The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for El Sardinero over the next couple of weeks. Gotta be straight with you – it’s a lean stretch. The first real sniff of anything rideable doesn’t show up until the very end of the run, so we’re looking at a long, dry gap of about two weeks where the waves just aren’t there. The swell energy is weak or non-existent, and the few tiny pulses that pop up are paired with poor conditions.

For the first two weeks, from the 15th through to the 28th of August, it’s mostly flat or ankle-biters. You’ll see some tiny 2 ft NW swells early on, but the combined wave energy is pitiful – barely cracking a couple dozen. The wind is either onshore, cross-shore, or just messy. Even the glassy mornings on the 17th and 19th only have 0.3 ft of swell. There’s nothing to ride. The 25th shows a tiny bump with a long period groundswell from the NW at 14 seconds, but at only 0.3 ft, it’s a ghost.

Now, the standout window – and I mean the *only* window – is the morning of Wednesday the 26th of August. That’s your best bet. El Sardinero - Segunda (El Sardinero - Segunda) will see a NW swell at 4 ft with a long period of 12 seconds. The combined energy finally gets some legs at 389 (moderate energy). This is a proper groundswell, so the shape should be there, but with a NE wind blowing 3 mph onshore, it’s gonna be a little lumpy. Still, it’s the biggest, most energetic swell of the whole forecast. It’s intermediate level – the size is manageable, but don’t take beginners out. That same afternoon the wind picks up, so hit the dawn patrol.

The following morning, Thursday the 27th, has a similar 5 ft NW swell with a 10-second period, but onshore E winds at 9 mph make it choppy and a bit of a mess. Not worth it compared to Wednesday morning.

By the 29th and 30th, we get a little glassy morning on the 30th with 3 ft NW swell and 9-second period, combined energy of 152 (moderate energy). The wind is glassy calm – a total zero. That would be clean, but the swell is weaker and the direction isn’t optimum. It’s a fallback option.

The water temp is sittin’ pretty average for this time of year, nothing unusual to report. Crowds can be a factor here at El Sardinero, so on that Wednesday morning, expect some company.

So, to sum it up: it’s a long, quiet stretch, but the morning of the 26th of August is the one to pencil in. Set the alarm, get out there, and hope the onshore breeze holds off a little longer.

Rusty.
