The Lowdown
Alright, Rusty here again. The 16-day window starts slow, but there’s a couple of mornings that get the heart rate up. Water temp is a balmy 74° – that’s a good 4° warmer than usual for early September, so ditch the wetsuit if you can.
Right out of the gate, Friday the 4th is a wash – glassy but barely a ripple at 2 ft with weak energy (57). Not worth the walk. The first real nod is Saturday morning, September 5th. We’ve got a clean 3 ft from the NW, energy up to 229 (moderate), and a light offshore breeze from the E. That’ll put some gloss on *Biarritz - Cote des Basques* (beach and reef). The period is 9 seconds, so nothing hectic, just fun little walls. Perfect for a beginner or a log.
The absolute standout is a full week out, on Sunday morning, September 13th. Swell pushes to 5 ft from the NW with a 12-second period (energy 528 – strong). That’s proper groundswell with some grunt. And the wind? Offshore from the E at 9 mph. That’s the recipe for clean, lined-up waves. The break is fairly consistent, which isn’t always the case here, and with that swell direction matching the optimum, it should hold shape. Crowds will be likely – it’s a popular spot – but early birds will feast. This one is solidly intermediate territory.
Then we get Wednesday morning, September 16th – the second highlight. It’s glassy – totally dead wind – with 5 ft from the NW, period 10 seconds, and energy at 562. That’s the biggest clean swell of the whole run. It’s pushing into expert territory for size, but with those glassy conditions, the sets will be gorgeous. A bit too much for the groms, though.
In between, there’s a lot of choppy afternoons and onshore slop. The first week has Sunday the 6th through Tuesday the 8th looking messy with cross-onshore winds. Thursday morning the 10th offers a glassy 4 ft, but the energy is only moderate (284) – surfable, but not a champion. The second week has Tuesday the 15th and Thursday the 17th with clean starts, but the swell dips under 3 ft. The final days on the 18th and 19th are tiny 3 ft again – glassy but skinny.
Bottom line: for clean, punchy waves, set your alarm for the mornings of the 13th and 16th. Those are your gems.
Rusty.
