The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Seignosse - Le Penon over the next couple of weeks.
Right off the bat, let's talk about the water. It's sitting at a balmy 74°F right now, which is a good 4°F warmer than what we'd normally expect for early September. That's a notable little anomaly, feels like summer's hanging on.
The outlook starts off pretty flat. Friday morning is glassy, with a tiny 2ft WNW swell, but the energy is weak (80). It's surfable, but you'd be scratching for anything decent. The real action doesn't kick in until Saturday morning. That's the first standout of the period. We've got a clean 3ft swell from the WNW with a light offshore breeze from the East. The energy is moderate (236), and the conditions are looking clean. It's a small window, but that's the pick of the first few days.
Saturday afternoon sees a jump in size to 5ft from the NW with a period of 13 seconds, but the wind swings North and gets a bit stiff, making it a cross-off. The energy is strong (680), but the wind is a bit of a spoiler. Sunday is a write-off with onshore winds and messy conditions.
The next real glimmer of hope comes on Wednesday, the 9th of September. The morning session offers a 4ft NW swell with a light cross-off breeze from the North, and the energy is moderate (351). It's clean, but nothing to write home about. Then we get a real treat on Thursday, the 10th of September. The morning is glassy with a 4ft NW swell, a period of 10 seconds, and moderate energy (241). That's a great combo for a longboard or a funboard. The wind is dead calm, so the surface will be like a mirror.
After that, the forecast gets a bit scrappy. There's a small, glassy session on the morning of Saturday the 12th with a tiny 3ft swell, but the energy is weak (86). The next real chance to get a decent wave doesn't come until Monday, the 14th of September. Another glassy morning, this time with a 4ft NW swell and a 10-second period, offering moderate energy (265). It's clean, but it's a small window.
The second week is a bit of a mixed bag. There's a small window on the morning of the 18th of September with a 3ft WNW swell and a light offshore breeze from the East, but the energy is weak (157). The conditions are clean, but don't expect any power. For the rest of the second week, it's mostly onshore or cross-shore wind with small, weak swells. It's not looking great for the latter half of the window.
So, if you're looking for the absolute best on offer, your two standout windows are Saturday morning, the 5th of September, with that clean 3ft offshore swell, and Thursday morning, the 10th of September, with the glassy conditions and that 4ft NW swell.
Remember, this is a beach/jetty setup, so it's exposed and can get a bit inconsistent. The Saturday morning swell is a bit longer period (13 seconds), which can sometimes make a beach break a bit fat, but with the offshore wind, it should be peeling nicely. The Thursday morning swell is more of a standard groundswell and will be perfect for the sandbanks.
Keep your eyes on the forecasts, but right now, the first week is where the magic is.
Rusty.
