The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for the next couple of weeks at Lacanau Ocean (France).
Right now, the vibe is pretty flat and quiet. For the first several days, we’re looking at tiny waves, mostly around 1.0 ft to 2 ft with weak combined swell energy (between 39 and 71). The wind plays nice in the mornings with some glassy conditions, especially on Sunday 9 August, Monday 10 August, Tuesday 11 August, and Wednesday 12 August. Those early windows offer clean, smooth conditions but the swell is just too small to get excited about – surfable but very ordinary.
Things start to pick up a bit from Thursday 13 August onward, with swell heights slowly creeping up. By Thursday 13 August morning, we’ve got 2 ft from the west, period at 9 seconds, and glassy wind. The combined energy is still low at 87, so it’s not punchy, but it’s a step up. The water temperature is about average for this time of year, nothing unusual.
Friday 14 August and Saturday 15 August bring more of the same: waist-high slop at best, with onshore or cross-onshore winds turning it messy in the afternoons. The combined energy stays under 130, so it’s weak.
The real shift comes on Friday 21 August. The swell jumps to 4 ft in the morning and 5 ft in the afternoon from the northwest, with a period of 11 seconds. Combined energy hits 375 in the morning and 496 in the afternoon – that’s moderate to strong energy. But here’s the catch: the wind is cross-onshore at 12 mph, so the quality is poor. This is more of a raw, powerful ocean than a clean wave. It’s going to be choppy and hard work. For experts only if they’re keen on a battle, but honestly, the setup looks more interesting for kite surfing than paddle surfing with that wind and swell combo.
Saturday 22 August morning still has some size at 4 ft from the WNW, period 9 seconds, combined energy 236, and lighter onshore wind. It’s marginal – could be okay if the tide plays ball, but don’t expect perfection.
Beyond that, from Sunday 23 August onward, the swell fades quickly back to knee-high and weak, with poor wind conditions. A real letdown after that one burst of energy.
The one standout window is the morning sessions between Sunday 9 August and Thursday 13 August – glassy, clean, but tiny. If you’re desperate for a longboard or a foamie, those are your moments. The bigger pulse on 21 August is powerful but too messy to recommend for a good time.
So, Lacanau Ocean is looking pretty flat and quiet for the next two weeks, with only a brief, messy window of size. Not the best run for the area – it tends not to stay poor for long, so keep an eye on the forecasts.
Stay tuned,
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.
