The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's coming our way for the next couple of weeks.
Alright, we’ve got a mixed bag coming up. Nothing massive or perfect straight away, but there are a couple of windows that’ll get the stoke up. We’re looking at Seignosse - Les Bourdaines, a beach and jetty setup that’s expert-only. The water’s sitting at 73°, which is much warmer than normal for this time of year – a solid 4° above average, so don’t expect the usual autumn chill just yet.
We kick off Monday the 7th with a bit of a slow start, but Tuesday the 8th is flat with onshore winds – not worth paddling out. Wednesday the 9th morning is where we first see something interesting. A clean 6ft swell from the NW with a 9-second period, and a light offshore breeze from the NNE. The combined energy is moderate at 492, so there’s some grunt there, but it’s short-period, so it’ll be a bit crumbly and fat. Not the day’s highlight, but a start. That afternoon the wind swings cross-on and it gets choppy.
Now, Thursday the 10th – this is a real standout. We’ve got a 4ft NW groundswell with a 10-second period, but the magic is the completely glassy conditions, zero wind. The water will be like a mirror. Combined energy is a moderate 351. That’s going to be clean, lined-up, and proper fun for the experts at this break. Crowds are sometimes a factor here, so get out early if you can.
Friday the 11th is small and glassy again in the morning, but only a 2ft wave with weak energy (76) – more of a longboard session if anything. Then we hit a big gap. From Saturday the 12th all the way through to Sunday the 13th, it’s all onshore and messy or tiny. Monday the 14th morning looks glassy again with a nice 5ft NW groundswell, period 12 seconds, and very good conditions – combined energy is a solid 580. That’s a proper swell, but the wind goes cross-shore in the afternoon so the window is tight.
We get another big lull Tuesday the 15th and Wednesday the 16th. Then things really fire up in size, but with awful winds. Thursday the 17th has 8ft NW swell but all onshore. Friday the 18th pushes even bigger – 8ft NW, combined energy hitting 1274, which is strong – but again, onshore wind. This is shaping up more for the kitesurfers, not for paddle surfing.
Finally, the best of the later period is Saturday the 19th. We’ve got a clean 5ft NW swell with a 10-second period that morning, but the big difference is the offshore wind from the east. Combined energy is a moderate 384, and the conditions will be clean and lined. That’s your second standout, but it’s a week and a half away, so keep an eye on it – long-range certainty is always a bit less solid.
So, the two windows to circle are Thursday the 10th with the glassy perfection, and Saturday the 19th with the offshore clean-up. Everything else is either too small, too windy, or too big and messy.
Rusty.
