The Lowdown
Alright, grab a seat. Rusty here.
It’s a quiet stretch ahead for Biarritz - Cote des Basques (beach and reef). A classic exposed break like this usually turns it on when a solid groundswell from the west lines up, but the next 16 days are looking pretty average. There's a long patch of low-energy, messy conditions to start, where the forecast just isn't doing us any favours.
From Thursday the 30th of July right through until the morning of Saturday the 8th of August, it’s basically a write-off. We’ve got tiny lumps of swell, mostly under 2.6 ft, coming from the NW with short periods of 6 to 8 seconds. On top of that, the wind is constantly cross-on or onshore, leaving the surface chopped up and cruddy. The combined swell energy is mostly in the two-digit range – weak stuff. Total flat spell for a good paddle.
Then, on Saturday the 8th of August morning, we finally get a tiny glimmer. It’s not much, but it's the best of a bad bunch. We’re looking at a 1.6 ft swell from the WNW, with a period of 9 seconds. The wind swings light from the NNE, 3 mph, giving us a clean, glassy surface. The combined energy is still low at 48, but for a dead period, it’s something. It gets a bit of a nod as surfable waves but very ordinary conditions.
That said, the afternoon of the same day gets messy again with a stiff cross-onshore. The next morning, Sunday the 9th, sees the swell push up to 3.9 ft from the WNW, but with onshore wind and a short 8-second period, it will be a bumpy mess with a combined energy of 158 (moderate energy). The rest of the run into mid-August is more of the same – weak, short-period swell and poor wind.
So, the only window that’s even worth a look is that Saturday morning, the 8th of August. Don’t expect a classic session, but if you’re desperate for a paddle, that’s your best chance. The rest is firmly in the "leave the board at home" category.
