The Lowdown
Alright, this is Rusty checkin’ in from the French coast, and we’ve got the standout spot dialed for the next couple weeks. Let’s get into it.
We’re lookin’ at Hossegor - La Graviere, a classic sandbar setup that’s exposed to the west. The water’s sittin’ at 72°F, which is a touch warmer than normal for this time of year – nice little bonus.
Right off the bat, Monday the 14th starts clean. Not huge, but a glassy 4 ft swell out of the NW with a period of 11 seconds. Combined wave energy is moderate at 389. The morning is the call with that easterly glass off. Afternoon gets a bit messy with a north wind.
Tuesday the 15th is a write-off – small and choppy. Wednesday the 16th is no good either. So we got a couple days of junk.
Then we get a serious window. Thursday the 17th morning is a beauty: 6 ft of NW swell at 11 seconds, glassy with a light southerly wind. Energy is up to 664 – get out there.
Friday the 18th is average at best.
Now, the standout hits on Saturday the 19th morning. Clean 7 ft NW groundswell, 13-second period, and an offshore easterly breeze. The energy is strong at 1325. This is a proper session for experienced surfers. Afternoon holds up but gets a bit of crosswind.
Sunday the 20th morning is another good one – 5 ft, 11 seconds, clean with offshore easterly wind. It’s a little smaller but still very surfable.
The absolute best of the forecast is Monday the 21st morning. Dead flat calm, glassy conditions. 6 ft of NW groundswell with a 14-second period. The combined energy is 1368 – that’s strong. This is a world-class window at La Graviere for the crew who know what they’re doing. The long period will make for some beautiful, powerful lines on the sandbar, but it might be a bit much for beginners.
Tuesday the 22nd and Wednesday the 23rd are marginal. Thursday the 24th morning cleans up again with a light offshorish breeze and a 4 ft NW swell at 12 seconds.
Then, another exciting one: Friday the 25th morning. Clean 5 ft swell from the WNW, but the period is 16 seconds – that’s a long, long period groundswell. Energy is strong at 1137. That’s a treat for the point and reef setups, but at Graviere it’ll still have plenty of punch and shape. Best for experienced surfers.
Saturday the 26th and Sunday the 27th are clean but smaller, with good morning windows.
The last few days of the month look pretty poor with strong onshore wind and building, messy swell. No good.
So, if you’ve got the time, the real magic is Saturday the 19th morning and Monday the 21st morning. These are the clean, powerful, groundswell sessions you wait for. Crowds are possible at La Graviere, so get in the water early.
Rusty.
