The Lowdown
Alright, Rusty here. Gotta be straight with you—this 16-day window for El Sardinero - Segunda is a tough one. We're looking at a long, dry spell of poor surf conditions right from the get-go. From Monday the 17th of August all the way through to the morning of Monday the 25th, it's basically flat or so small and choppy it's not worth paddling out. That's over a week of nothing but small, weak swell or no swell at all. The water temp is sitting around average for the time of year, nothing weird going on there.
The first sign of life doesn't show up until the morning of Tuesday the 25th. We get a pulse of 5ft swell from the northwest, with a short period of 8 seconds. The combined energy is a moderate 241. It's not big, but the wind is blowing gentle offshore from the west. That means clean, lined-up little waves for El Sardinero - Segunda. It's a beach-and-rocks setup, fairly exposed to the north-northwest, so it'll pick up that swell okay. It's just "surfable" though, nothing to write home about. Crowds can show up here sometimes, but on a tiny Tuesday you might have some space.
Then we go flat again for a few more days.
The one true standout, the one that might actually be worth circling on the calendar, is the morning of Sunday the 30th of August. Overnight, the swell builds to 5ft from the northwest, with a 10-second period. That's a decent groundswell, and the combined energy jumps to 476 (moderate to strong). But the magic is the wind: absolutely glassy. Light rain clouds, but zero wind. That’s going to make El Sardinero - Segunda look as clean as a mirror. It's still only a 3 out of 10 on the score, so don't expect perfection, but it's the best we've got in the whole run. The afternoon gets wrecked by a fresh 30 km/h cross-offshore wind, so hit it early. This is the call for the experienced crew; 5ft might be a bit too much for beginners.
After that, we're back to nothing until we run out of forecast. It's a lean couple of weeks.
Rusty.
