The Lowdown
Alright, let's check out what's goin' on here.
To start, the water at Seignosse - Le Penon is sitting at 72°, which is a touch warmer than normal for this time of year. It's a small bonus on an otherwise slow start.
For a few days we're just watchin' and waitin'. Monday the 14th looks a bit of a tease. There’s a clean, glassy morning with some knee-to-waist high NW swell pushin’ in. It’s a gentle start, but the direction isn’t quite right for full power, and with the break bein’ inconsistent, it’s not quite worth paddlin’ out for. The next few days are a write-off really; Tuesday through to Wednesday have annoyin’ cross and onshore winds and the swell looks small and weak, so you can leave the board in the car.
Now, pay attention to Thursday the 17th. That’s the first real highlight. The morning looks like it's gonna be magic. We’ve got some glassy, clean conditions with S winds barely a whisper, and a solid NW groundswell at 6 ft. The combined energy is pumpin' at 664, so it’ll have some proper push. It’s an exposed beach/jetty setup, and the swell direction is bang on from the northwest. The crowd could be around, but with that quality, you don’t mind sharing a few.
Friday the 18th is back to average, you’re lookin at smaller, messier sets, more of a grovel than anything.
But hold onto your leash for Saturday the 19th. This is the standout for the first week. It’s an excellent morning coming up: 7 ft of clean, offshore NW groundswell with a 13-second period and combined energy of 1325. This is proper wave energy. That’s big enough to be for the experienced crew only, but the wave quality will be top-tier with that ESE wind keeping things clean. The length between sets will be longer, so you'll have time to get out the back. For the more advanced surfer, this is the session.
Sunday the 20th is still very good – clean morning again, 5 ft with 11 seconds. Not the power of Saturday but a fun, much more manageable size. Monday the 21st is another big morning: glassy flat calm winds, 6 ft with a long 14-second period, energy at 1368. That’s a very long-period groundswell which, at a beach and jetty, can sometimes wall up and close out. Worth a look, but maybe not the pick of the bunch.
The next week sees a bit of a lull. From Tuesday 22nd to Thursday 24th, the winds turn cross-on or onshore and the swell backs off. There’s a little bump of 5 ft on Friday the 25th with a very long 16-second period, combined energy strong, but it’s a pretty clean, cross-off morning. That’s a promising long-range call – a big, clean groundswell for the experienced. The wave quality forecasts are strong. For a late pick, that's your best bet further out. Saturday 26th still has clean leftover energy around 5 ft, and then the last few days of the month look to blow out in strong onshore winds, so we shut the shop after that.
If I had to pick one true standout, go for Saturday the 19th morning. If you want something a touch smaller and cleaner, Sunday the 20th. For the long-range promise, circle Friday the 25th.
