The Lowdown
Alright, grab a coffee and settle in. It’s Rusty here, taking a good hard look at what this next stretch has in store for us at Praia de Asturias.
Honestly, we’ve got a bit of a flat spell on our hands for the start. There is surfable energy in the water from the jump, but it’s nothing to write home about. The first recommendation comes in on Friday the 4th of September with some pretty average waves. The swell is coming from the SSE at 3ft, with a period of 11 seconds. It’s weak energy (180) and the wind is glassy in the morning. The water temp feels pretty average for this time of year, so no need for a thick steamer yet. It’s surfable, but I wouldn’t rush down for it. That afternoon the wind swings SW and it turns a bit lumpy.
Saturday the 5th is a write-off. Tiny, poor conditions. You’ll be mostly scratching your head.
Sunday the 6th gets a bump in size, up to 5ft from the S, but the period drops to a super short 8 seconds and the wind is cross-onshore and choppy. That’s not paddling-friendly. The energy is moderate (271) but the quality is gone. This setup looks more interesting for kite surfing than paddle surfing, honestly.
Monday the 7th is similar – onshore winds, messy, 5ft to 6ft. A bit of a rain parade too.
Finally, we get a window on Tuesday morning the 8th. Glassy conditions early with a 5ft swell from the ESE. The wind is glassy, so it’ll look clean, but the period is short at 7 seconds, so expect a bit of a bumpy, weak ride. The energy is moderate (363). It’s not a standout, but it’s the first cleanish day with some size. That afternoon, it’s back to cross-shore junk.
Wednesday the 9th and Thursday the 10th are small and unexciting. Glassy mornings on both days with tiny, weak swell (under 3ft). You could get wet, but you won't be stoked.
Friday the 11th and Saturday the 12th are nothing to talk about. Small and weak.
We hit a real dead zone from Sunday the 13th all the way through... not much. A few days of onshore winds and tiny waves.
The end of the run gets a little more interesting but still not epic. On Wednesday the 16th of September, we see a bit of a jump in energy. The morning has 4ft from the SE at 8 seconds (357 energy), with a clean cross-off wind. Not bad for a grovel session. Then that afternoon, the period suddenly jumps to 14 seconds for a S swell, but it’s tiny at only 2ft. That’s a very long period for such a small wave, so it’ll be super inconsistent and glassy. It may bring a few set waves that stand up nicely, but you’ll be waiting a long time between them.
The best of the best in this whole outlook? I’m not hyping it up, but I’d aim for Tuesday morning the 8th of September for some clean, glassy waves, although the short period isn't ideal. It's the most “normal” surf we see.
If you’re willing to gamble on a long-range pick, Wednesday morning the 16th of September has that higher energy (357) and clean wind. The swell direction (SE) is a bit off the optimum for Praia de Asturias (E), but it’s the most promising of the second week. Just know the mid-range is a total desert. It’s a quiet stretch for Asturias.
Rusty, signing off.

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. Our Praia de Asturias surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
