The Lowdown
G'day, Rusty here. Alright, let's have a proper look at what's coming down the line at Lacanau Ocean over the next couple of weeks. There's a fair bit going on, but you've got to pick your moments.
The first half of this run is a bit of a mixed bag, with small to moderate waves and the wind making things tricky more often than not. The standout is looking to be next Sunday morning, the 20th, but keep an eye on the 22nd and 23rd as well.
Let's start with this Thursday, the 10th. We get a glassy start to the morning with a 3ft west-northwest swell, period of 10 seconds, and a combined energy of 182 (moderate). That's surfable for sure, but water temps are sitting at 73°, a solid 4° warmer than usual – that's notably warm for the time of year. By the afternoon, the wind swings northwest and goes cross-on, messing things up with 2ft waves. Friday the 11th is tiny – 2ft in the morning with glassy conditions, but there's just no juice. Saturday the 12th offers clean 3ft waves in the morning with a cross-offshore breeze, so a few small ones if you're keen.
Now, Sunday the 13th is where we start to see some life. The morning brings a clean 4ft west-northwest swell, a long period of 13 seconds – that's proper groundswell – and combined energy of 415 (moderate). That'll have some shape to it. The long period might make it a bit straight at this beach break, but the cross-offshore wind should help. Monday the 14th is similar in the morning: 4ft, 11-second period, clean again, with 260 (moderate) energy. Tuesday the 15th and Wednesday the 16th are pretty average, with onshore or cross-on winds and chop.
Thursday the 17th morning is marginal – 4ft and 11 seconds, but a cross-shore wind. Not really one to plan your day around. Friday the 18th and Saturday the 19th are mostly small or messy.
Here's the first real standout: Sunday morning, the 20th of September. The swell jumps to 7ft from the west-northwest, with a short period of just 6 seconds, but combined energy is 299 (moderate). Don't let the short period fool you. The wind is glassy out of the northeast – dead calm, 3 mph. That's about as clean as it gets. The waves will be a bit fat and crumbly with that period, but for a beginner-friendly, clean 7ft day at a beach break, this is solid. It's big enough to be fun, but not too big for competent intermediates. Crowds are sometimes an issue here, so you might have company.
Now, the next one is a big boy, but it's only for the experts. Monday morning, the 21st of September – we're looking at a massive 10ft groundswell from the WNW, with a period of 10 seconds and combined energy of 1697 (very strong). The wind is glassy again, 3 mph from the north-northeast. That is a lot of water moving. At over 8ft, this is expert territory only. The swell direction is west-northwest, right on the money for the optimum. The size and power will be intimidating for most, but for those who can handle it, the conditions will be pristine. Stay safe out there.
For the following week, the quality holds. Tuesday morning, the 22nd of September, we get clean conditions again with a north-east cross-offshore breeze, 5ft swell from the WNW, a 12-second period, and combined energy of 658 (moderate). Plenty of punch and good shape. Wednesday morning, the 23rd is a carbon copy – 5ft, 11-second period, cross-offshore wind, energy of 613 (moderate). Both of these mornings are excellent options for a decent session.
Thursday the 24th morning is glassy with a 4ft swell, energy of 432 (moderate) – a nice small-wave day. Friday the 25th morning has a 5ft, 14-second period swell, energy of 933 (moderate), but a cross-shore wind keeps it from being top-tier.
So to sum it up: if you want the best on offer, set your alarm for Sunday the 20th morning – that's the one for the clean, sizeable fun waves. If you're a more experienced surfer looking for power, Monday the 21st morning is the power session for experts only. For the best all-round, consistent quality, target Tuesday the 22nd and Wednesday the 23rd mornings.
Stay stoked, and I'll see you out there.

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.
Lacanau Ocean is 38 km (24 miles) from Arcachon. If you plan a holiday in Gironde, look for hotels and other accommodation in Arcachon. Arcachon has rooms for a wide range of budgets as well as car hire and transport links.
