The Lowdown
G'day, I'm Rusty, and let's talk surf for Asturias. We're looking at a tough run of conditions here. The water is sitting at a warm 69°F, which is a touch warmer than normal for this time of year.
Right now, from Monday the 17th through to the end of the month, it's a real struggle. There's a gap of almost two weeks where the surf is just ordinary or poor. The best you'll find in this stretch is Monday morning the 17th with a 4ft swell from the ESE at 8 seconds, but it's cross-offshore wind, and the wave energy is weak (220). It's surfable, but nothing to get excited about. Wednesday morning the 19th is glassy, but the swell is tiny at 2ft. There are a few other mornings with clean conditions, like Thursday the 27th and Friday the 28th, but the swell is small and weak. The spot itself, Praia de Asturias, is a beach and reef setup that's sheltered and inconsistent, best with an easterly swell, but we're getting mostly ESE and SSE energy.
Things finally look like they might turn around heading into the new month. On Monday the 31st of August, we see a big jump in energy with a 4ft to 4ft SSE groundswell. The period is very long at 15-16 seconds, which brings real power. The combined energy is strong (864). The wind is cross-offshore and clean, which is the good news. But this is a beach and reef break, and a long-period SSE swell like that can be tricky, often breaking too straight. It's promising, but keep in mind it's a week and a half away, so it's not locked in.
The real standout, though, looks like Tuesday the 1st of September. The morning has a 3ft SSE swell, but the afternoon ramps up to 5ft from the SSE with a solid 13-second period and a strong energy reading of 852. The wind is clean and cross-offshore from the WSW, which should set up some nice lines. This is the best on offer, with good surf conditions expected. Just be aware, with 5ft of long-period groundswell, it could be a bit much for absolute beginners, but it's a proper wave for anyone with a bit of experience.
So, hang in there through the dry spell. The real hope is for the 1st of September afternoon session.

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.
