The Lowdown
Hey crew, Rusty here taking a look at Biologia (Mar del Plata). This point break is real consistent and good for beginners, but the next couple of weeks are testing our patience. Water temp Tuesday 14 July is 50°, a touch warmer than average – so you won’t freeze your toes off.
For the first week, from Tuesday 14 July through Monday 20 July, it’s all poor conditions. Tuesday morning the 14th showed 3ft of ESE swell (period 10s) with a fresh NNW cross‑off at 19 mph, combined energy just 125 (weak). Nothing happening.
Monday 20 July afternoon throws up a 7ft SE swell but it’s hammered by a 25 mph onshore wind, period only 6 seconds – energy shoots to 431 (moderate) but it’s ugly out there. That’s more kite‑surfing territory.
The one clear standout is Wednesday 22 July morning. We’ve got 6ft of SE swell, 10‑second period, a light offshore wind from the NW at 6 mph, and glassy clean conditions. Combined energy hits 743 (strong). A point break handles this long‑period groundswell well, and with offshore wind the waves should be clean and lined up. Crowds are possible when it’s good, so get there early. The swell direction (SE) isn’t the optimum NE, but the quality still looks top‑notch.
The rest of that week has only marginal moments – Wednesday afternoon turns choppy with 5ft and a cross breeze, Thursday 23 morning drops to 3ft and cross‑shore – not worth chasing. By the weekend of 26–27 July it’s back to small, weak swells and onshore breezes. The final days, Monday 28 and Tuesday 29 July, fizzle to 1–2ft with no energy.
So you’ve got a big dry spell until Wednesday 22 July morning – that’s the only real highlight. After that, mostly mediocre. But Biologia is usually so consistent that this lull feels unusual; forecasts can shift, so keep your eye on that Wednesday.
