The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Seignosse – Les Bourdaines over the next couple of weeks. Gotta be straight with you – it’s a bit of a slow burner. The first week is mostly a write-off, so don’t be in a rush.
We start with a real flat spell. From Monday the 17th right through until the end of that week, it’s poor. Tiny swell, messy winds, and the wave energy is just pathetic – we’re talking values in the double digits like 64 to 29, barely a ripple. That combined energy stays weak (under 100) for most of that time. You’ll see a little bump on Thursday the 20th with a 3ft to 4ft NW swell and a period hitting 11 seconds, pushing the combined energy into moderate territory (193 to 377), but the onshore and cross-shore winds just chop it all up. Not worth paddling out.
Now, hold onto your boardies, because Friday the 21st of August morning is where it finally gets interesting. A clean 5ft swell from the NW, with a period of 10 seconds, and a light offshore breeze from the ENE. That’s the sweet spot. The combined wave energy jumps to a strong 451 – that’s real power for the beach/jetty setup. It’ll be a proper size, good for experts as stated. Saturday the 22nd morning hangs in there with a 4ft NW groundswell (9-second period) and an offshore easterly at 6 mph, keeping things clean. Energy is still moderate at 190. Then Sunday the 23rd morning is another gem – just 2ft, but glassy conditions with a light SE breeze. It’s small but clean as a whistle.
After that, it goes quiet again from Sunday afternoon right through the end of the month. Lots of days with poor surf and low energy, mostly below 100. There is a pulse of bigger swell on Tuesday the 25th of August (7ft WNW, period 8 seconds, energy 452) and again on Sunday the 30th of August (5ft NW, period 10 seconds, energy 496), but in both cases the wind is straight onshore or cross-onshore, turning it into a messy, blown-out affair. For the experts out there, that big 7ft day might look tempting, but the onshore wind will make it a washing machine – probably more fun for the kite crew than paddle surfers.
The standout window is without doubt Friday 21st through to Sunday 23rd of August. Friday morning is the pick: that 5ft NW swell with the light offshore wind is your best chance at a proper session. Saturday morning is a solid backup, and Sunday morning is for the clean small-wave riders. After that, the second week has a couple of bigger but wind-affected pulses that are promising but much less certain to be any good.
Stay patient, pick your moments, and I’ll see you out there.
Rusty.
