The Lowdown
Alright, folks, Rusty here. Let's have a look at what's cookin' out there.
Well, to be honest, it’s a slow start. We’ve got a bit of a dry spell to kick things off, but the back half of this 16-day window is where it gets real interesting for those who can wait.
For the first couple of days, Monday and Tuesday, the surf is pretty flat and weak. The water’s warm though – a solid 77°, which is much warmer than usual for this time of year. That’s a nice touch if you’re just hanging out. We’re looking at tiny 1ft to 2ft swell with hardly any energy behind it. Not worth paddling out for. The wind is light, and on Tuesday morning it goes glassy, but there’s just nothing to ride.
The real turning point comes Thursday morning, the 20th of August. Finally, some life! Playa de Gaztetape sees a nice jump to a 4ft groundswell from the NW, with a sweet 11-second period. The energy is moderate, and we get glassy conditions. That’s the first session to look at. The swell builds through Friday morning the 21st, hitting 5ft from the NW with a 10-second period and strong energy, and again, glassy winds. That’s the best of the first week right there.
After that, things fade again over the weekend and into the start of the following week, with smaller NW swell and messy cross-onshore winds.
Now, for the true standouts. Keep your eyes on Friday the 28th of August. Thursday morning the 28th sees a solid 6ft NW groundswell with a 12-second period – that's long-period groundswell energy. The combined energy is pumping, and it’s glassy. This is the one. It’ll be a bit bigger than the previous week, offering good shape. Just a heads up, that long period can make beach breaks wall up, but Playa de Gaztetape handles it well.
Then, the absolute highlight if you’re an experienced surfer: Tuesday morning, the 1st of September. This is the big one. We’re looking at an 8ft NW groundswell with a 14-second period. That’s very long-period groundswell. The energy is massive. It’s glassy. This is expert territory for sure, but the conditions are forecast to be excellent. The swell direction matches the break’s optimum. This is the session you want. Get ready for that.
So, the long-range call on that 1st of September swell is the standout, though it’s less certain this far out. The 28th of August is a safer, still very solid bet. The first week is mostly a wait-and-see, but the payoff at the end looks brilliant.
Rusty, signing off.
