Seignosse - Le Penon Surf Forecast and Surf Report

Right then, let’s have a proper look at the forecast for Seignosse - Le Penon.

The first recommendation kicks off on Saturday the 12th of September, but honestly, it’s nothing to write home about. We’re looking at a weak 3ft swell from the WNW, and while the morning is glassy with 5 km/h easterly wind, the energy is weak. The water’s a touch warmer than normal at 72°, which is a nice detail, but the surf itself is very ordinary. By the afternoon, the wind swings NNW and picks up to 20 km/h, making a mess of things, so don’t bother.

Now, Sunday the 13th is where things get interesting. We’ve got a proper groundswell building. The morning is a standout: 4ft from the NW with a long period of 13 seconds, pushing the combined energy right up to 501 (moderate wave energy), and it’s dead calm – glassy conditions. This is the best on offer early on. That long period will make for clean, well-shaped waves at the beach/jetty setup, with plenty of power. The afternoon holds similar size at 5ft but a cross-shore wind creeps in, so the morning is the clear winner.

Monday the 14th morning is still clean, with offshore wind from the east at 5 km/h and a 4ft NW swell. The energy is down a touch, but it’s still a good window before the wind turns cross-shore in the afternoon.

We hit a rough patch from Tuesday the 15th through to Wednesday the 16th. The swell builds to 5ft, but the wind is onshore or cross-onshore and gusty, making for poor, choppy conditions. Not worth a paddle.

Thursday the 17th morning has a 5ft swell from the NW with a solid 12-second period and good energy, but light rain and cross-shore winds keep it marginal. Tough call.

Friday the 18th morning is another surprise: a return to glassy conditions with 0 km/h wind from the SSW and a 4ft NW swell. It’s not huge, but it’ll be clean and fun.

The real highlight this week is Saturday the 19th morning. That’s the one to circle. We’ve got 6ft from the NW at a long 13 seconds, with glassy conditions and strong wave energy. The water is still that touch warmer, and the waves will be powerful and clean for anyone with a bit of experience. Beginners might find 6ft a bit much, but for everyone else, this is the session. Glassy and punchy.

After that, the swell eases a little through the second week. Sunday the 20th morning has a clean 4ft swell, and Monday the 21st shows a big spike in energy for the afternoon, but that’s with a cross-onshore wind making it messy. The size jumps to 6ft, but the wind isn’t on your side.

The rest of the week into the 27th sees mostly marginal conditions with smaller swells, often cross-onshore or onshore winds, and dropping wave energy. The mornings on the 24th and 25th of September offer some clean, smaller options with cross-offshore winds and decent 4ft swell from the NW, but nothing that screams epic. The period on the 24th is a very long 14 seconds, which will produce some nicely lined-up waves for the point/reef sections, but at 2ft it’s more of a longboard glide than a performance wave.

So, overall: the absolute standouts are Sunday the 13th morning for the glassy start of the groundswell, and Saturday the 19th morning for the best combination of size, power, and glass. Get out there for those windows.
