The Lowdown

Alright, Rusty here. Let's be straight with you. The next couple of weeks are a bit of a mixed bag for Lacanau Ocean. We've got some swell coming, but the wind is going to mess with things more often than not. Don't expect to be scoring epic barrels every day, but there are a few windows where it could come together.

The next few days are pretty grim. Wednesday the 26th has a touch of swell, but it's tiny, weak, and the energy is barely there (27). It's a write-off. Thursday sees a slight bump, but it's short-period, junky stuff from the west-southwest, with poor conditions. We get a pulse of energy Friday the 28th, with the swell pushing up to 7ft, but the wind is howling onshore and the period is short. That's a messy, blown-out day, not worth your time.

The weekend isn't looking much better. Saturday the 29th has a moderate amount of energy (393) but it's onshore, choppy, and just plain poor. Sunday the 30th, there's a bit of a jump in the swell with a 5ft west-northwest groundswell, and the energy is up there (496), but the morning is only marginal and the afternoon gets chopped up. Monday the 31st is similar – some size there (6ft) but the conditions are only marginal at best.

We finally see a glimmer of hope on Tuesday the 1st of September. The swell drops a bit to 4ft, but the energy is still moderate (253) and the wind goes cross-shore. The morning is only marginal, but it’s a step in the right direction. The real standout in this whole window is Wednesday the 2nd of September. The swell is small at 3ft, and the energy is dialed way down (121), but that morning it goes glassy with a slight air from the north-northeast. It might not be big, but it'll be clean and lined up. That’s your best bet for a real surf.

After that, we slide back into ordinary conditions for a while. The middle of the first week of September is pretty weak. Thursday the 3rd has a bit of clean surf in the morning, but it's small. The rest of that period gets chopped by the sea breeze. We get another chance on Saturday the 6th, with a clean early session but the wind picks up and ruins the afternoon. Same story for Monday the 8th, where there's a bit more size at 4ft but it's only marginal.

Looking further out to the 10th and 11th of September, the outlook is pretty weak. The swell is small, the energy is low, and the wind is onshore most of the time. There's nothing on the horizon that looks like a proper swell, so the last few days of the forecast look like a bit of a dry spell. To be honest, if you're looking for a good wave, you've got to nail that glassy Wednesday the 2nd. It won't be huge, but it'll be clean.

So, for the pick of the fortnight, it's got to be Lacanau Ocean (France) on the morning of Wednesday, September 2nd. Paddling out into those clean, small conditions will be a treat after all that wind we're going to have to sit through. It’s a long way out and a long way from being set in stone, so keep an eye on the forecasts as we get closer.

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.
