The Lowdown
Listen up, crew. Rusty here. For this stretch, we're gonna have to be patient. There's a lot of junky, blown-out days, but a couple of absolute gems hidden in there if you can read the forecast.
It’s quiet and messy from the 14th through to the 17th of September. Small swell and onshore breezes are making a mess of things. Don't bother paddling out. The water temp is about what you'd expect for this time of year.
The first real highlight is Thursday morning, the 17th of September. Swell comes up to 5ft from the NW, with a 11-second period – proper groundswell. The combined energy is moderate (592), and the wind is light offshore from the W, keeping it clean. El Sardinero - Primera is your spot, it's fairly consistent and sheltered, though you’ll have the crew out there often. That’s a solid session.
We get a bit of a lull before a bigger pulse shows up on Friday afternoon, the 18th. Swell jumps to 7ft from the NNW with a very long 15-second period, and the combined energy is very strong (2005). It’s a lot of water moving, but the wind is light cross-onshore, so it's not going to be perfect. That size is only for the experienced crew.
Saturday the 19th keeps the size around 7ft in the morning with a 13-second period and very strong energy (1551), but the wind stays cross-onshore. By the afternoon the wind picks up and it’s choppy. Tough conditions.
Now, the absolute standout of the whole outlook is Tuesday morning, the 22nd of September. The swell is a beautiful 6ft from the NNW with a 13-second period and high energy (995). And the wind? Dead calm. Glassy. Zero wind. El Sardinero - Primera will be an absolute sheet of glass with that much groundswell running. This is the one you wait for. The water temp will be about average, but the conditions will be world-class for a sheltered spot.
After that, the swell drops. Wednesday the 23rd morning is glassy but small at 3ft, and then we’re into a long stretch of small, wind-affected surf right through to the 29th of September. There are a few clean moments, but not enough wave height to get excited about.
So, to wrap it up: hit Thursday morning the 17th for the first clean swell, but the big one, the one to circle in red, is Tuesday morning the 22nd. That glassy 6ft NW swell is a gift. Don't miss it.
Rusty.
