Biologia (Mar del Plata) Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s happening around Mar del Plata.

Honestly, I’m not gonna lie to you, it’s been a tough stretch and it stays pretty quiet for a while. The first real chance to get wet comes on Friday morning, July 3rd, but even then it’s only small, weak stuff pushing 2ft from the SE. The water is a touch warmer than normal for this time of year at 51°, but don’t get too excited about that because there’s hardly any energy in the ocean.

The forecast period starts with a long gap of really poor surf. From now through Thursday, July 2nd, you’re looking at tiny, weak waves. The trough of the week comes Saturday the 4th with glassy conditions in the morning under clear skies but only 2ft from the ESE at a short 6 seconds – barely a ripple. The wind is glass that morning which is a beautiful thing, but there’s just nothing behind it.

We finally see a pulse of moderate energy on Sunday, July 5th – combined energy hits 154 (moderate) and 173 in the afternoon – but the swell is still disappointing at 3ft from the ESE with a 10-second period. It’s cross-onshore, so you’ll be dealing with light wind ripples. Not terrible, but not something you’d paddle across town for.

Things get a little more interesting around Monday, July 13th. The Monday morning session at Biologia should actually deliver some decent conditions. We’ve got a clean 4ft swell from the E, with a 10-second period, and a gentle cross-offshore breeze from the NNW. The combined energy is a solid 290 (moderate). This is the best-looking window in the whole run – clean, manageable size, and the water is still a touch warmer than average. The swell direction from the east isn’t the optimum NE that Biologia really loves, but it’s close enough to work.

If you can hold out until Thursday, July 16th, the afternoon looks promising at Biologia (Mar del Plata). The swell builds to 4ft from the ESE with a solid 12-second period, and we get offshore winds from the west. Combined energy is 400 (moderate-strong). That’s a proper groundswell, and for a point break like Biologia, the longer period is a real plus – the waves will have more shape and punch. Crowds are sometimes an issue here, but on a Thursday it might be manageable.

Be aware that Friday, July 17th sees strong offshore winds at 25-28 mph. The swell is 4ft with a long 13-second period, and while it’s clean, those winds make paddling out a real battle. That one’s for experts only.

So the standout window for me? Monday, July 13th in the morning. It might not be epic, but it’s the cleanest, most user-friendly day on offer.
