The Lowdown
Alright, let's get into it.
Overall, it’s a bit of a mixed bag coming up for Praia de Asturias. We've got some small windows of clean surf but plenty of days where the wind and conditions just aren't cooperating. The water is sitting at 71°, which is a touch warmer than usual for this time of year – nice for a longer session.
Right now, Monday the 7th is a write-off with a messy onshore wind and marginal surf, so don’t bother.
Things turn around first thing Tuesday morning, September 8th. We’ve got a glassy 3ft swell from the SSE, with a period of 10 seconds. The combined energy is moderate at 233. The wind is a glassy southwesterly, and it’s going to be clean as a whistle. It’s small, but for a beginner-friendly spot like this, that’s actually a good thing – easy paddling, no stress. Tuesday afternoon stays clean with a light cross-offshore breeze.
We then hit a long, frustrating patch. From Wednesday the 9th right through to Monday the 14th, it's mostly poor conditions – onshore wind, questionable tides, and general choppiness. There’s a bit of energy on Sunday the 13th with a 6ft S swell and a very strong energy reading of 1174, but the wind is onshore and trashy. Not worth it.
The next real standout is looking promising but further out. Wednesday morning, September 16th, is one to circle on the calendar. We get a glassy 4ft from the south, 10-second period, combined energy of 442 (moderate). The wind is light, almost calm, making for a glassy surface. This will be the best quality surf in the whole run – super clean, fun size for the lineup.
Then there's another promising window on Saturday morning, September 19th. Another glassy start with a 4ft, 14-second period groundswell from the south. That longer period means more push and better shape, especially for a beach and reef setup. The energy is strong at 697. This one is a little more powerful, so if you’re a beginner, be careful – that’s a bit more water moving around.
Finally, Sunday morning the 20th offers a glassy 5ft from the ESE, but with a very short period of just 7 seconds. The energy is moderate at 413, but the short period means it’ll be a bit weaker and more disorganized. Still, glassy conditions will make it ridable.
Honestly, the best days here are the 16th and the 19th. The 16th is the better bet for clean, user-friendly waves. The 19th has a bit more power but is still clean. Everything else is either too small, too windy, or not breaking well.
Keep your eyes peeled on that Wednesday the 16th.
