The Lowdown
Alright folks, Rusty here. Let’s take a look at what we’ve got on the menu for Seignosse - Le Penon. It’s a bit of a slow cooker this forecast, with some patience needed.
The first days are really just a write-off. We’re looking at a gap right through Thursday the 10th and Friday the 11th with nothing worth paddling out for. Thursday afternoon has a messy 4 ft NW swell, but a 12 mph cross-wind from the NNW is just tearing it up. That combined energy is weak at 271, so it’s a hard pass.
Friday the 11th morning is glassy, but the swell is a tiny 2 ft with a short period of 8 seconds, and the energy is a measly 73. You’d be floating more than surfing. Saturday the 12th is similar – small, weak, not worth the wax.
Things start to look up by Sunday the 14th. Monday morning the 14th is the first real highlight. We’ve got a clean 4 ft NW swell, with an 11-second period pushing moderate energy (396). The wind is light offshore from the E at 3 mph. That’s clean, lined-up waves for the early session. It’s not huge, but it’s your best bet for a decent paddle in the first week.
The biggest stand-out in the whole 16-day window, though, is Monday the 21st. This is the one to circle on the calendar. We’re looking at a solid 5 ft NW groundswell with a very long 13-second period. The combined energy jumps right up to 905 – that's strong, powerful stuff. The wind in the morning is light offshore from the E at 6 mph, keeping the faces clean and lined up. This will be proper, pushy waves with some serious punch. Because the period is long, it might be a little straight on the beach, but on a jetty setup like this one, you can bet it’ll handle the energy well. This one is for the experienced crew; 5 ft with that period will have some serious grunt.
Another strong runner-up is Thursday the 24th morning. Another clean 5 ft NW swell, period of 12 seconds, with light offshore wind from the E. The energy is very high at 736, so again, expert territory with a lot of water moving around.
For the week of the 17th, Wednesday the 17th morning offers a glassy 5 ft NW swell with very strong energy (559). That's a boatload of power and perfectly clean. Another good early one for the experts.
So to wrap it up: don’t even look at the water until Monday the 14th. That’s your first real window. The absolute king of the period is Monday the 21st – that’s the big, clean, powerful day. Thursday the 24th is a close second. The long-period swells will want you at the jetty end to find the best shape.
Keep your wetsuit handy, a bit of a wait but the payoff looks decent. The water is 73°F, which feels a touch warmer than normal for this time of year – nice.
Rusty.
