The Lowdown
Alright, surf is gonna be a bit of a waiting game for the next week and a half, to be honest. We’ve got a long stretch of small, jumbled, and mostly blown-out conditions ahead. The energy is just not there, and the wind is often coming from the wrong angle for the spots we’re looking at. It’s gonna test your patience, that’s for sure.
The first real pulse of anything rideable shows up on Sunday the 16th. It’s not going to be epic, but there’s a glimmer of hope. The morning looks like the pick, with a clean, glassy vibe and a little pulse of NW swell around 3ft. The period is a meagre 11 seconds, so it’s not going to have much grunt, but at least it’s clean. The energy is still moderate, with a combined value of 249. It’s surfable, but it’s not going to be anything to write home about.
Monday the 17th has a similar story in the morning – clean and glassy again, with 3ft of NNW swell. It’s small, but at least the surface will be smooth. The period drops off to 9 seconds, so it’s pretty soft and weak. The energy takes a step back to 114, so keep your expectations in check.
Now, here’s where things get a little more interesting. The real standout of this whole window is shaping up for Tuesday the 18th and Wednesday the 19th. Tuesday morning sees a jump in swell to 8ft from the NW, with the combined energy jumping right up to 790. There’s a bit of cross-shore wind, so it could be a bit lumpy, but there’s some size to play with. The afternoon pushes even bigger, with 8ft of swell and a strong energy reading of 1371. That’s a solid step up, but it’s getting into expert-only territory with that size.
The real gem though, the one to circle on the calendar, is Wednesday the 19th. The morning is looking special. We’ve got 6ft of good NW swell, a solid 10-second period, and light offshore flow keeping things clean and lined up. The combined energy is strong at 787. This is the one. This is the day you want to be out at El Sardinero - Primera. The swell direction is dead on from the NW, which is what this spot wants to see. It’s going to be good. The afternoon turns more onshore and the quality will drop, so make the most of the morning.
After that, the swell fades back down on Thursday the 20th, with a smaller 3ft and a short 7-second period. It’s back to the small stuff.
So, to wrap it up: the first week plus is a write-off for anything decent. Keep your board in the car, but don’t get too excited. The window to focus on is the morning of Wednesday the 19th. That’s the standout. It has the size, the right direction, and the clean wind. It’s a few days out, so keep an eye on the forecasts, but that’s the one that’s got me amped.
