The Lowdown
Hey crew, Rusty here. Let’s talk about what’s cooking at Seignosse - Le Penon for the next couple of weeks. This is a beach and jetty spot, wide open to the west, so it needs the right conditions to line up.
We’re sitting on a bit of a dry spell right now. The first real call comes on Thursday, September 17th, and it’s marginal at best. The morning brings some waist-high swell around 6ft from the NW with an 11-second period, giving us moderate wave energy (664). That’s a long-period groundswell, and for a beach break like this, it’ll be a bit chunky and disorganized. The wind is a light cross-onshore, so it’s going to be bumpy. Not your day.
The big highlight is Saturday, September 19th. That morning is the one to circle on the calendar. We’ve got a solid 6ft swell from the NW, a long 13-second period, and strong wave energy (1223). The wind is a light cross-offshore from the SE, making for clean, smooth conditions. This is excellent for experienced surfers. The water temp is 72°, which is a touch warmer than normal for this time of year. Heads up though, with that 13-second period at a beach break, expect it to wall up and be a bit shifty. The sets will be powerful and spaced out.
Sunday, September 20th is a solid second option. The morning is clean with 5ft from the NW and an offshore breeze from the ENE. It’s smaller than Saturday, but it’ll be glassy, and this spot can get crowded, so expect some company.
Through the middle of next week, Monday the 22nd and Tuesday the 23rd of September mornings offer some clean, small waves. Both are glassy with swell around 4ft to 4ft from the NW and WNW, riding on a very long 12 to 15-second period. Again, that’s a proper groundswell, but for a beach break, the long period makes it run a bit flat and straight. Still, clean and fun on the right board.
Now for the long-range curveball: Saturday, September 26th. The morning shows a 3ft swell from the west, but with an incredibly long 20-second period. That’s a massive amount of energy for that size (908). It’ll be clean with a cross-offshore wind. For a beach break, a 20-second swell is almost too long; it’ll mostly reform and run down the beach. But if you know a bank that can handle it, it could be magic.
Sunday the 27th is also clean in the morning with 5ft from the WNW at 13 seconds and moderate energy (585). A very solid, manageable session.
To sum it up, Saturday the 19th is your standout – everything lines up. The long-range stuff on the 26th is a tempting gamble. There are quiet days in between, so pick your sessions carefully.
Rusty.
