The Lowdown

Alright, Rusty here. Let's talk about what’s shaping up for the next couple of weeks at Praia de Asturias (Asturias). Honestly, it’s a bit of a mixed bag, with plenty of flat spells and only a few moments that’ll get your heart racing. The water is sitting at about 70°, which feels a touch warmer than normal for this time of year—a nice little bonus if you’re in the water.

The swell is coming in from the ESE, but this spot is sheltered, so it takes a decent push to get it going. The optimum swell direction is from the east, so we’ve got that working for us, but the consistency here is inconsistent, so you’ve got to pick your moments.

The best chance to get wet in the first week is on Sunday 16th morning. The wind is glassy from the ENE, and we’ve got 6ft of ESE swell with a period of 8 seconds. The energy is moderate (648), so there’s enough push to make it fun. That said, the short period means it might be a bit crumbly, but with glassy conditions, it’s the standout for the early part of the outlook. This swell is a little over 5ft, so it might be a touch too much for total beginners, but for anyone with a few sessions under their belt, it’s a solid option.

After that, it’s a long, quiet stretch. From late Sunday through to the end of the first week, the swell drops away and the wind turns onshore or messy. There are a few days—like Tuesday 18th morning with 3ft and glass—but it’s too small to get excited about. You’re looking at a pretty blank run from Sunday afternoon all the way through to the following weekend.

Then we get to Saturday 22nd morning, and there’s a hint of life again. We’ve got 3ft from the SSE, glassy wind, and the energy is picking up a bit (118). It’s still ordinary, but the glassy surface makes it surfable. The real hope comes on Sunday 23rd morning—that’s a week from now. We’re looking at 3ft from the south, but with a longer period of 12 seconds (groundswell) and cross-offshore wind from the WSW. The energy jumps to 289, and the longer period means better-shaped waves. This is a point where a reef or point break would really shine, but at a beach and reef setup, you might find the waves are a bit more lined up than the short period stuff.

The next big moment is Tuesday 25th morning. We’ve got 5ft from the south, with a 13-second period (very long period groundswell), glassy wind, and the energy is pumping at 731. This is the real standout of the whole outlook. That’s a lot of power, and with glassy conditions, it’s going to be clean as a whistle. Thursday 27th morning is also worth a look: 3ft, 13-second period, glassy—another quality window at 575 energy.

After that, it fades again, with small, sloppy conditions into the end of the month.

So, to sum it up: Sunday 16th morning is your early-bird special, but the true standout is Tuesday 25th morning with that long-period groundswell and glass. Just keep in mind that at around 5ft and with that long period, it could be a bit close-outy at the beach, but if you find a bank, it’ll be magic.

Stay sharp, and I’ll catch you in the water.

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.
