The Lowdown
G’day, Rusty here. Let’s have a look at what’s coming up for Praia de Asturias (Asturias).
Right off the bat, the next 16 days are a bit of a mixed bag for this sheltered beach and reef setup. The waves are gonna be small, mostly under 5 ft, and the wind is going to be a major player. There’s not a lot of proper quality on offer, with long stretches of poor conditions in between some cleaner windows. The best bet looks like a short window early on, then a long, flat, or messy run.
We kick off on Saturday the 15th of August with a bit of something. The morning is cloudy with a moderate cross-off breeze from the WSW at 12 mph, pushing into a 5 ft swell from the SSE with a 13-second period. The wave energy is moderate (732). Water temp is sitting at 70°, a touch warmer than normal for this time of year, which is nice. It’s a bit marginal though, not the cleanest. The afternoon cleans up with lighter winds, 6 mph from the WSW, and a 5 ft SSE swell. This is your best window for a paddle, but it's still not a standout. The swell direction is from the SSE, which isn’t the optimum east direction for this break, so the quality may be a little ordinary.
Sunday the 16th of August starts off with a real treat. Morning is clear, glassy conditions with an east-northeast breeze at just 3 mph, and a 5 ft swell from the ESE at 8 seconds. The wave energy is moderate (579). That glassy wind is a massive positive, and it’ll be clean. But the period is short, so it’s a windswell, a bit soft. The afternoon turns onshore from the ESE at 12 mph, making it a write-off.
Monday the 17th of August has a small, clean 4 ft ESE swell in the morning with light cross-off winds, but it’s ordinary. The wave energy is low (224). That sets the tone for the rest of the run.
From Monday afternoon all the way through to Friday the 21st of August, it’s a long, slow grind. The swell drops below 3 ft, the wind is often onshore, and wave energy plummets into double digits. There’s a brief moment on Friday the 21st with a 2 ft ESE swell and a light cross-off breeze, but it’s not worth chasing. The next standout doesn’t come until Sunday the 23rd of August. The afternoon brings a moderate cross-off wind from the SW at 9 mph, pushing a 4 ft SSE swell with a 13-second period. Wave energy hits a solid moderate (584). Conditions should be clean, but the swell is from the SSE again, not the optimum east.
After that, it gets messy again. Strong, onshore winds, rain, and a lot of cross-onshore chop dominate from Monday the 24th of August right through the end of the month. There’s a very long-period SSE swell on Monday the 24th of August (16 seconds) pushing 6 ft, but the wind is cross-onshore and choppy. The wave energy is strong (1358), but it’s completely blown out. The swell direction is also not ideal for this break. This is more of a kite-surfing setup than a paddle-surfing one.
There’s a tiny window on Friday the 28th of August with a glassy 3 ft SSE swell, but it’s small, and then Saturday the 29th of August morning has a glassy 4 ft ESE swell, which is a better direction, but still small and with a short period (8 seconds).
Overall, the only real window for a decent, clean surf is Sunday the 16th of August morning. It’s the standout. The conditions are glassy, the swell is rideable for a beginner, and it’s about as good as it gets in this forecast. The Sunday the 23rd of August afternoon is a promising, clean option further out, but it’s less certain at this range. For the rest, you’re looking at small, choppy, or blown-out conditions, especially from the middle of the second week. The crowds are listed as “sometimes” on this spot, so you might have it to yourself on that Sunday morning.
Stay patient, check the charts closer to the day.
