The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks at Seignosse - Les Bourdaines. It’s a bit of a mixed bag to start, but there are some days that are gonna get the blood pumping, trust me.
Right off the bat, it feels weird to say we’re starting with a Thursday morning session on the 10th that’s pretty much a write-off. The water here is sitting at a balmy 73°F, which is much warmer than normal for this time of year—silver linings, right? But the swell is just not there for a proper session. You have to wait until Sunday the 13th. That morning is where it finally gets interesting. We’ve got a clean, glassy start with a 4ft NW groundswell rolling in with a long period of 13 seconds. The combined energy is pumping at a solid 501, which is moderate wave energy. With those light offshore winds from the West, it’s gonna be clean and lined up. This is your first real standout.
Monday the 14th keeps the good vibes rolling with another glassy morning, 5ft of NW swell. That’s a solid head-high plus, and there’s plenty of energy in the water (431). Conditions are looking really good for a dawn patrol.
Now, we hit a dry spell. From Tuesday the 15th through to Thursday the 17th, the wind is just not playing ball. It’s messy and cross-onshore, chopping up what would otherwise be a decent swell. It’s not worth paddling out for the frustration.
We get a little reprieve on Friday the 18th morning. It’s small at 3ft, but it’s glassy with an offshore breeze from the SE. That’s a clean little wave for a longboard or a fish. Then on Saturday the 19th morning, we get a proper offshore from the East, with a clean 4ft NW swell. That’s a good session.
Here’s the big one, though. Mark your calendar for Sunday the 20th. The morning is looking absolutely wild. We’ve got a 6ft swell from the WNW, but the period is a super short 6 seconds—that’s windswell, and it’s going to be a bit lumpy and closey. However, the energy is low-moderate (279), and it’s dead calm, glassy. It’s going to be tricky but fun. But the real gee-up is Monday the 21st. That morning is for experts only. We’re seeing a 10ft NW swell that jumps to 12ft in the afternoon. The combined energy is off the charts—2400 and 3619 respectively. That is very strong wave energy. It’s too big for this break for a paddle session; if you’re a charger on a jet ski, maybe, but honestly, this looks more interesting for a big wave tow or kite setup than a standard paddle. The onshore wind is going to make it a beast.
The week after that gets a bit more manageable but remains solid. Tuesday the 22nd and Wednesday the 23rd see 7ft swells, but the wind keeps it a bit bumpy. Then, the real treat for the second week is Thursday the 24th morning. Get on it. We’ve got a 3ft glassy wave with a period of 17 seconds from the WNW. That is a super long groundswell. The energy is strong (800), and those long lines will wrap in beautifully. This is a point-break dream scenario—clean, long walls. It’s not massive, but the quality is going to be top-tier. That’s your second standout.
For the rest of the run into the 25th, it gets a bit chunky and onshore again, with size but not quality. Keep an eye on the forecasts; it can change.
Rusty out.
