The Lowdown
Hey everyone, Rusty here with the Imperial version. Let’s look at what’s coming up at Hossegor’s famous beach, La Graviere. We’ve got a real mixed bag of a 16-day window with some proper standouts but plenty of flatter days and onshore crud. The water temp is sitting at 74°F right at the start, and that’s a full 4°F warmer than normal for this time of year – feels more like a late summer hangover.
We kick off Saturday the 5th morning. Small but clean with an easterly light breeze. Swell is 3ft from the WNW at 9 seconds, not much grunt, but with glassy conditions it’ll be fun on a longboard. Combined wave energy is low at 236. Saturday afternoon the wind swings north and picks up, and the swell bumps to 5ft with longer 13-second periods, but the moderate cross-offshore wind keeps it fairly clean for the experienced crew.
Sunday the 6th is not our friend. WNW onshore wind messes up the 5ft NW swell early, and it gets worse in the afternoon with cross-onshore chop. Monday the 7th is flatter and lumpy.
Wednesday morning the 9th is a standout. Glassy conditions, a light ESE breeze, and 4ft swell from the NW at 9 seconds. Moderate wave energy (378) and totally clean. This is the morning to get out there.
Thursday the 10th morning is another gem. Completely calm, glassy, and 4ft of NW swell with 11-second period. Energy at 326. That’s a proper clean session.
After that, surf drops off. Mixed conditions dominate with poor wind. There’s a brief window on Saturday the 12th morning with glassy conditions and 3ft, but weak energy at 135 – ordinary.
Sunday the 13th morning is the real highlight. Flat calm, glassy as a mirror. Swell is 4ft from the NW at 12 seconds, moderate energy of 435. Long period groundswell– this is pure autumn grade.
Monday the 14th morning also has promise – offshore SE wind, 4ft at 10 seconds, clean lines.
The second week is mostly small and weak. A little blip on Friday the 18th afternoon with glassy conditions and 3ft NW swell. Saturday the 19th afternoon has some clean 3ft surf. But after the 14th, it’s mostly waiting around, with about five or six days of no real recommendations.
Bottom line: The clear winners are the mornings of Wednesday 9th, Thursday 10th, and especially Sunday 13th. That Sunday morning is the one to circle – glassy, long-period, classic La Graviere.
Rusty.
