The Lowdown
G'day, Rusty here, checking in from the coast. The next two weeks look like a bit of a mixed bag with some real potential if you're patient and keep an eye on the long-range forecast.
We're starting off with a quiet stretch. The first few days are a write-off for any decent waves. The water temp is sitting at 78°, which is a solid 7° warmer than usual, so it's a lot warmer than typical for this time of year.
Things start to look interesting on the morning of Saturday the 22nd. The wind swings light offshore from the east, and we get a clean window with small 3ft swell from the WNW (9 seconds). The energy is weak (147), but it's the only clean option in the first week. It's surfable, but nothing to get too excited about.
From Sunday the 23rd through to the end of August, it's a real struggle. The swell drops off, the wind turns onshore or cross-shore, and we get a long run of poor surf with the energy dipping as low as 12 on Tuesday the 25th. There's a brief uptick on the morning of Wednesday the 26th with clean conditions and 3ft swell, but it's still weak (79). Honestly, it's more of a kitesurfing setup than a paddle surfing one during this period.
The real standout, and the one to mark in your calendar, is the morning of Thursday the 27th of August. We get a big 10ft swell from the west with a 9-second period. The combined energy is a massive 1165, which is very strong. The wind is a gentle cross-onshore, and the forecast says wind and tide are favorable. However, this is going to be a big, powerful swell – way too big for beginners and only for experts. The only catch is that the afternoon kicks up a strong 25 mph onshore wind, so you'll want to be out there early.
After that, the wind stays onshore and strong for the rest of August and into early September, with the swell dropping back to the 3ft to 7ft range. It's a messy stretch.
The next promising window comes on the morning of Thursday the 3rd of September. The wind is a light cross-offshore from the NNE, conditions are clean, and the swell is a solid 6ft from the west (7 seconds, short period). The energy is moderate (310). This is the best bet for the second week.
Following that, the morning of Friday the 4th of September looks good too. A light offshore from the ENE, clean conditions, and a 6ft swell from the WNW (8 seconds, moderate energy of 366). This is another solid option.
Overall, the two standout sessions are the morning of the 27th of August for the big wave crew, and the morning of the 4th of September for a more manageable, clean session. The rest of the period is full of onshore wind and poor conditions.
Rusty, signing off.

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.
