The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for the next couple of weeks.
To be straight with you, we’ve got a rough start. The first few days are pretty much a write-off. Thursday the 27th and Friday the 28th are a mess – onshore winds, weak, short-period slop, and that relentless cross-chop means you’re better off staying dry. The swell is tiny and messy, with combined energy values barely reaching 30 (28-31). It’s not worth paddling out for.
We finally see a pulse of energy arrive on Sunday the 30th. The morning shows a bit of hope with a 6ft swell from the WNW, but that period is a clean 11 seconds, which is decent. The combined energy pushes up to 692, which is a solid moderate energy. The wind is a light cross-shore from the SSW, which will keep things fairly clean. This is the best window in the near-term, but it’s still a marginal call. The afternoon turns choppy again as the wind goes cross-onshore.
Monday the 31st is another day of onshore wind and poor conditions, with the swell bumpy and messy. Tuesday and Wednesday are still not great, but Wednesday morning the 2nd of September shows a little light. We get a 3ft swell from the WNW with a cross-offshore breeze from the NNE, and the water goes clean. The energy is low (132), so it’s small, but it’s surfable. The next morning, Thursday the 3rd, is glassy. That’s a rare treat. The swell is tiny again at 2ft, period a short 8 seconds, but with glassy conditions and a combined energy of only 50, it’s about as small and clean as it gets. It’s a longboard or a fish kind of session.
The real standout, the one that catches my eye, is Saturday the 5th of September. The morning brings a 3ft swell from the WNW with a *very* long period of 12 seconds. That’s a proper groundswell. The wind is a clean cross-offshore from the NE. Combined energy is 260, which is moderate. This is a classic setup for Lacanau Ocean, which is an exposed beach break. The long period will mean better shaped waves, but it can also make beach breaks close out a bit. For a point or reef, this would be unreal. For here, it’ll be a lot more fun than the previous days. The afternoon stays clean with a cross-offshore breeze, but the period drops to 10 seconds.
Sunday the 6th keeps the clean vibes with a moderate offshore wind from the ENE and a 3ft, 11-second swell. Energy is low (177), but it’s clean. The rest of the second week sees a mix of clean mornings and onshore afternoons, with the swell holding around 3ft to 3ft. Nothing massive, but the conditions are more favorable for a paddle.
To sum it up: the first week is a struggle, but Sunday the 30th morning is a brief window of clean conditions. The real highlight is the morning of Saturday the 5th of September, with that long-period groundswell and clean offshore wind. It’s the best on offer. After that, the mornings look clean, but the swell is small. Keep your eyes on the weekend of the 5th.
Stay stoked, and keep your wax fresh.

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.
