The Lowdown
Alright crew, Rusty here with the lowdown on Playa de Seaia for the next couple weeks. Let's get real about the surf.
It's a slow burn, honestly. The beginning is all wind-affected and messy. But if you can wait, the second half has some big energy coming through, with a couple of proper standouts.
Water temp is 65°, right about what you'd expect for this time of year.
First real chance to wet a line is Monday the 14th. The morning is glassy with a light southerly breeze. We're looking at 3ft of NW swell with an 11-second period – combined energy at 281 is solid. It's clean, the direction is good, and it'll be a fun, easy session for all levels.
After that, it's a dry spell for nearly a week. Wind is on it or the conditions are just choppy and unappealing.
Now, keep your calendar clear for Sunday the 20th of September. This is the big one. A powerful NNW groundswell hits, 10ft with a very long 15-second period. The combined energy reading is a massive 4241. Morning wind is manageable, just a light cross-onshore. This is heavy, expert-only territory – way over the 8-foot mark. With that period, it's going to be a beast, likely a bit straight and charging at a beach break, but the power will be undeniable.
Also worth noting is Saturday the 26th. Another solid NW groundswell, 8ft in the morning with a 12-second period and light offshore airflow. Combined energy is at 2061. It's a big day, but if the wind plays ball, it's another one for the experienced crew.
So the two moments to circle are Monday the 14th for clean, fun waves, and the big weekend swells on the 20th and 26th. The 20th is the one for the brave souls.
Rusty out.
