The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window on the coast here, and while it’s not all firing, there are a couple of sessions that are going to be worth paddling out for.
The first few days are a write-off. Tuesday’s got nothing for us. Wednesday morning, September 9th, is where things start to get interesting. The swell picks up to 6ft out of the northwest, and with a light offshore breeze from the northeast, Hossegor - La Graviere is going to be offering some clean, powerful sandbar waves. The energy is solid – moderate at 537 – and that northwest swell is exactly what this spot wants. It’s a little punchy, so this is for the advanced crew, not the beginners. The water is a touch warmer than normal for this time of year, coming in at 73°.
Thursday morning, the 10th, is a glassy little gem. The swell drops to 4ft from the northwest, but with a super light SSE breeze, it’ll be smooth as a mirror. The energy is moderate (318), and the 10-second period means it’ll have some shape. This is a great window for a longboard or a funboard if you want to get some clean, easy rides.
There’s a bit of a lull with weak, small surf after that, but hold onto your board for Sunday morning, September 13th. That’s the standout. A new round of groundswell pushes in at 5ft from the northwest, but the period jumps to 13 seconds – that’s proper long-period energy. Combined with glassy conditions, it’s going to be a ripper. The combined energy is strong at 746. This is the best it’s gonna get, and it’s an advanced-level wave. The crowds can be a thing here, so get out early.
Monday morning, the 14th, is another good one. Clean offshore wind from the east, 4ft of NW swell with a 12-second period, and moderate energy at 408. Good for a decent session if you miss the weekend.
The following week gets a bit messy. The 17th of September morning has a clean-looking 5ft swell (WNW, 11 seconds), but it’s only a marginal call. The 18th and 19th of September mornings both have clean offshore winds (east) with 4ft and 4ft of NW swell, respectively. These are solid, clean options but not the same quality as the 13th. The 22nd of September brings a massive amount of energy (1301) with 6ft waves, but it’s a cross-onshore mess with 22 mph winds – that’s a kite-surfing day, not a surfing one.
After that, the 23rd of September morning looks like a sweet finish to the forecast. Glassy conditions, 4ft of long-period WNW swell, and moderate energy at 496. That’s a promising session to end on.
So, the pick of the bunch? No doubt about it: Sunday morning, September 13th at Hossegor - La Graviere. That’s the one. The long-period groundswell, the glass, the energy – it’s all there. The second best is Wednesday morning, the 9th, for the biggest swell of the run. Get on it.
Rusty.
