The Lowdown
Alright, grab a coffee and listen up. It's Rusty here, and I've been staring at the charts for Asturias. To be honest, it’s a bit of a slow start and a mixed bag overall.
We've got Praia de Asturias as the go-to, and honestly, the next few days are flat and forgettable. From Saturday the 29th of August right through to Tuesday the 1st of September, it's mostly tiny, weak dribble. The swell energy is basically non-existent, reading as low as 38 to 95, so don't even bother waxing up. It’s a beach and reef setup that’s well sheltered, and the water temp is about average for the time of year. Not much to write home about.
Things get a bit more interesting on Wednesday the 2nd of September. A big, muscular southerly swell rolls in, hitting about 10 ft on Wednesday morning with a solid 13-second period between sets. The combined energy jumps to 5210, which is serious power. However, it’s a cross-onshore wind from the south at 9 mph, so it’s going to be choppy and a bit of a mess. This is big, powerful stuff – definitely only for experts, and maybe more of a spectacle than a good surf session. It settles to 7 ft in the afternoon with a cross-shore wind, so still messy. Not the stand-out we want, honestly.
The real highlight, the one to circle on your calendar, is Friday the 11th of September. The morning is looking like the best on offer for the whole run. We’ve got a clean, 3 ft swell from the SSE with a lovely long period of 14 seconds. That’s proper groundswell energy (447 combined), and with a cross-offshore wind from the WSW at 9 mph, it will be super clean. That’s a 3 ft set with smooth, well-shaped lines. It'll be a bit inconsistent given the long period, but that paddling out will be a breeze. It’s the best you’re going to get, just be warned the crowds are a possibility there.
A few other days, like the morning of Thursday 3rd, offer clean 5 ft but with very ordinary conditions. And the morning of the 8th September has a solid 5 ft with a clean cross-offshore, but again the energy is a bit messy. Stick to the 11th.
So, take it easy early on, get some other stuff done, and aim for that Friday morning. Don't hold your breath on the rest.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia de Asturias may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
