The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
It’s a bit of a slow start for Biarritz - Cote des Basques. The first week is mostly a write-off, with a lot of poor conditions and choppy, onshore wind messing up the waves. Honestly, there’s nothing worth paddling out for until the 22nd of July, and even then it’s just small, weak surf with a combined wave energy of only 52 (moderate energy). The real story is the wait for a proper clean-up.
We get a few small windows of opportunity. The morning of the 23rd of July looks promising with glassy conditions and a tiny 3ft swell from the NNW, but it’s a fleeting moment. The morning of the 28th of July is a decent shout with a clean 4ft swell from the NW and a light offshore breeze, making for some tidy lines. The morning of the 29th of July is similar, with a clean 4ft NW swell and offshore wind, feeling much better.
The standout of the whole period, however, is the morning of the 2nd of August. This is a big one for the experts. A massive 13ft groundswell from the NW is rolling in, with a very long period of 10 seconds and a combined wave energy reading of 3172 (very strong wave energy). The wind is dead calm, glassy as can be. But listen, this is a beach-and-reef break, and at this size, it's going to be a serious, heavy beast. It’s only for experienced surfers who know what they’re doing. The water temperature is a very unusual 77°F, which is much warmer than normal for this time of year.
After that, things settle back down. The 3rd of August morning brings a clean, glassy 4ft NW swell, which is a nice, manageable option for the average surfer. The window then closes again with small, onshore slop for the rest of the forecast.
So, to sum it up: the first week is a struggle. The 2nd of August is the big, dangerous highlight for experts only. For the rest of us, the mornings of the 28th and 29th of July, and the 3rd of August, are your best bets for a clean, fun session.
