The Lowdown
G’day, Rusty here. Let’s talk about what’s shaping up for Lacanau Ocean. Honest truth – the next week or so is pretty flat and messy. Don’t rush to wax up just yet.
We start Wednesday, September 2nd, with nothing to ride – a tiny 3 ft swell from the WNW, weak 9-second period, and cross-onshore winds messing it up. Thursday and Friday are even smaller, 2 ft to 2 ft, and the energy is barely there (34 to 55 on the scale). Friday morning might look glassy, but it’s just too small to matter.
Saturday the 5th morning gives us a bit of hope – 3 ft from the WNW, period up to 9 seconds, and light cross-off winds keeping it clean. Energy hits 206 (moderate) and conditions are rated good. It’s small, but it’s the first real window. Afternoon gets hammered by 15 mph cross-shore winds. Sunday and Monday are onshore slop – 3 ft but windy and messy. Energy climbs to 363 and 423, but the quality’s poor.
The big one is Wednesday, September 16th morning. This is the session to aim for. A solid 5 ft swell from the WNW with a nice 12-second groundswell period. Combined energy is 629 (strong), and with a light cross-off breeze from the NNE, conditions are predicted to be very good. The swell direction (WNW) matches the break’s preferred W exposure. Clean, powerful, with proper lulls between sets. Best for experienced surfers – beginners will find it too big.
Thursday the 17th morning still has some juice – 4 ft from the NW, 11-second period, offshore wind from the ENE, and moderate energy (334). A good follow-up, but not the standout.
Water temp’s about average for the season at Lacanau Ocean – nothing unusual.
For the early days, it’s a slow grind. The Saturday the 5th morning is your best bet if you’re desperate. But the real gold is that Wednesday the 16th. Circle it, watch the forecasts, and be ready.
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.
