The Lowdown

Alright, let me break this down for you. The surf scene here at Lacanau Ocean is looking pretty flat and quiet for the next couple of weeks, to be honest. Most of the time, the conditions are just poor, with small, weak swells and messy winds. There's no real standout, but let's see if we can find a sliver of hope.

The overall pattern is one of small, weak, and often choppy surf. The combined energy of the swells is mostly in the low double digits, like 43 and 40, which is really weak, right up until the second week of August. The water temperature is sitting at 71°, which is only 0.5° above normal, so it's pretty average for this time of year. The wind is a problem too, frequently cross-on or onshore, keeping things messy.

For the first week, from Thursday the 30th of July right through to the weekend of the 9th and 10th of August, it's just a run of poor surf. Tiny swells, mostly under 3 ft, combined with that cross-onshore wind. It's going to be a frustrating wait. There's a gap of about 11 days with no real recommendations.

Now, the first glimmer of anything decent comes on Tuesday the 11th of August. The morning session at Lacanau Ocean has a little 3 ft swell from the NNW, but the real story is the wind. It's glassy, mate. Absolutely glassy. The combined swell energy is still only 57, so it's weak, but those clean, glassy conditions will make it surfable. It's still just "surfable waves but very ordinary conditions" though, so don't expect any barrels. The afternoon gets choppy again.

Looking further out, the morning of Friday the 14th of August has a tiny 1 ft swell from the WNW with a bit more period at 10 seconds, and the wind is a light cross-offshore breeze. The combined energy is a weak 44, but it's clean. Again, it's only "surfable waves but very ordinary conditions." It's a long shot, but if you're desperate for a clean, small wave, that's the pick.

Given the lack of size and the persistent onshore winds, a lot of this setup looks more interesting for a kite session than a paddle session, especially when the wind is up and the swell is small and weak.

The best on offer is probably the glassy morning of Tuesday the 11th of August, just for the cleanliness, even if the waves are small. The second-best is the clean, light breeze morning of the 14th.

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.
