The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Seignosse - Le Penon. I’ll be straight with you – the next couple of weeks are a mixed bag, with a few moments of magic if you’re patient.
We start off a bit rough. Wednesday morning has some knee-to-waist high swell at 6ft, but it’s coming from the NW with a short 9-second period and a cross-shore wind, so it’s going to be a bit of a messy, choppy affair. The wave energy is moderate. Honestly, not worth paddling out for. The afternoon is even worse.
The first real chance of something decent comes on Thursday the 10th. The morning shows a clean 4ft NW swell, with a sweet 10-second period and a light offshore wind. The wave energy is moderate. That’s a proper window for a session. The afternoon gets a bit bumpy again.
The weekend looks small and weak. Friday and Saturday mornings have tiny glassy waves, 2ft to 3ft, but the energy is very low. It’s surfable for a longboard if you’re desperate, but not much fun.
Now, here’s the standout. Sunday the 13th morning is where it gets interesting. We’ve got a 4ft NW swell with a long 13-second period, which is proper groundswell energy. The wind is glassy, and the combined energy is moderate. This is the best-looking session in the first week. Le Penon is a beach/jetty setup, so that long period might make it a bit straight, but the glassy conditions should iron that out. The afternoon is okay but gets cross-shore.
Monday the 14th morning is also a beauty. Clean, glassy conditions with a 4ft NW swell, 12-second period, and moderate energy. That’s a solid follow-up session.
After that, the surf drops off quickly. There’s a long gap of poor conditions from Tuesday the 15th right through to Friday the 18th. Small, weak waves and onshore winds. Not worth your time.
We get a bit of a pulse again on Saturday the 19th morning. A 4ft NW swell with a short 8-second period, but it’s glassy. The energy is moderate. It’s a fun little wave, but that short period means it won’t have much punch.
The next real highlight is Sunday the 20th morning. Glassy, clean conditions with a 4ft NW swell, 10-second period, and moderate energy. That’s a nice, clean surfable day.
After that, it’s a long, flat run. From Monday the 21st until Wednesday the 23rd, the swell is tiny and the wind is onshore. The wave energy is very low. The morning of the 24th of September shows a glimmer of hope: a 4ft WNW swell with a long 14-second period and offshore wind, giving moderate energy. That’s a promising one, but it’s a long way off.
The water temp is about average for the time of year, nothing wild to report.
So, to sum it up: the best windows are Sunday the 13th morning and Monday the 14th morning. Get out there for those. The 20th of September is a solid backup. The rest is small or choppy. Stay patient.
