The Lowdown
Alright crew, Rusty here, switching to feet and inches. Let’s talk about what’s happening at Lacanau Ocean over the next couple of weeks. It’s a slow burn, but there’s a clean window you don’t want to sleep through.
The first week is pretty much dead. From Tuesday the 21st through to the end of July, we’re looking at tiny, weak swell with messy cross and onshore winds. The energy is pathetic, with combined swell energy readings mostly under 100 – just no grunt. You’ll see some bumpy, short-period wind slop, but nothing worth paddling out for. The water is a crazy 26°, which is 5° warmer than normal – that’s a very unusual, near-bathwater situation.
The one real bright spot lands on Tuesday morning the 28th of July. We’ve got a clean, light cross-off breeze from the NNE at 10 km/h, which will keep the surface glassy. Swell is 4ft out of the NW with a 10-second period. That’s a proper groundswell with moderate energy (269). The waves will have some shape and power, but it’s still manageable for most intermediates. The offshore wind is the whole story here – it’ll be clean and fun. It’s a consistent break, so you’ll get waves, but expect some company – it can get crowded. The optimum swell direction is W, and this NW swell isn’t a perfect match, but with those conditions, it’s your best bet.
After that Tuesday morning, the wind turns and the quality tanks again. Wednesday the 29th morning has a tiny 2ft clean wave, but it’s weak. Thursday the 30th morning is also clean but tiny at 2ft.
The second week, from the 1st of August, is back to small, short-period, wind-affected junk. Low energy everywhere, under 100. Swell direction is all over, and the wind is mostly cross-on or onshore. Nothing to get excited about. This spot is exposed and consistent, so it doesn’t usually stay this flat for long, but this run is looking grim.
So here’s the call: your only real shot is Tuesday the 28th of July, morning. Set the alarm, get the clean 4ft NW groundswell while the wind is off. The rest of the window is a bust. Keep an eye on it, but for now, that’s your one.
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.
