The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for the Sardinero stretch over the next couple of weeks.
First up, we’re talkin’ about El Sardinero - Segunda (Spain). The water temp is sittin' at 71.2°F, which is a touch warmer than normal for this time of year – not a bad thing if you’re in a spring suit.
Right off the bat, there’s a bit of a gap. The first wave worth paddling for isn’t until Tuesday morning, September 1st. The Monday afternoon beforehand is a write-off – a messy 5.9ft groundswell from the NW with a period of 10 seconds, but the wind is all wrong. That combined energy is moderate at best (672), and the report calls it marginal.
Now, the standout. Tuesday morning, September 1st, is where you want to be in the water. We’ve got a 3.9ft NW groundswell (10-second period), and more importantly, the wind is glassy. Absolutely dead calm, with a light NE air. That’s a rare treat for this spot. The combined swell energy is a solid moderate (273) and it’s expectin’ good surf conditions. For the morning session, it doesn’t get much better than that. The break is fairly consistent, and it's a beach-and-rocks setup that handles NW swell well. Just keep an eye out – crowds can show up here sometimes.
The rest of the week drops off hard. Wednesday and Thursday are plagued by onshore winds, with swell dropping to a pathetic 0.7ft to 2.0ft (periods as short as 8 seconds). That combined energy drops into the weak zone (9 to 55). Forget it.
The weekend? Saturday morning, September 5th, sees a pulse of 3.3ft NW swell, but it’s back to a 12-second groundswell with onshore wind. The energy is moderate (266), but the wind is a dealbreaker – it’s junk.
We get a bit of a tease the following week. On Tuesday morning, September 8th, there’s a tiny 2.0ft WNW groundswell, but the wind is glassy again and the period is a long 11 seconds. The energy is low (120), and the report says it’s “surfable waves but very ordinary conditions.” That’s about as generous as it gets for a close-out beachie on a long-period groundswell.
Then there’s a spike around Thursday, September 10th. A 5.6ft NW groundswell (9 seconds) on Thursday morning builds to 6.9ft (10 seconds) by the afternoon. The combined energy jumps up to strong (439 and then 810), but the wind is cross-onshore. That’s marginal, and at that size, it’s not for the groms, but the experts might find some punchy walls. Still, it’s a beach-and-rocks setup, so the long-period nature might make it a bit wonky.
After that, it’s a long dead spell. From the 11th through the 15th, we’re looking at a complete blank run. The swell evaporates, and the wave comment reads “poor surf conditions” or flat lines of zero energy. So, for surf, that last week is mostly a write-off.
Best on Offer: Lock in Tuesday morning, September 1st. Glassy conditions on a clean 3.9ft NW swell is the only real highlight. The Thursday the 10th spike is big and punchy, but the wind keeps it from being perfect, so it's a worthwhile consolation if you're around.
