The Lowdown
Alright, this is Rusty. Lookin' at the next couple weeks here, and honestly, it’s a slow start. We’ve got some small, weak swell rolling in, but nothing worth paddling out for until we hit the middle of next week. After that, there’s a real gap of about a week where it’s basically flat or junk, before a very promising late-season pulse shows up right at the end of the window.
Here at Praia de Asturias (Asturias), it’s a beach and reef setup, beginner-friendly but inconsistent. The water is sitting at 71°F, which is a touch warmer than normal for this time of year.
Alright, let’s get into it. The first real glimmer is on Wednesday, August 12, morning. We’re looking at 5ft of swell from the SSE with a 12-second period, and the wind is calm – glassy conditions. The energy is moderate (558). It’s small, but clean. That’s your best chance in the first week.
Thursday, August 13, afternoon could be another one to keep an eye on. The swell drops a bit to 4ft, but the period stretches out to a nice 15 seconds (groundswell), and it’s glassy again. The combined energy is moderate (676). That long period will give you longer lulls between sets, making it easier to get out, but it might close out a bit on a beach break. Still, clean surf on offer.
We get a few more glassy mornings with small 4ft to 4ft SSE swell, like Friday, August 14, morning and Saturday, August 15, morning. The energy is moderate but dropping (423-512). These are alright for a longboard or a foiler.
Then the wheels fall off. Sunday, August 16 starts glassy but with a short, weak 8-second period, and it gets worse from there. From the 17th right through to the 24th, it’s mostly poor conditions, onshore wind, and teeny waves. A long stretch of nothing. On the 24th, a little 3ft S swell shows up with a glassy morning and a 12-second period, but the energy is still low (229). Not worth a special trip.
But hold onto your board. The real standout is set for Tuesday, August 25, afternoon, through Wednesday, August 26, morning. This is the one. On the 25th afternoon, the swell jumps to 6ft from the SSE with a very long 17-second period. The combined energy is strong (2009). Then on Wednesday, August 26, morning, we get 6ft from the SSE, a 15-second period, and the wind is offshore from the WNW at just 3 mph. Clean. The energy is very strong (1535). This is the best we’ll see all window – a proper groundswell with power and shape. That long period will work great at this reef setup, making for some lined-up, punchy waves. It’s expert-level size (over 8ft), so it might be a bit much for the beginners.
The afternoon on the 26th gets a little chopped as the wind swings onshore, but the morning session is where it’s at.
Keep an eye out for crowds, as this spot can get them sometimes, especially when a solid swell like that shows up.
So, to sum it up: a few clean, small days mid-week next week, then a big pause, and then a powerful groundswell hits on the 25th and 26th. That’s the one you want to be here for.
Stay icky.

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.
