The Lowdown
Alright, let’s talk waves for Asturias.
To be straight with you, the next week and a half is going to test your patience. We’ve got a long stretch of small, messy surf and onshore junk. Not much worth paddling out for until we see a real pulse of energy.
The first glimmer of anything with a bit of push shows up on Wednesday, September 2nd. The swell builds to 6ft, but it’s coming in from the south with a short 14-second period, and that’s onshore wind. That’s not a surf forecast, that’s a washing machine. The energy reading jumps to 1350, which is strong, but it’s all over the place.
We get a little reprieve on Thursday the 3rd with a smaller 4ft SSE pulse, and it’s dead glassy in the morning. That’s your window for a few clean shoulders at Praia de Asturias, but it’s still not firing. You’ll be fighting for scraps.
Honestly, the standout of the whole window looks like Friday, September 11th. The swell direction swings around to the south with a 5ft wave and a 10-second period. The wind is cross-offshore, keeping it clean. Energy is solid at 622. That’s the morning to make the call.
Then Saturday the 12th has a bigger 6ft ESE swell, but with a short 7-second period that won’t have much punch. It’s cross-offshore though, so it might offer a few fun ones if you’re keen on a grovel.
Praia de Asturias is your spot. It’s a beach and reef combo, sheltered, and it can handle these swells. It’s rated for beginners, but it’s inconsistent, so don’t expect perfection. With the bigger swells, the 6ft stuff is okay for most, but that south energy can get a bit unruly. And the water temp? It’s about average for this time of year.
The gap between the end of this week and that September 11th window feels like forever, but that’s the price we pay for living here. It tends not to stay flat for long. The forecasts will change, and we’ll be ready.
Keep an eye on that Friday the 11th. That’s the one.
