The Lowdown
Alright folks, Rusty here. Let’s get into it for Praia de Asturias. This is a tricky little stretch of coast, a sheltered beach and reef setup that can be a bit of a tease. The water temp is about average for this time of year, so nothing wild on that front.
Straight off the bat, we’ve got a bit of a wait. The first few days are a mixed bag of weak, short-period swell and average to poor conditions. Through Wednesday and Thursday of this week, the swell is small and the wind is mostly cross or onshore, leaving things messy. The combined energy is weak, barely cracking 250 (moderate), and the waves are just not standing up. Friday morning is a tease with glassy conditions but only 3ft of long-period swell, which is too weak to get excited about.
Things fall away over the weekend. The swell drops to just 1ft on Saturday, and the combined energy plummets to 75 (weak). It’s a dead period. Sunday and Monday are only slightly better with short-period windswell, but the wind is onshore and the energy is still moderate at best. The setup is more interesting for kite surfing than paddle surfing those days.
The first real standout is Thursday, September 10th. The swell picks up to 5ft from the ESE, with a period of 8 seconds. The combined energy jumps to 685 (moderate to strong), but more importantly, the wind is glassy all day. That’s a big deal here. Expect clean, surfable waves at Praia de Asturias. The crowd factor is a possibility – it’s listed as sometimes busy – so get in early. The swell direction (ESE) is a bit off the optimum (E), but the glassy conditions make up for it.
After that, the energy drops back down. Friday and Saturday see a return to 3ft and 2ft swell with onshore wind, so it’s ordinary again. There’s a long gap of poor conditions through the middle of the month.
The second standout is Wednesday, September 16th. The swell is a consistent 5ft from the SE, with a period of 10 seconds. The combined energy is 452 (moderate). The morning session looks prime with glassy conditions – that’s your best bet. The afternoon turns cross-offshore, which cleans it up but might shut it down. This is a promising one, but being over a week out, treat it as a hopeful call rather than a lock.
Overall, it’s a quiet window for Praia de Asturias. The two standouts are the 10th and the 16th. Get on them if you can.
Rusty.
