The Lowdown
Alright, listen up. Rusty here with a look at the next couple weeks for Hossegor – La Graviere. It's a bit of a slow start, but there’s a window of proper swell and clean conditions that’s the main event.
We've got some okay surf straight away. This Sunday morning, 13th September, brings 4 ft of NW groundswell with a very long 13-second period. The combined energy is a strong 501, and with a glassy wind from the SSE at only 3 mph, that’s a beautiful, clean start for the experienced crew.
Monday 14th keeps the early-bird theme going with another glassy morning: 4 ft from the NW at 11 seconds. Energy drops a bit to 389, but it’s still fun. The afternoons get blown out by a cross-shore, so get it while the sun’s up.
Then things get ugly. Tuesday and Wednesday (15th and 16th) are onshore, small, and weak – not worth your time. Thursday 17th has a surge to 6 ft from the NW, with strong energy at 743, but the morning has a bumpy cross-onshore wind. Too messy for a good paddle session, it’s looking more interesting for kite surfing than paddle surfing.
Now here’s the one. Saturday morning, 19th September. We’re talking 6 ft of NW groundswell, a 13-second period, and combined energy through the roof at 1242. The wind is a light offshore from the E at 3 mph. That’s clean, powerful, and barreling. It’s big enough for only the experts, but the quality is excellent.
Sunday 20th and Monday 21st keep the strong groundswell going. Monday morning the 21st is the pick of the bunch: 7 ft from the NW, a 14-second period, combined energy of 1472, and glassy offshore from the SSW. That’s absolute power, but the size means it’s advanced-only. The mornings are clean gold; the afternoons get chopped.
After that, the swell steadily fades. Tuesday 22nd still has a clean 5 ft morning, but by Wednesday 23rd it's 4 ft, and Thursday 24th is a clean but small 3 ft. From Friday 25th onwards, it’s flat – under 2 ft for days, with no real energy. A dead end to the outlook.
If you’ve got one session to chase, make it Saturday morning, 19th September, at La Graviere. That NW groundswell with offshore wind is your best shot at a proper barrel.
Rusty.
