dribbler.

The best on offer in the whole 16 days? It’s Monday 17th August morning. Still not a classic, but it’s the standout. You’ll see 4 ft of northwest swell, period around 6 seconds, and a clean cross-offshore wind from the northeast. The combined energy hits 166—moderate, finally. It’s surfable, but with that short period, it’s a bit soft and lumpy. Still, given the rest of the forecast, that’s about as good as it gets. Crowds are possible here, so expect company.

Everything else is either close to flat or blown out. If you’re a kiter, the afternoons with 16 mph cross-shore winds might be more interesting than paddling.

Bottom line: don’t get your hopes up for the next two weeks. The 17th morning is the one to pencil in, but keep an eye on it—long-range calls can change.

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.
