The Lowdown
Alright, Rusty here, breaking down the surf for Hossegor – La Graviere over the next couple of weeks.
First few days are pretty flat and messy. Friday morning the 4th has a tiny 2ft swell from the WNW with a short 9-second period, combined wave energy only 80, and the water is 74°—way warmer than usual for early September. That glassy condition is a tease. Friday afternoon goes cross-on, so nothing doing.
Saturday the 5th morning is the first real session: 3ft from the WNW with a light offshore east wind at 6 mph, clean faces, and energy up to 233. Good for a grovel board. Saturday afternoon jumps to 5ft from the NW with a 13-second period and 734 energy, but a north cross-shore wind puts a little bump on it—still workable for advanced guys.
Sunday the 6th morning has 5ft NW swell, 12-second period, but a light cross-onshore from the northwest takes the shine off. Energy is 551. Afternoon is onshore junk.
Monday the 7th morning is no good—2ft of 16-second groundswell is too long period for a sandbar with onshore wind, combined energy 272. The rest of the week through Friday the 11th stays poor with onshores and rain, energy dropping as low as 125. Not worth the paddle.
Saturday the 12th afternoon goes glassy again but it’s only 3ft NW with 9-second period and 173 energy—small and ordinary.
Then Sunday the 13th morning lights up: 5ft NW swell, 11-second period, offshore east-northeast wind at 9 mph, combined energy 471. This is the first real standout—clean, powerful, and lined up. Get out early before the wind swings and ruins it by afternoon.
Monday the 14th morning is another decent window: 3ft NW, 11-second period, cross-offshore wind, energy 222. Clean but smaller.
The best of the whole run is Wednesday the 16th morning: 5ft from the NW, 10-second period, glassy calm with a light northeast breeze, combined energy 508. This is the biggest and cleanest swell in the forecast. After that, Thursday the 17th morning offers 4ft WNW with glassy conditions again—another clean session.
Crowds are listed as “sometimes” for La Graviere—on days like Sunday the 13th and Wednesday the 16th, expect plenty of company.
Rusty out.
