Biologia (Mar del Plata) Surf Forecast and Surf Report

Alright, surf’s up... well, barely. Let’s be straight with you. The next week and a half is gonna be a whole lot of nothing, with a couple of windows that might get you wet if you’re desperate. The ocean’s just flat and messy for the most part, with the wind all over the shop. It’s one of those stretches where you gotta be patient.

We’re kicking off on Wednesday the 5th at Biologia (Mar del Plata). It’s a point break, very consistent, and it’s a touch warmer than normal in the water at 50°. That little bump in temps is nice, but the surf is pretty ordinary. There’s a weak 2ft SE swell with a period of 9 seconds, and the energy is weak at 70. It’s glassy, which is the only saving grace. You’ll get a wave, but it won’t be a memory-maker.

Then Thursday and Friday are write-offs. The wind gets up, the swell gets jumbled, and the energy just drops off a cliff. Friday afternoon sees a tiny 0.3ft wave with almost no energy at all, but the wind is offshore, so it’s clean. Still, there’s just nothing to ride. That flat spell hangs around right through the weekend and into the start of next week. Monday the 10th has some lumpy cross-chop, but the swell is still poor. It’s not until Tuesday the 11th that we see a pulse of energy, but it’s still not rideable with any quality. It’s a frustrating trend.

Now, here’s the long game. A solid week from now, on Tuesday the 18th of August, things are looking like they *might* fire. The morning shows a 7ft ESE groundswell with a 10-second period, and the energy is strong at 1030. The wind is light offshore, so it should be clean. This is for experienced surfers only—this is getting big. The afternoon swells to a massive 10ft from the SE with a period of 10 seconds, and the energy jumps to a very strong 3453. But here’s the catch: the notes say it’s predicted to be too big for this break. It’s gonna be a washing machine. So, if you’re a charger, the morning might be your window. But if you’re not, this one’s for the spectators.

After that, Thursday the 20th sees the swell drop back down to 3-4ft with a longer 11-second period from the ESE. The energy is moderate at 294, but the wind is cross-offshore, keeping it clean. It’s marginal, a bit of a lottery, but there could be a few fun ones for someone who knows the break.

So, there you have it. A long dry spell, then one morning of serious size, and maybe a salvageable session after that. Don’t hold your breath, but don’t put the board away either. Forecasts can change. Keep an eye on that Tuesday the 18th.

Rusty.
