The Lowdown
Alright folks, Rusty here, and we're looking at a pretty grim couple of weeks for the Asturias coast. Honestly, it's a long stretch of small, junky waves with very few moments where the stars align. The first real chance at anything rideable doesn't pop up until Saturday the 22nd, and even that's a cautious call.
The water's about 69°, which is a touch warmer than normal for this time of year, so you won't freeze your toes off.
The one window worth paddling out for is Praia de Asturias on Saturday morning, the 22nd. We've got a 4ft south swell with an 11-second period. That's a proper groundswell, so you'll get some shape, but the lulls between sets will be longer. The energy is moderate, coming in at 331. The real selling point is the glassy, dead-calm wind – that's the cleanest we'll see for days. The catch is it's an inconsistent spot, and it's a sheltered beach and reef setup that *sometimes* gets crowded. On a Saturday with the only clean window, you better believe it'll be busy.
After that, it's back to the struggle. Monday the 24th brings a bigger pulse – 5ft from the SSE with a very long 14-second period and strong energy (1045). But the wind is onshore from the SE, and it's labeled marginal. That's expert territory and not a beginner's wave. Then Tuesday the 25th has 5ft but gets hammered by 15 mph onshore winds, making it a choppy mess.
The rest of the run through September 2nd is a parade of tiny waves, onshore breezes, and cross-chop. You might find a knee-high ripple on a glassy Wednesday morning the 26th, but don't hold your breath. There's a bit of cross-offshore wind on the 31st with 4ft of short-period swell, but it's not clean enough to get excited about.
In short, the only game in town is a clean but inconsistent session at Praia de Asturias on Saturday morning the 22nd. After that, it's a waiting game for something better to show up.

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.
