The Lowdown
Alright, Rusty here again. Let's break down the same outlook but in the old money.
So, looking at Lacanau Ocean, it’s a tough one to call. The first week and a half looks like a total bust, with hardly any clean, rideable waves. The water is a warm 76°, which is a good 5° warmer than usual for this time of year, which is a real shame the surf isn't cooperating.
We kick off with a pulse of swell, around 5ft from the WNW, but it’s ruined by a strong cross-onshore wind on Friday the 21st. The energy is moderate (394), but it’s just messy. The only real glimmer in the first week is a brief window on Saturday morning the 22nd. The swell drops to 3ft from the WNW, but the wind goes light and offshore from the East. The combined energy is weak (151), but it’ll be clean. The problem is, it’s really just a last resort for a paddle.
The rest of that week and into the next is a write-off. We’ve got a mix of onshore winds, tiny swell, and on the 27th and 28th, the swell jumps up to 8ft and 6ft, but with strong onshore winds (up to 22 mph), it’s just a washing machine. That 8ft on the 27th with 724 energy is a lot of power, but it’s expert-only chaos in those conditions. Honestly, for a beach break like Lacanau, that setup looks more interesting for kite surfing than paddle surfing.
The one standout, and I mean the *only* one worth getting excited about, is a long-range whisper. It’s a bit of a gamble, but check out Thursday morning, September 3rd. We’ve got a solid 8ft swell from the W with a moderate 9-second period, and the combined energy is a strong 769. Now, the wind is forecast to be onshore, which is a risk, but models change. If that wind backs off even a little, this could be a proper session. It’s big, so it’s for experienced surfers only, but the potential is there. The Friday morning the 4th after that also has a 5ft swell from the WNW, but it’s a similar story with the wind. So, keep your eyes on the 3rd of September. It’s a long way out, but it’s the only real promise on the board.
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.
