The Lowdown
Alright, I’m Rusty, and here’s the outlook for Biologia (Mar del Plata).
Look, I’m gonna be straight with you — the next couple of weeks are pretty flat and frustrating for us here at Biologia. This is a very consistent point break, but right now we’re in a dry spell. The water’s sitting at 51°F, which is 4°F warmer than average for this time of year — that’s notable, a bit of a warm patch for late winter.
The first real hope doesn’t show up until Tuesday morning, September 15th. That morning, we’ve got a clean 4ft swell from the east with a nice long period of 11 seconds, and combined wave energy is moderate at 363. The wind is offshore from the west at 12 mph, so it’s going to be glassy and clean. This is the standout of the whole outlook — best conditions on offer. That afternoon, the wind picks up to a strong 22 mph from the southwest, which will mess things up, but the morning session is the one.
Before that, we’ve got over a week of tiny surf and poor conditions. The swell barely gets above 2ft until the 6th of September, when Sunday afternoon sees a sudden jump to 6ft from the ESE, but the wind is cross-onshore and lumpy, so it’s not really surfable. The energy peaks at 553, but it’s messy.
From the 7th through the 14th, it’s mostly small, weak, and onshore or cross-shore. A few mornings like the 11th and 12th offer clean conditions with offshore winds, but the swell is only 2ft to 3ft with short periods around 8-10 seconds — surfable but very ordinary. The 12th Saturday afternoon has offshore wind and a little energy at 109, but again, small.
So, if you’re keen, pencil in the morning of Tuesday, September 15th. That’s your best shot. The rest is a waiting game.
