The Lowdown
Alright folks, Rusty here. Let's get into what's looking like a bit of a mixed bag for our stretch of coast. We've got a solid 16 days of forecast ahead, but don't expect a classic September run from the get-go. There's a few windows where it'll clean up, but you'll have to pick your moments.
Right off the bat, we're looking at a pretty flat and messy start. The first real hope doesn't appear until the morning of Friday, the 11th of September, so be prepared for a few days of small, chopped-out slop before that. The water's sitting at a very warm 74°F, which is much warmer than normal for this time of year – definitely a wetsuit-optional vibe if you're brave.
Now, for the standout window. The morning of Sunday, the 13th of September is where things get interesting. The wind is light and offshore from the NNE, and we've got a clean, 2ft swell with a 13-second period. That's a proper groundswell pulse, and while it's not huge, the clean conditions and long-period energy will make for some really fun, lined-up waves at Lacanau Ocean. The moderate combined energy (275) tells you it's got enough grunt. This is your best bet early on. Monday the 14th morning is a very similar story with clean, cross-offshore wind and a 3ft, 12-second swell – another solid session to pencil in.
Moving into the second week, there's a promising pulse arriving on the morning of Friday, the 18th of September. We're looking at a bigger 5ft swell from the WNW, combined with a light cross-offshore breeze from the NNE. The combined energy jumps right up to 573, which is a serious amount of power. This is for experienced surfers only, as anything over 5ft is too much for beginners, but for the crew who can handle it, it's going to be a ripper morning at Lacanau Ocean.
The weekend of the 19th and 20th still has some decent waist-to-chest high waves, but the winds get a bit trickier. The morning of Saturday the 19th looks clean with a cross-offshore breeze and 4ft swell, so there's still fun to be had.
Overall, don't be fooled by the flat start. There are two clear standout windows: the clean, long-period groundswell on the 13th and 14th, and the bigger, powerful swell on the 18th. Just watch the wind shifts and you'll score.
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.
