The Lowdown
Alright, Rusty here. Let's talk about what's cooking for the Asturias stretch.
Honestly, for the next week and a half, it's a pretty bleak picture. We're looking at a long stretch of marginal to poor conditions, with only a couple of brief windows where things get interesting. The first real gap is from the 27th of August right through to the 7th of September, with very little to get excited about. The water temp is sitting about average for the time of year, nothing wild there.
The standout session, and the one to circle, is the afternoon of the 7th of September. The swell is coming from the ESE at 5ft, and even though the period is a short 7 seconds, the wave energy is moderate (547). The real kicker is the wind: light and cross-offshore from the SW, which will keep things clean. It's a beach and reef setup, so that short-period swell might actually offer up some fun, punchy walls. There's a decent chance of crowds, so get out there early.
The other session to keep an eye on is the afternoon of the 8th of September. Again, light cross-offshore wind from the WSW, with a 4ft ESE swell. The energy is moderate (435) and the conditions should be clean. It's a good backup for the day after the main event.
The morning of the 11th of September also shows a glassy calm with a 2ft SE swell and a long 14-second period, which will be clean but small. It's a long-period groundswell, so it might break a bit straight on the beach, but it'll be pretty.
Everything else is a write-off. The wind is either onshore, cross-onshore, or too strong, and the swell is tiny or short-period. There's a lot of "poor surf conditions" in the data, so don't bother until the 7th.
Rusty.
