The Lowdown
Alright folks, Rusty here with the surf check. Gotta be honest, the beginning of this forecast is a total bust. A long stretch of nothing from Tuesday the 18th of August right through to the morning of Thursday the 27th. Over a week of flatness. Water temp at El Sardinero - Segunda is about 73°, which is a touch warmer than usual for the season, but that doesn’t help us when there’s no waves.
First sign of life shows up Thursday morning the 27th. El Sardinero - Segunda (Spain) gets a tiny NW swell pushing 3ft with an 8-second period. Energy is moderate (143), and we’ve got a light offshore breeze. It’s surfable but nothing special. Thursday afternoon the swell inches up to 3ft, but the wind goes cross-shore and it gets a little messy.
Friday the 28th looks a bit cleaner. Glassy morning, calm wind, same 3ft NW swell, but the period stretches to 10 seconds, giving it more juice. Energy is moderate (142). Saturday the 29th is similar with another glassy morning—calm winds, 3ft NW swell at 9 seconds. These days are fine for a log or a funboard, but just okay.
Now, here’s the real nugget. If you can wait, Tuesday the 1st of September sees a solid jump to 6ft from the NW with an 11-second period. Energy is strong at 677. The wind is onshore in the afternoon, so the morning might be better. But Wednesday the 2nd of September is the one. Morning brings 5ft of NW groundswell, 11-second period, and a clean offshore wind from the west. Energy is strong (600), conditions are good. The afternoon gets even better: 6ft from the NW, 11-second period, and a moderate offshore wind. Energy climbs to 741, and the forecast says *very good* surf. That’s the session to circle.
Crowds at El Sardinero - Segunda are listed as “sometimes,” so you might see a few heads out, especially for that Wednesday. That NW groundswell is right in the break’s wheelhouse. The longer period (over 11 seconds) means more power and better shape, but at this beach-and-rocks spot, the sets will come with longer lulls. Paddling out should be easier between the bombs.
So tough it out through the flat spell, maybe grab a few weak ones on the 28th and 29th, but save your energy for Tuesday afternoon and especially Wednesday the 2nd of September. That’s the real deal.
Rusty.
