The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way for Lacanau Ocean over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a long, slow burn. The first week and a half is pretty grim. We’re looking at a real dry spell with next to no surf on offer until the very end of the forecast. The ocean is teasing us, but there’s nothing rideable for the first ten days or so. A few small bumps show up, but the wave comment says it all: poor surf conditions. You’d be wasting your time.
The first real glimmer of hope doesn’t arrive until Tuesday morning, September 8th. Even then, it’s only marginal – a small 4ft swell from the WNW with a 10-second period, but the wind is cross-onshore, so it’s not clean. The combined energy is a moderate 383 (moderate wave energy). Then on Tuesday afternoon, we get a very long period 17-second groundswell, but it’s tiny at 2ft from the W. That’s a classic setup where the period is incredible but the size just isn’t there. Combined energy is 515 (moderate wave energy). Still, both days are listed as marginal.
Now, hold on to your board, because the standout window is Wednesday morning, September 9th. This is the one. We’ve got a clean 5ft groundswell from the WNW, with a solid 13-second period. The combined energy is a strong 874 (strong wave energy). But the real kicker – the wind is glassy. Absolute zero. That’s a major positive. The wave comment says “expect very good surf conditions.” This is your best bet. Get out there early. The water temperature is 76°F, which is about 5°F warmer than normal for this time of year, so that’s very unusual – you’ll be in a warm bath. The break is consistent and exposed to the W swell, which the guidance says is the optimum direction. The crowd factor is “sometimes,” so expect some company.
The Wednesday afternoon session drops off a bit with a cross-onshore wind, so it’s back to marginal. Thursday morning, September 10th also goes back to poor conditions.
So, to sum it up: the first week is a write-off. Don’t bother. The only real standout is the morning of Wednesday, September 9th at Lacanau Ocean. That’s the one to circle on the calendar. It’s a long-range call, so keep an eye on it, but the signals are strong.
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.
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.
