Boucau Surf Forecast and Surf Report

We’re starting off with a dead stretch—nothing rideable until Thursday morning, August 6th. The first few days are just small, weak slop with cross-onshore junk, so don’t even bother. Thursday morning at Boucau (Aquitaine) has a little 3ft NW swell with a 9-second period, clean under a light cross-offshore breeze. Combined energy is moderate at 126, but it’s weak overall—surfable, but you’ll be scratching for waves. Friday morning, August 7th, is totally glassy with 3ft of short-period NNW windswell (66 weak energy)—better than nothing, but still pretty ordinary.

Then we hit a flat, frustrating spell from Friday afternoon through the middle of next week. Lots of poor surf, tiny waves, onshore mush. August 12th Wednesday morning shows a small pulse at 4ft WNW but it’s only 5-second period—just bumpy whitewater, not worth the drive. The 13th and 14th drop back to 2ft dribble. Honestly, this is a rough patch.

The first real standout shows up on Sunday morning, August 16th. Swell jumps to 4ft NW with a 10-second period and combined energy jumps to 299—moderate but building. It’s still onshore from the west, so it’ll be lumpy, and tide is questionable. Not perfect, but it’s the strongest signal we’ve seen yet. Monday the 17th is more of the same, just a bit smaller.

Then the big one. Tuesday morning, August 18th: 8ft WNW swell with a 9-second period and energy at 905—strong. Wednesday morning, August 19th: 7ft NW swell, 11-second period, energy at 1089, even stronger. This is the real deal. But listen—8ft is expert territory. Period is decent but not super long, and wind is onshore from the west/southwest. It’s not clean, this is going to be heavy, raw, and probably closing out at the beach. This is not for beginners, and even for seasoned surfers it’s going to be a battle. The combination of size and onshore wind makes this look more like a kite-surfing day than a relaxed paddle session.

Thursday morning, August 20th, things back off to 4ft NW with glassy conditions and moderate energy of 196—the most user-friendly day of the whole run, but still just average.

So here’s the deal: don’t get your hopes up for the first week and a half—it’s mostly flat or messy. The standout is the 18th and 19th for the big-swell crew, but it’s raw, powerful stuff. The 16th is your best bet for something clean-ish and rideable. And the 20th is the one for a comfortable, glassy session. Keep expectations low early, then suit up for the big pulse.
