The Lowdown

Alright, Rusty here. Let's take a look at what's on the cards for the next stretch.

Right off the bat, I gotta be straight with you – this is a tough one. The forecast for the next 16 days is a real desert for surf. We're looking at a long run of tiny, weak, and mostly blown-out conditions. The first recommendation for a surf isn't even until the morning of August 9th, so that's a solid 10-day gap with nothing worthwhile to report.

The water is a big talking point if you do get in. It's sitting at 76°F, which is a whopping 5°F warmer than usual for this time of year. That's a noticeable, pleasant surprise.

Let's walk through the handful of moments that might offer a paddle. The only real standout I can see, and I'm clutching at straws here, is the morning of Sunday, August 9th at Lacanau Ocean. We've got a tiny 3 ft swell from the west with a 9-second period, giving it a combined energy of just 99 – that's weak. But the wind is light and offshore from the east, making for clean conditions. We're talking about a knee-high wave, but it's clean. The best on offer? Yeah, it's the best on offer. It's a very poor choice, but it's the only one.

Then, on Monday morning, August 10th, we have a similar story. A 2 ft west swell with an 8-second period (energy 50), and a light cross-offshore breeze from the northeast keeping things clean. Again, tiny, but clean.

For the rest of the period, through to August 15th, it's a mess. The wind is mostly cross-onshore or onshore from the north-west, with speeds kicking up to 12-16 mph, making the small surf messy and choppy. The swell is consistently under 3 ft, with periods bouncing between 4 and 10 seconds. Even the morning of August 12th, with a 2 ft west swell (68 energy) and onshore wind, is a washout. The same goes for the last few days – rain showers on the 13th and 15th, with onshore winds and a tiny, weak swell.

Honestly, for this stretch, the conditions are so poor for surfing that it's worth noting the wind and wave setup on many of these days looks more interesting for kite surfing than paddle surfing. There's just not enough power or shape for a proper surf.

So, keep your expectations low. The forecast can change, but right now, it's a waiting game.

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.
