The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line for us at Lacanau Ocean. The next couple of days are pretty lackluster, so don’t rush out just yet. There’s a bit of waiting to do, but a solid window opens up around Saturday the 5th that looks worth circling on the calendar.
We’re starting off with a bit of a tame, ordinary stretch. Thursday morning offers tiny 2 ft surf from the WNW with an 8-second period and only a combined energy of 40, but the wind is glassy from the ENE at 3 mph. The water is sitting at 74°, which is a touch warmer than normal for this time of year – a nice little bonus. It’s surfable, but hardly worth calling in sick for. Thursday afternoon and Friday keep that same small, weak trend with poor conditions as the wind swings cross-shore. Friday morning stays glassy again with 3 ft waves, but it’s still very ordinary.
Alright, now here’s where it gets interesting. Saturday the 5th is your standout window. The morning shows a clean, cross-off breeze from the NNE at 6 mph, with 2 ft waves but the period jumps to a juicy 14 seconds. That’s a proper groundswell with 318 combined energy, and it’s gonna offer some shape. But the real gem is Saturday afternoon: the swell bumps up to 4 ft from the WNW with a very long 13-second period and a combined energy of 560. Winds stay light cross-off from the NNE, so it’ll be clean. This is the best on offer, folks. A long-period groundswell like this will line up beautifully at this exposed beach break, though keep in mind that at really long periods it can get a bit straight at a beach, but Lacanau can handle it. This is for intermediates and up; beginners might find the push a little strong.
Sunday the 6th goes downhill quickly with a risk of thunderstorms, onshore winds up to 16 mph, and messy surf. By Monday the 7th, we’ve got a small 2 ft swell in the morning with a strong 14-second period but onshore wind, making it a poor choice. The middle of the week from the 8th to the 13th is a grim run of cross and cross-onshore winds with mostly weak, short-period swell and low energy – nothing worth paddling out for. Wind speeds hover between 6 and 16 mph and the surf stays below 5 ft, but the wind just kills it.
We finally get a glimmer through the second week. Thursday the 17th morning brings a clean offshore breeze from the E at 9 mph with 2 ft waves and an 11-second period. Very ordinary again, but at least it’s clean. Then Friday the 18th morning is similar with offshore ENE winds and 2 ft surf – tiny but workable for a longboard or a quiet session. The energy numbers are low (47-80), so don’t expect anything spectacular.
Overall, the entire 16-day window is pretty flat and wind-affected outside of that Saturday peak. There are several days with no surf worth recommending. If you’re jonesing for a wave, hold out for Saturday afternoon the 5th. It’s the clear winner.
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.
