The Lowdown
Alright folks, it’s Rusty here, and I’ve got to be straight with you – the next 16 days are lookin’ pretty lean for a paddle. We’ve only got one spot in the picture, and frankly, it’s a tough one to get excited about for most of the window.
Right now, from Wednesday the 16th all the way through to the end of the month, Greve de Lacq is really struggling. The swell is small and wobbly, and the wind just won’t play ball. You’re lookin’ at a lot of choppy, cross-shore junk with the odd clean-ish window, but nothing that’s gonna get the heart racin’. The wave energy is moderate at times – hitting around 645 (combined energy) on Thursday morning the 17th – but a 25 mph cross-off wind will keep things blown out. The swell direction is mostly west and WNW, around 5 ft to 6 ft for a day or two, but the wind’s just too strong.
There’s a bit of a tease on Friday the 18th with a 5 ft to 4 ft swell from the WNW and a long period of 13 seconds in the afternoon – that’s real groundswell potential for a point or reef, but at a beach setup ropes are gonna be straight and the cross-shore wind will still mess with the face. Not worth a dedicated trip unless you’re desperate for a splash.
We hit a proper lull from Sunday the 21st right through to Saturday the 26th – days with swell barely pushing 3 ft, and sometimes as little as 1.0 ft. Energy drops to a pathetic 20 (combined energy) on the 26th. That’s a dead zone.
If you’re lookin’ for the standout, it’s gotta be Monday the 28th of September. The swell bumps up to 4 ft from the WNW with a very long period of 14 seconds, and combined energy hits a strong 850. That’s the biggest, most powerful pulse of the run. But here’s the rub – the wind is cross-onshore and choppy, and at 4 ft with that long period, a beach break like this could be fat and hard to handle. Still, if you’re an experienced local who knows the banks, that morning might give you a few clean-ish walls. But keep the crowds in mind – they can be around sometimes at this break.
The last day of the run, Wednesday the 30th of September, shows 7 ft of W swell. That’s the biggest height, but wind is cross-on and lumpy. Energy is a solid 755 (combined energy), and cross-on wind at 7 ft will be a choppy mess. Not one for the beginners – that’s expert territory in these onshore conditions.
In short, it’s a long, quiet stretch with maybe one or two sessions worth a look if you’re really keen. The lack of decent swell and clean windows means the kite crew might get more out of these onshore days than us paddle surfers.
Rusty.
