The Lowdown
Hey, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty flat and uninspiring for most of the region. We’ve got a long stretch of small, weak surf ahead, and it’s going to take a while before anything worth getting excited about shows up.
The first real opportunity, and honestly the standout of the whole window, is on Saturday the 16th. The swell starts to build through the morning, with waves around 4ft coming from the WNW. The energy is moderate (226) and it’s a light cross-onshore breeze, so it won’t be perfect, but it’s the most size we’ve seen in a while. The afternoon drops slightly to 3ft but the energy is still there (180). It’s not epic, but it’s the best on offer.
Things get properly interesting the following Tuesday, the 18th. A solid pulse of WNW groundswell fills in, with the morning seeing 8ft waves and the energy jumping to a strong 755. The problem is the wind. It’s a cross-onshore in the morning, turning fully onshore by the afternoon. The morning might be rideable for the experienced crew, but it’s going to be lumpy and challenging. The afternoon pushes up to 8ft (1044 energy) but with that onshore wind, it’s going to be a messy, powerful beast. This is expert-only territory, and even then, it’s not going to be pretty.
After that, the swell backs off again. Wednesday the 19th still has some size – 6ft in the morning (561 energy) – with a light cross-shore wind, which could be a slightly cleaner, though still powerful, option for those who know what they’re doing. But by the afternoon and into Thursday the 20th, it fades back down into the ordinary stuff.
For the weeks before that, from now until the 15th, it’s a write-off. We’re looking at waves mostly under 3ft, with weak energy and onshore or cross-shore winds messing up what little is there. There will be a few glassy mornings, like the 7th and 11th, but with only 2-3ft on tap, it’s barely worth paddling out for. The break itself, Lacanau Ocean, is a consistent spot, but it needs swell to work, and it just isn’t there.
So, mark your calendar for the 16th for a fun session, and keep an eye on the 18th if you’re a proper charger. Otherwise, it’s a good time to clean the wax off your boards and wait.

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.
