The Lowdown
Alright folks, Rusty here. Let’s take a good, hard look at what’s cookin' for El Sardinero over the next couple of weeks.
Honestly, for the first stretch, it’s a bit of a flat spell. There’s a gap with no real surf to speak of from now through the end of August. The first hint of anything rideable doesn’t show up until Thursday the 20th, and even then it’s nothing to get excited about. The pattern is for small, weak swell with poor conditions ruling the roost for the first week or so.
The standout window, if you can call it that, opens up around Saturday the 22nd. El Sardinero - Primera sees a small pulse of NW swell, 4 ft, with a period of 9 seconds. The big news here is glassy conditions that morning. The combined energy sits at 217 (moderate), and with the wind dead calm, the surface will be like a mirror. You’ll be paddling out into clean lines, but it's small, so take a log or a fish. The water temp is about average for the time of year, so no surprises there.
The following week holds a few more moments. Saturday the 29th morning looks similar: glassy, with a 4 ft NW swell. The combined energy is a bit weaker at 175, but with the wind off the water, it’ll be clean and fun on the longboard. The crowd factor is something to keep in mind here – this spot is often busy, so you’ll want to be early for those glassy windows.
After that, we roll into September. Tuesday the 1st and Wednesday the 2nd both offer clean, cross-off conditions with a consistent 4 ft NW swell. The energy picks up a bit to 250-266, so there’s a little more push. The wind is light and offshore, making for some tidy, peelable waves. It’s not big, but it’s your best bet for a decent session.
Bottom line: it’s a flat and funky start, but the second week has some clean, small-wave windows. Don’t expect a bomb, but you won’t be skunked if you pick your mornings.
Rusty.
