Biologia (Mar del Plata) Surf Forecast and Surf Report

Alright, let’s have a look at what’s on offer for the Mar del Plata stretch.

Honestly, it’s a pretty grim run for the next couple of weeks. You’re looking at a long stretch of small, weak, and messy conditions. The first real chance of anything half-decent is a long way off, and even then it’s nothing to shout about.

The starting point is Biologia (Mar del Plata) on Friday morning, August 28th. We’ve got a tiny 2ft easterly swell with a 9-second period, and the combined energy is a weak 133. The water is a touch warmer than normal at 50°, which is about 3° warmer than average for this time of year. The wind is a light offshore from the WNW, so conditions will be clean. It’s surfable, but it’s very ordinary. This is a beginner-friendly point break that’s very consistent, but it’s also exposed, so any swell gets in. Crowds are possible here.

From Saturday morning the 29th, the swell drops even further. By Saturday afternoon, we’re down to 2ft from the east with a 10-second period, energy is a paltry 52, and winds go cross-shore. The rest of that weekend and through the entire first week of September is a write-off. Swell heights sit between 0.3ft and 2ft, periods are short, and the combined energy rarely cracks three digits. The wind is either cross or cross-off, so even if there was a pulse, it wouldn’t be clean for long. It’s a lot of poor surf conditions.

We finally see a pulse of energy on Wednesday morning, September 9th, with a 3ft southeasterly swell coming in at 10 seconds. The combined energy hits 152, which is moderate, but it’s completely ruined by a moderate cross-shore wind. The conditions are described as poor, and the score reflects that. This pattern of moderate energy with cross winds continues through the 10th and into the 11th.

The 11th of September has the biggest energy of the whole forecast. Friday morning has a 3ft southeast swell with a 9-second period, and energy jumps to 265. But the wind is a moderate cross-shore from the northeast, so it’s messy. By Friday afternoon, the swell period stretches to 12 seconds, energy climbs to 342, and the swell height is 3ft. That’s a good-looking groundswell pulse, but again, the wind is a fresh cross-shore, creating lumpy, choppy conditions. It’s a real tease.

Then we get to Saturday, September 12th. The morning shows a 3ft southeast swell at 11 seconds, with a moderate cross-offshore wind from the WSW. That’s the cleanest window we’ve seen in a long time. The energy is a solid 285, and the conditions are described as clean. This is the best bet in the entire 16-day window. It’s still a small swell, but the period is decent, and the wind will give you some clean faces. The afternoon, however, turns into a 5ft easterly wind swell with a terrible 6-second period, and while the wind is cross-off, that short period will make it bumpy and hopeless.

So, to be honest, if you’re looking for a standout, hold out for Saturday morning, September 12th, at Biologia. It’s not perfect, but it’s the only time the wind and swell align. Everything else is a long, flat, or blown-out wait.
