Alright folks, Rusty here. Let's have a look at what's on the menu for Lacanau over the next couple of weeks.

We're starting off with a bit of a flat spell, I'm not gonna lie. The first proper surf we see is a small one on Sunday morning the 12th of July. The water is a very unusual 77°F, which is a full 8°F warmer than what we’d expect for this time of year – that’s pretty wild, but it’s the only thing that’s firing that day.

The early part of the week is looking pretty grim. There's a whole lot of 0.7ft to 3ft of junk with messy cross-onshore winds and short period windswell. The energy is weak (49 and below) and the scoring is just not there. It’s a write-off until we get a little window of hope.

On Monday morning the 20th of July, we get a bit of a reprieve. It’s a tiny 2ft from the NW with a 7-second period, but the wind is a clean offshore from the ENE. The combined energy is only 62, so it’s not a standout, but it’s surfable and clean. If you’re desperate and have a log, this is your window.

The real standout, though, is much further out. Hold onto your boards. On Thursday the 23rd of July, we’ve got a solid pulse of swell. The morning sees a 7ft W swell with a 7-second period and a combined energy of 429. The afternoon builds even more to 7ft from the W with an 8-second period and a whopping 609 energy. That’s a strong pulse of energy. The wind is a cross-onshore (WNW) at 9 mph, which isn't ideal, but the size and energy are undeniable. This is expert territory, though; 7ft is too big for beginners. The period is shorter than ideal, so expect some lumpy, raw waves rather than perfect lines, but it’s the biggest and most powerful action in the entire 16-day window. For the experienced crew, that’s the session to target.

The following Friday the 24th is still punchy with 5ft to 4ft, but the wind picks up to 16 mph, making it a choppy mess. The energy is still moderate (328 and 234), but the quality drops off a cliff.

The last chance for a clean wave comes on Sunday the 26th of July. The morning is glassy, dead flat wind, with a 2ft WNW swell. The energy is low (54), but you can’t beat a glassy morning for a small summer fun-sesh. Then on Monday the 27th of July, the morning is clean again with a light ESE wind and a 3ft WNW swell, energy at 132. It’s not a stand-out for size, but it’s a clean, ridable option.

So, to boil it down: ignore the first week of small, choppy rubbish. The one true standout is the big pulse on Thursday the 23rd of July, but it’s for the hardcore guys only. For clean, small waves, aim for the 20th of July morning or the glassy morning of the 26th of July.

Catch you on the beach.

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.
