The Lowdown
Alright, Rusty here. Let’s talk about what’s showing up for El Sardinero.
Right off the bat, I gotta be straight with you – this is one of those stretches where the ocean just isn’t cooperating. The next week and a half is basically a flat spell with hardly any energy. From Thursday, July 30th, all the way through to Friday, August 7th, the swell is tiny, often below 0.6m. The wind is mostly okay, with some clean windows, but with such small, weak swell (combined energy values sitting between 2 and 57), it’s just not worth paddling out. The water temp is about average for this time of year, nothing to write home about.
There’s a long gap of almost no surf until we get to the only real window of the whole outlook. That comes up on Saturday morning, August 8th. This is the standout, the only one worth setting the alarm for.
On the morning of Saturday, August 8th, El Sardinero - Segunda finally gets a little pulse. We’re looking at clean, glassy conditions with a 0.9m NW swell, period around 9 seconds. The combined energy jumps up to 118 (moderate wave energy). It’s offshore, light air, glassy – that’s about as good as it gets for this spot, and it’ll be a fun little session. Keep in mind, El Sardinero is a beach and rocks setup, so watch your feet on the low tide. Crowds are sometimes an issue here, so get on it early.
After that Saturday morning window, the 0.9m to 1.0m swell hangs around into the afternoon, but the wind goes cross-shore and it gets a bit messy. By Sunday, August 9th, the swell is dropping again and the wind turns sloppy. Then from Monday, August 10th onwards, we’re back to barely a ripple, with combined energy dropping to just 2 or 4. Honestly, after that Saturday morning, it’s not worth checking again for at least the next few days.
So, to sum it up: don’t even bother checking the surf until Saturday morning, August 8th. That’s your best bet by a mile – a clean, glassy little window with a knee-to-waist high NW swell. The rest is a write-off.
