The Lowdown
Alright, Rusty here again. Let's size this up in feet and miles per hour.
It's a slow burn for the Sardinero zone. The first decent surf window doesn't open until the morning of the 17th of September. Before that, it's a whole lot of small, choppy, onshore slop. The wind is the enemy for a solid week.
The clear winner is the morning of the 19th of September. It's not the biggest swell, but the conditions are going to be perfect. For El Sardinero - Primera, we're looking at clean, glassy conditions with a 4ft swell from the NW at a 13-second period. The wind is dead calm, making it look like a lake out there. The water is 71°, which is a hair warmer than usual, so a spring suit is all you'll need.
The other one to circle on the calendar is the morning of the 24th of September. It's a long way out, so don't book the day off work yet, but the setup is promising. A 5ft swell from the NW with an 11-second period, and a light offshore wind from the west. That means clean, peeling waves. The energy in the water is solid, too.
The morning of the 17th is the first real chance you'll get. A 5ft NW groundswell and clean, offshore west wind. It's surfable, but it's not the standout.
The rest of the chart is a mess. The 13th of September has some size, hitting 5ft, but a strong onshore wind will chop it up into a washing machine. That's a kite-day, not a surf-day.
So, to sum it up: the first week is a no-go. The 19th is your best bet for a glassy, fun session, and the 24th is a hopeful long-range target. The rest is just a waiting game.
Rusty.
