The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Lacanau Ocean.
Honestly, it’s a pretty grim outlook for the next couple of weeks. The first few days are a write-off. We’ve got a bit of small swell trying to push in on Wednesday the 5th, but it’s a weak 2ft from the WNW with a nasty cross-onshore wind, and the combined energy is only a weak 60. The water is sitting at 76°, which is a full 5° warmer than usual for this time of year – that’s really unusual and feels like bathwater.
Thursday the 6th is a little better size-wise, hitting 3ft Thursday morning, but again the wind is messy and cross-shore, making it choppy. Not worth paddling out for. The energy is still weak at 102 (moderate) but it’s just not clean.
Friday morning the 7th is the closest thing to a highlight we’ve got in the first week. The swell is tiny at 2ft NW, but an easterly wind of 5 km/h is making it glassy. It’s surfable, but just barely. The energy is only 52, so it’s weak. For a true beginner, this might be a fun little mushburger, but there’s no power.
After that, the whole stretch from Saturday the 8th through to Wednesday the 13th is a total flat spell. We’re talking days of 0.7ft to 2ft with poor or ordinary conditions. The wind is all over the place – onshore, cross-on, you name it – and the energy rarely cracks 100. It’s a long, boring gap.
The first real sign of life comes on Saturday the 15th. The morning shows a 4ft NW swell, with a combined energy of 212 (moderate). The wind is a gentle cross-shore from the north, so it’s not a total mess, but the forecast calls it marginal. The period is short at 8 seconds, so it’ll be a bit fat and lumpy. Again, not a standout, just the best of a bad bunch.
Sunday the 16th is a write-off – strong onshore wind and a tiny 2ft NW swell with a terrible 5-second period. Energy drops to 41. That’s a kite-surfing day if you’re into that, not a paddle day.
The only other blip worth mentioning is Thursday the 20th. The swell is a small 2ft from the WNW, but the wind is a clean cross-offshore from the NNE at 10 km/h. The energy is 88 (weak), but the conditions are described as clean. If you’re desperate, you could get a few little runners on the inside. But it’s still nothing to write home about.
Overall, the entire 16-day window is a dud. There’s no standout, no proper swell, and the wind is almost always working against you. For Lacanau, this dry spell is a bit more normal in the summer, but it’s still a tough one to swallow. Keep your eye on the charts, because it won’t stay this poor forever.
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.
