The Lowdown
Alright, Rusty here again, and I’m telling you, it’s been a lean stretch for waves around here. Across the full 16 days, there’s not one real standout session where everything clicks. We’re looking at a long, quiet period, with the first barely-rideable wave not showing up until around Saturday, August 15th, and even that’s a struggle.
Our only break is Biologia (Mar del Plata), a point that’s usually very consistent, but this time it’s just not happening. Days of flat, poor surf right out of the gate. The water is sitting at 51°F, which is a touch warmer than normal for the season, but that doesn’t do much for the surf.
The first little pulse of energy hits Saturday morning the 15th. We’re looking at a swell of about 4ft from the ENE, with a short, weak period of 6 seconds. Combined energy is moderate, around 145. The wind is cross-shore from the NNE at 9 mph, so it’ll be a bit bumpy. It’s a marginal option for a beginner-friendly wave, but the short period and onshore chop won’t help.
After that, it’s back to tiny, weak swell and mostly onshore breezes. There’s a clean window on Monday the 17th morning when a strong cross-offshore wind from the SW at 19 mph cleans the surface up, but the swell is a tiny 2ft from the east with a 9-second period. Energy is moderate at 117, but the size is just too small to get excited about.
The rest of the two weeks is a washout. Small pulses of 1ft to 2ft swell with poor conditions. The period stretches out a bit around Friday the 21st, with a 12-second SE groundswell, but it’s only 1ft. The wind is clean and cross-off from the NNW, so it’ll look pretty, but you’ll be floating on almost nothing. The combined energy is weak at 23.
Honestly, for the whole 16-day run, there’s no session I’d call a standout. With these tiny, weak swells and frequent onshore winds, the setup here looks more interesting for kite surfing than paddle surfing. We just gotta sit tight and wait for the pattern to shift. Forecasts can change, so keep an eye out, but this is a quiet stretch for Mar del Plata.
Rusty.
