The Lowdown
Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks here at Lacanau Ocean.
The first few days are a total write-off, I'm not gonna lie. We've got a consistent, but messy, 4ft of west-northwest swell, but it's being torn apart by cross-onshore winds. The water is a very unusual 74°, which is a solid 5° warmer than it should be for this time of year, so it feels like a summer holdover.
We need to wait until Thursday the 10th for the first real chance. On Thursday morning, a clean 3ft swell from the west-northwest rolls in with a light offshore breeze. The wave energy is still modest (182), but it’s clean. That window is very short-lived though, as the wind swings onshore by the afternoon and washes it out. Friday and Saturday are just small and average, with hardly any energy to speak of – we’re looking at combined energy figures in the 50s and 70s, which is essentially flat.
The highlight of this whole forecast comes on the morning of Sunday the 13th. We get a 4ft groundswell from the west-northwest with a long 13-second period, loading up a solid 476 units of energy. The wind is glassy, dead calm. That’s the morning to be out there. The session will be clean, lined-up, and punchy for the size. The period is long enough that the sets will have some good power, and the gaps between them will make the paddle out a breeze. It won't be too big, so it's a good one for the intermediate crew.
After that high, things drop off again. The morning of Monday the 14th is clean with a 4ft swell, but the energy is half what it was on Sunday. The following week is nothing special – small, chopped up, or just tiny. A few windows of clean conditions pop up here and there, but the swell is just too small to get excited about.
The final real standout is way out there, on the morning of Wednesday the 23rd of September. It’s a long way off, so keep an eye on it, but it shows a 3ft swell from the west with a very long 14-second period and a clean offshore wind. The energy reading is 303, which is decent for that size. The period is long enough that it could be a bit straight at the beach, but with offshore winds, it could be absolutely perfect.
Forget the afternoons, they’re almost all blown out. The first week is rough, but we've got a couple of solid mornings to aim for if you're patient.

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.
