The Lowdown

Alright, let me have a look at what’s coming up for us here. There’s some swell on the horizon, but honestly, it’s going to take a little patience to get a window of real quality at Praia de Asturias (Asturias). We’re in for a bit of a slow start, and the first week is pretty ordinary, but the second week brings one clear standout that should get the juices flowing.

The action kicks off on Monday the 31st of August, but it’s nothing to write home about. We’re looking at tiny 1 ft swell out of the ESE with a short 8-second period and weak combined energy (33). That’s just windswill with rain showers and a weak cross-on breeze—stay home. That afternoon is even worse with 2 ft and a 4-second period, so there’s no point even checking it.

Tuesday the 1st of September shows a bit more life. The morning brings a 3 ft S swell, 6-second period, and moderate combined energy (136). Wind is cross-off from the north at 9 mph, so it’s clean, but the swell is small and short-period. Surfable but very ordinary. The afternoon is similar with 3 ft and clean cross-off breeze. Still, not worth rushing for.

Wednesday the 2nd drops off again with only 2 ft in the morning and then a weak 3 ft cross-shore junk in the afternoon. Thursday the 3rd has a little more pulse: 3 ft of SSE groundswell, an 11-second period, and moderate energy (243) in the morning with glassy conditions. That’s the first moment the place actually looks fun—clean, long-period swell, but it’s still small. The offshore wind direction is not in the optimum (E), so it doesn’t line up perfectly for the sheltered setup. Still, a nice session for a longboard or a foiler.

Friday the 4th has glassy 2 ft in the morning but that’s about it. The weekend is a write-off with rain and strong cross-onshore wind building into Sunday, when a bigger 6 ft S swell rolls in but with a 12 mph southerly making it a messy, choppy mess. Wave energy jumps to 1052 (very strong) but it’s blown out—this is more for kites than paddle boards.

Then comes the big promise: Wednesday the 9th of September. Dawn patrol is glassy—dead calm, winds calm, 4 ft of SE groundswell with a 10-second period and strong combined energy (510). That’s a proper surf day with clean lines and a bit of push. The swell direction (SE) is not the optimum (E), but it’s close enough and the conditions are perfect. This is the best on offer—no crowds mentioned, which is a bonus at a spot that’s sometimes busy.

Thursday the 10th of September morning is also glassy but the swell drops back to 4 ft and the energy falls to 317. Still very surfable but the standout is the day before. After that, it fades through the weekend with small, weak swell and onshore junk.

The last real chance is Monday the 14th of September morning: glassy, 2 ft SE swell, 10-second period, and weak energy (106). It’s small and clean, more of a cruise than a chase.

So, to wrap it up: there’s a big gap of poor to ordinary surf from the start through the first week. The clear standout is Wednesday the 9th of September morning—get on it. After that, it goes quiet again. The water temp is about average for this time of year, nothing out of the ordinary.

Stay patient, that Wednesday glass-off is the one.
