The Lowdown

Alright, surfers, Rusty here with the long-range look for Asturias. I’m telling you straight, this is a rough patch. We’ve got a good two weeks of looking at the charts and finding very little to get excited about. The first real chance of anything surfable doesn't show up until Tuesday the 8th of September, and even then, it's a struggle. The best I can say is that there are a couple of windows of clean, small waves, but don't expect any heroics.

The wait is on until Tuesday morning, the 8th. We finally get a break from the rain with some clear skies and glassy conditions at Praia de Asturias. The swell is small, only about 3 ft from the south with a moderate 11-second period. The combined energy is weak (212), so it's more of a longboard or foiling session. The wind is completely off the water – glassy, which is a major positive. The crowds are sometimes an issue here, so you might have a few others with the same idea. The water temp is sitting at 71°, which is a touch warmer than normal for this time of year, so a spring suit will be fine.

Tuesday afternoon stays clean with a light cross-offshore breeze, but the swell drops a notch. The pattern continues Wednesday and Thursday mornings with more glassy conditions and tiny, knee-high waves from the southeast. The period is short on Wednesday (7 seconds), but it stretches out to a nice 12 seconds by Thursday morning. Still, the energy is low (196). It’s ordinary, but at least it’s clean enough for a paddle.

After that, things go a bit flat and messy over the weekend of the 12th and 13th. The swell drops to barely a ripple on the Saturday, with only 1 ft and energy readings in the 30s. Not worth getting wet for. Sunday the 13th sees a bump in size to 3 ft, but the wind is up and the quality is poor.

Looking further out to Saturday the 19th of September, there’s a flash of something bigger in the data. The swell is forecast to be 4 ft from the south-southeast, but with a very long 17-second period. That’s a lot of energy, reading at 818! This is a proper groundswell, but the wind is a light cross-onshore which will put a bit of texture on it. This kind of long-period swell can be tricky at a beach-and-reef setup like this, often breaking too straight. It’s a promising long-range signal, but don’t lock it in yet. The next day, Sunday the 20th, has a similar story with a 3 ft, 15-second south swell, but the onshore wind is stronger. It looks more like a kiteboarding setup than a clean paddle session for those last two days.

Honestly, for the next two weeks, the best windows are those small, glassy mornings on Tuesday the 8th, Wednesday the 9th, and Thursday the 10th. They are the only standouts for a clean, if tiny, surf. The rest is a write-off.

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.
