The Lowdown
Hey crew, Rusty again. Let's break down the same forecast for Biarritz - Cote des Basques, but in feet and degrees.
Right off the bat, this is a tale of patience. The first week is a write-off. We're not seeing anything worthwhile until around Tuesday, July 21st, and even then it's barely a ripple. You'll be sitting on the sand for a good stretch.
On Tuesday morning the 21st, a small pulse finally shows – about 3ft from the NNW, but with a short period of only 6 seconds. The wave energy is weak (11 on the combined scale). The only saving grace is the wind going glassy. It's surfable, but you won't be bragging about it.
The rest of the week is mostly forgettable. We get some size on Sunday the 26th and Monday the 27th, with waves around 5ft to 6ft, but the wind is all wrong – onshore and cross-onshore – turning everything into a lumpy mess. The water temp is about normal for the season, so no worries there.
Now, for the pick of the litter: Wednesday morning, July 29th. This is the day. We're looking at a consistent 5ft of swell from the NW, with a period stretching to 11 seconds. That's real groundswell energy (the combined energy is 595, a hefty number). But the main event is the wind – dead calm, glassy conditions. For a spot like Cote des Basques, a mix of beach and reef, that means silky smooth waves. With the wind coming from the East, it's offshore, too. It won't be a giant day, but the quality will be unmatched. It's a great window for all levels.
After that peak, it's a slow downhill slide back to small, windblown dribble into the beginning of August. Your window is the 29th. Don't sleep on it. This is Rusty, out.
