The Lowdown
Alright folks, Rusty here. Let's get into what's cookin' for our stretch of coast in Asturias. We're lookin' at a bit of a slow burn with some real promise if you can wait it out.
The early part of this run, through most of the first week, is a tough watch. There's swell around, but the wind and conditions are fighting it every step of the way, leaving us with frustratingly poor surf. The wait will be worth it for a few key windows, though.
Sunday the 9th kicks off with a messy vibe. Praia de Asturias has a weak 4ft swell out of the south, and while the mid-day water temp sits at a slightly warmer than usual 70°F, the wind is all wrong. It’s a no-go for paddling.
Monday the 10th and Tuesday the 11th are a write-off. The swell bumps up a bit but the onshore winds and rain just ruin it. The energy is there (moderate readings), but it’s all blown out. Skip it.
Wednesday the 12th is where things finally try to turn the corner. The early morning at Praia de Asturias is looking clean with glassy conditions and a clean 5ft south-southeast swell. It's not huge, but it's the first real window of opportunity. The energy sits at a moderate level. This is about as good as it gets for the first week.
Thursday and Friday keep the clean conditions rolling but the swell takes a dip. Friday the 14th morning is a nice one for the loggers – a clean 4ft south swell and light offshore winds. It's clean, it's cruisy.
Now, for the real standouts, you have to look to the second half of the run. Saturday the 15th is a solid day with clean waist-to-chest high waves, all morning and afternoon. But the true highlight, the one you’ve been waiting for, is Monday the 17th of August. Early morning glass, calm winds, and a solid 7ft swell pushing in from the east-southeast. The energy jumps right up to a strong level. This is a big, powerful groundswell. The period is short at 8 seconds, so it won't be the cleanest, lined-up wave, but with the swell size and glassy morning, Praia de Asturias will have some punchy, fun waves. Just know that at this size, it's getting a bit hefty for beginners.
After that Monday high, the surf fades fast. Tuesday the 18th drops off, and from Wednesday the 19th right through to Sunday the 23rd it’s tiny and weak, with energy readings barely breaking. Not worth paddling out for.
The very tail end of the run, on Friday the 21st of August, shows a whisper of life with a 5ft southerly swell and a clean offshore northwesterly breeze. It’s a small, weak swell. A long shot that could be a fun little session if you’re desperate.
So, if you're after the best of the best, set your alarm for Monday the 17th of August. Get on it early while it's glassy. Saturday the 15th is your next best bet for a clean all-rounder. The rest is mostly a gamble or a skunk.
Stay frothy.

Information about the Praia de Asturias Surf forecast
The above surf forecast table for Praia de Asturias provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia de Asturias can be found by selecting the local surf guide option on the grey menu.

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.
