The Lowdown
Alright, let’s get into it. The next couple of weeks are looking pretty flat and quiet, with a few clean but tiny windows. We’ve got a lot of small swell and light winds, but the standout moments are few and far between. The water’s sitting at a warm 72°, which is a touch warmer than usual for this time of year—nothing crazy, but you’ll notice it.
Right now, we’re looking at a mostly poor stretch. Monday the 14th has a little cross-on swell at Praia de Asturias, but it’s messy and small—around 3ft with a short 7-second period. Not worth paddling out for anything serious. The afternoon is cleaner but still tiny, just 3ft, and the energy is weak (130). The next few days follow the same pattern: small waist-high waves, some glassy moments, but nothing with any push.
The first real glimmer comes on Saturday the 19th. We get a jump in size to 5ft from the ESE, but the period is only 8 seconds, so it’s going to be lumpy and a bit messy. There’s a bit more energy in the water (475), but the wind is onshore and it’s not going to be pretty. This one’s for the dedicated crew, not the casual surfer.
Sunday the 20th sees the biggest swell of the whole run—7ft from the east with a better 9-second period, and the energy jumps right up (872). But the wind is cross and strong, making it a chop-fest. The setup looks more interesting for a kite session than a paddle. It’s got power, but it’s not clean.
After that, it fades out fast. Monday the 21st is glassy but tiny—3ft—and then we hit a flat spell. Tuesday and Wednesday are practically nothing, with waves dropping to 2ft and the energy bottoming out to 34. Then we get a little pulse on Monday the 28th with 3ft and a clean cross-off wind, but the period is back up to 11 seconds, which means it might be a bit too lined up for the beach breaks. Still, it’s the cleanest surf of the second week.
Honestly, if you’re looking for the best of what’s on offer, Saturday the 19th and Sunday the 20th have the most size, but conditions are rough. The cleanest waves will be Monday the 28th, but they’re small. There’s nothing here that’s going to blow you away. The long-range stuff is promising but uncertain, so don’t book your week off just yet.
This is a stretch where patience is key. The waves are there, but they’re not singing. Keep your eye on the 19th and 20th for size, and the 28th for clean lines. Otherwise, it’s a board waxing kind of week.

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.
