Biologia (Mar del Plata) Surf Forecast and Surf Report

Alright, Rusty here. Let’s get straight into it.

Right off the bat, I gotta be honest with you – this is a lean stretch for Biologia (Mar del Plata). We’re looking at a solid 16-day window, but there’s a real dry spell to start. The first usable surf doesn’t show up until Friday morning, July 17th, and even then it’s barely a whisper. The water’s sitting at 50°, which is a touch warmer than normal for this time of year – not a game changer, but a little comfort.

That Friday morning, July 17th, is the only real standout in the whole run. We’ve got a tiny 3 ft swell from the ENE, period of 8 seconds, and the combined energy is weak at 94. But here’s the thing: the wind is light and cross-off from the north at 3 mph, leaving the surface clean. For a beginner-friendly point break that’s very consistent, this is your best shot. The swell direction is ENE, which isn’t the optimum NE the spot loves, but with offshore wind and tiny waves, it’s still rideable and tidy. Crowds are possible here – it’s a beginner spot that gets busy sometimes.

After that, it’s pretty grim. Friday afternoon turns poor with a cross breeze and light rain. Saturday, July 18th, through to the end of the month, the conditions are mostly messy – cross-on winds, choppy water, and tiny swell that never breaks 3 ft. There’s a stretch from Saturday morning to Monday, July 27th, where the score is consistently zero. The swell energy drops into the teens and single digits, and the wind is often onshore or strong. Not worth paddling out.

Late in the run, things get interesting on Saturday, August 1st. We see a jump in energy to 111 (moderate) early and 130 (moderate) in the afternoon, with a swell from the ESE at 1 ft to 2 ft and a long period of 14 seconds. That’s a groundswell, but it’s tiny. The wind is fresh and cross-off in the morning, turning strong cross-shore by afternoon. The long period means the waves will be lined up and have some push, but the size is so small it’s barely a session. For a beach-and-reef setup like this, long period can make it break too straight, so it’s more of a novelty.

Bottom line: Friday morning, July 17th, is the pick of a very quiet bunch. After that, you’re waiting two weeks for a pulse that’s all promise and no power. If you’re desperate for a paddle, that Friday is your window. Otherwise, it’s a long wait.

Rusty.
