The Lowdown
Alright, let’s get into it. Things are looking slow and small for Asturias for quite a while. The first stretch is really nothing to get excited about; we’re looking at a gap of a few days with no real surf to recommend. The first proper surfable session isn’t until mid-week next week, and even then it’s not a standout.
So, let’s start with the first bit of hope. Tuesday, September 15th is the first time we see decent conditions. Praia de Asturias will have a clean, glassy afternoon. The swell is small though, only 2ft from the south with a long period of 14 seconds – that’s a proper groundswell. The water is about average for this time of year. The combined energy is a moderate 419, and that glassy wind will make for clean shapes on the reef and beach setup. Still, with the optimum swell direction being east, this south swell is a bit angled, so it won’t be hitting perfectly. It’s a quiet option.
The next potential highlight is Wednesday, September 16th in the morning. Glassy conditions again at Praia de Asturias, with a bit more size coming in at 5ft from the south. The period is short at 7 seconds though, so it’s a weak windswell. The energy is a moderate 443. It’s a better bet than the previous days, but still nothing bomb. The afternoon gets ruined by onshore wind and a storm risk, so get in early.
Looking further ahead, the long-range window for the second week stays mediocre to poor, with most sessions getting marked down for poor surf. There’s a brief window on Monday, September 14th afternoon where we see a 3ft south swell with a very long 16-second period and a clean cross-offshore wind – energy is a strong 407, but the height is too small to call it a standout. Too much wait for too little reward.
Overall, the best true standouts are Tuesday the 15th afternoon and Wednesday the 16th morning. Forget the rest; most of this forecast is a write-off for decent waves.
