The Lowdown
Alright, folks, Rusty here. Gotta be straight with you—this next stretch is a tough one. We're looking at a long, long dry spell before anything even thinks about showing up.
Right now, through the 20th of September, it's pretty much flat or close to it. Tiny waves, messy winds, and just no energy. The water temp at Biologia (Mar del Plata) is sittin' at 51°, which is a touch warmer than usual for this time of year, but that's about the only highlight. You're lookin' at a solid week of nada.
Things finally start to stir on Monday the 21st of September. We get a pulse of new swell—5ft from the East with an 8-second period. The combined energy is moderate at 266. It's still a bit raw, but the wind is offshore from the WNW, so it'll be clean. This is your best chance, but it's not a standout by any means. Monday afternoon drops off a bit, but stays clean with offshore wind.
Tuesday the 22nd sees a drop in size to 3ft, but the period stretches to 11 seconds, giving it a bit more push. The energy is moderate at 188, and it's still cross-offshore from the WSW, so it's rideable but not firing.
After that, we're back to the doldrums. The rest of the week and into the next is tiny, with onshore or cross-shore winds. There's a moment of glassy calm on Wednesday the 23rd morning, but with only 1ft on offer, it's more of a lake than a surf. The long period swell (11 seconds) will be breaking straight at this beach setup, so not ideal.
Honestly, if you're desperate, Monday the 21st morning is your only real shot, and even then, it's a gamble. The rest of the 16-day run is a bust. This is one of those times where you're better off waiting for the next system. Keep an eye on it, though—forecasts can change.
Rusty.
