La Pepita (Mar del Plata) Surf Forecast and Surf Report

Alright, this is Rusty, and I’m lookin’ straight at the charts for La Pepita (Mar del Plata). It’s a beach and jetty setup, exposed to the swell, and we’ve got a pretty quiet run ahead with a couple of bright spots buried in the second week.

Right now, the water temp is pretty average for the time of year, nothing wild going on there.

We are in a bit of a dry spell to kick things off. Don’t bother paddling out Monday the 7th or Tuesday the 8th – the swell is tiny and the wind’s just cross-off, making for marginal, unexciting waves. Wednesday the 9th and Thursday the 10th are a write-off too, with poor swell energy and mostly poor surf conditions. The combined energy is barely cracking 55 to 175 (weak to moderate), and it’s just not doing anything.

Friday the 11th looks even uglier – a short period 4 second windswell hits with a strong onshore wind, making a total mess. Then Saturday the 12th brings a big jump in size, but it’s all bad news: 8ft of wind-affected swell with a fresh cross-onshore wind. That’s a lot of water moving, but it’s poor surf conditions – lumpy and choppy. That’s more of a kite session than a paddle session.

Sunday the 13th sees some relief. The wind swings light offshore and the swell drops to a clean 3ft from the S, with a combined energy of 323 (moderate). It’s small but clean, and you might score a few if you’re picky.

Then we hit the real standout window. You have to circle Wednesday the 16th and Thursday the 17th of September. This is the highlight.

On Wednesday the 16th, the morning is already looking promising: an offshore 25 mph wind, clean conditions, and a 7ft SSW swell. The combined energy jumps to 1008 (strong). The afternoon gets even better with a moderate offshore wind and a solid 6ft S swell, combined energy of 649. That’s going to produce some real, rideable waves.

But the true star is Thursday the 17th. The morning has a 8ft S groundswell with a long period of 13 seconds, and the combined energy is a beastly 1890 (very strong), with a clean cross-off wind. The afternoon steps it up even more: 8ft from the SSE, a very long period of 14 seconds, combined energy of 2397 (very strong). This is excellent surf for experienced surfers. That long period will wrap in nicely at the jetty, giving some proper shape and power. The wind stays gentle and clean.

Friday the 18th is still surfable but dropping, and after that, from Saturday the 19th through to the end of the period (Tuesday the 22nd), it fades right back to poor, small conditions with no energy to speak of. That’s about a four-day blank run to close things out.

So to sum it up: hold tight through the first week, and don’t get excited until Wednesday the 16th. The absolute standout is Thursday the 17th – that 8ft, 14-second SSE groundswell with clean winds will be the one to remember. The jetty could be on fire for the crew who know it.
