The Lowdown
Alright, this is a tough one for you, Asturias. Honestly, looking at the full 16-day window, there are no real standouts, and the whole region is going to be a bit of a challenge. We're looking at a long stretch of small, weak, and mostly messy conditions.
The good news is we have a very sheltered setup here, so it doesn't take much to get it clean. Right now, on Wednesday the 19th, the water is sitting at 69°F, which is a touch warmer than normal for this time of year, so you won't need a thick suit.
The first few days are a write-off. The swell is tiny, under 2ft on the 19th, with a weak combined energy of only 38, and it's coming from the wrong direction for this spot. The wind is good early on Wednesday with glassy conditions, but there’s just no push.
We finally get a bit of a pulse late on Friday the 21st, with a 4ft south swell pushing the energy up to 284, but it's short period at 7 seconds and the wind is a messy cross. Not worth paddling out for.
The real action, if you want to call it that, starts to build on Monday the 24th. The swell gets bigger, hitting 6ft from the SSE by the afternoon, with a long period of 14 seconds and a massive jump in energy to 1380. That's a lot of power, but it's coming straight onshore, making it a mess. That's a kite-surfing setup, not a clean surfing one.
The only window that looks genuinely good, and I mean the *only* one, is the morning of Tuesday the 25th. We've got a 4ft south swell, a long 14-second period, and the energy is solid at 669. The wind goes absolutely dead calm, turning it glassy. This is the best the whole 16 days will offer. The swell direction is a bit off-optimum for this sheltered spot, but the conditions will be so clean that it'll be the pick of the period.
After that, it drops back to small and messy for the rest of the week. We get another pulse around Thursday the 3rd of September, with a 4ft swell from the south, a 13-second period, and 542 energy. It's clean in the morning with a light offshore, so that's your second-best option, but it's a long way out and the forecast confidence is lower.
So, to sum it up: don't hold your breath for the first week. The standout is the morning of Tuesday the 25th. Get out there if you can, because it's the only real clean window in the whole forecast. The rest is a waiting game for some better direction.
