The Lowdown
Alright, let’s shift to feet and miles. This is Rusty, and here’s the straight talk on the surf.
We’re looking at a long, quiet spell. The first real hope for a wave doesn’t pop up until early August, and it’s a small window. Before that, it’s a lot of tiny, weak swell and bad wind. You’ll be watching the ocean do nothing for days on end.
The best spot to keep an eye on is Biologia (Mar del Plata) . It’s a consistent point break. The water temp here is 50°F, which is a touch warmer than usual for winter.
The only time the stars line up even a little bit is Sunday, August 2nd. The morning session is the pick of the litter. The wind will be a light offshore from the SW at 6 mph, making the surface glassy. The swell is a small 2ft coming from the E with a 10-second period. The combined energy is a weak 69, so it’s small and soft. The crowd-meter says “sometimes,” so don’t expect to have the place to yourself.
After that little window, the rest of the forecast is pretty grim. We get a lot of strong, onshore wind and tiny, short-period slop. The combined energy numbers drop into the lower double digits. It’s just not happening.
So, to sum it up: the only real standout is that Sunday morning (August 2nd) at Biologia. It’s not a classic day, but it’s the one clean, offshore chance in a very long, flat run. Everything else is a pass.
Rusty.
