The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the line for our next couple of weeks at Lacanau Ocean.
We're looking at a bit of a slow start, but there's a couple of proper windows of fun on the horizon. The first few days are pretty messy, with a lot of onshore wind and choppy surf. The water temp is sitting right around average for this time of year, so nothing weird going on there.
The first real chance to get a clean wave doesn't come until Thursday morning, the 10th of September. The swell is a modest 3ft from the WNW, but the wind is going glassy. That's the magic word. It'll be tiny, but clean as a whistle. The combined energy is moderate at 203, so don't expect a lot of power, but for a small board or a longboard, it'll be a lovely session with no crowd hassle.
The standout window, however, is a bit further out. Mark your calendars for the morning of Thursday, the 17th of September. The swell picks up to a solid 6ft from the WNW, and the wind is a clean offshore from the ENE. The combined energy is a strong 540, so there's real grunt behind it. The period is 10 seconds, so a nice, punchy, workable wave. This is the one you want to be free for. The morning will be the pick – the afternoon gets a bit chunky with the cross-shore wind.
After that, there are a few more mornings with offshore winds, but the swell drops away. The morning of the 22nd of September has a clean 2ft from the west with an offshore easterly, which is a nice way to finish the run, but it's pretty small.
So, to sum it up: the first week is a write-off for the most part, with only the glassy Thursday morning the 10th offering a clean, small wave. The big one to aim for is the Thursday morning the 17th, with a solid 6ft groundswell from the WNW and glassy offshore wind. That's your best bet.
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.
