The Lowdown
Alright, let’s switch it over for you sandal-wearing, foot-based measurement types.
Right off the bat, we’re looking at a slow start. The first few days up to Friday the 21st are mostly poor with onshore cross-winds chopping up anything that rolls in. Thursday morning the 20th sees 4ft swell from the NW with an 11-second period, but that cross-onshore wind just ruins it. The combined energy (297) is moderate, but not worth paddling out for.
Now, Saturday the 22nd is where things start to look up. Seignosse - Le Penon should have some clean lines in the morning. We’re looking at a 4ft NW swell, a 9-second period, and light cross-offshore winds from the SE. The combined energy sits at (211) – moderate. It’s a beach/jetty setup, so it can handle a bit of push, and with the wind playing nice it should offer some fun, clean waves. A good one for a range of abilities, though the swell isn't huge.
Sunday the 23rd drops off quickly. The swell drops to 3ft with a short 7-second period, and while the wind is offshore, the energy is weak (92). It’s surfable but ordinary.
There’s then a real quiet patch from Monday the 24th right through to Wednesday the 27th with tiny swell and mostly onshore or cross-onshore wind. Thursday the 27th morning does show a bump of 7ft from the WNW, but it’s a short 7-second period and onshore wind, making it a messy, lumpy affair. Not one for the beginners.
Friday the 28th brings back a cleaner window. Morning sees a nice 4ft NW swell with a 10-second period and cross-offshore winds from the ESE. The energy reads (273) and the conditions look clean. This is another good option for intermediate surfers – the swell direction matches the optimum west, giving the break a nice shape.
After that, the end of the run on Sunday the 30th and Monday the 31st offer similar clean morning windows with 4 to 4ft NW swells and light offshore to cross-offshore breezes. The real standout is Wednesday morning, September 2nd. We get 4ft from the WNW, a 10-second period, and glassy conditions. The combined energy is strong at (439). That, right there, looks like the best session of the whole outlook – clean, decent power, and no wind to mess it up. If you can wait, that’s the one to circle.
Water temp is running about average for the time of year here, so no drama there.
To sum it up: The first week is mostly a write-off. The standout windows are Saturday the 22nd, Friday the 28th, and the absolute pick is Wednesday, September 2nd with glassy 4ft WNW swell. That’s the morning to be in the water.
