The Lowdown
Alright, let’s break it down for the imperial crew. Seignosse - Le Penon, here we go.
First things first – the next seven or eight days are a bust. Super small, mostly dirty wind, and barely any energy to work with. The numbers tell the story: combined swell energy in the teens and twenties (weak), slowly climbing through the hundreds (moderate), but it never lines up right. You’re looking at mostly 2-3ft slop with cross-shore wind. Don’t bother.
Then Friday morning, August 21, things finally turn. A solid 5ft of NW groundswell rolls in with a 10-second period, and the wind swings light offshore out of the NE. The energy hits 408 (moderate) and it’s clean. That’s your golden window. Water temp is 76°, which is nearly 5° warmer than the long-term average – way unusual and very welcome.
After that, Saturday morning, August 22 holds 4ft of NW swell with a light east offshore – cleaner but smaller. Then the tail end of the month throws a bigger but less clean swell: Sunday August 30 sees 5ft of NW swell with an 11-12 second period, pushing the energy up to 669 (strong). But the wind is onshore or cross-on, so it’ll be lumpy. That’s one for the experts only, and even then, it’s dicey.
Stick with Friday morning, August 21. Everything else is a maybe.
