Alright, Rusty here. Let’s break down what’s heading our way for the next couple of weeks.
Honestly, the surf over the next week is pretty flat and messy overall. For the most part, we're looking at weak, short-period swells. The water temp is currently sitting at a touch over 51°F, which is a degree or so warmer than normal for this time of year, so it’s not too bad.
We get a bit of a run from Tuesday, July 7th through to Monday July 13th. It’s not going to be epic, but there are a few windows worth a paddle. The best bet in this stretch looks to be Tuesday afternoon, July 7th. At Biologia (Mar del Plata), we’ll see a 4ft swell coming out of the SE with moderate offshore winds from the NW. The combined energy is moderate at best (206) but the offshore wind should keep the surface clean. It’s a point break that's very consistent, so there will be waves coming through. This spot faces NE and is best with NE swell, so while the direction isn’t perfect, the clean conditions are the main draw. Usually you’ll have some company here, so expect a few others in the water.
Then there’s a possible standout on Saturday July 11th. Again at Biologia, the guidance points to a period of good surf conditions. The morning shows a 3ft SE swell with a longer period of 11 seconds, paired with light cross-offshore winds from the N. The energy jumps to 271, which is a decent kick. It’s consistent and the wind will make for clean waves. Just keep in mind, this is more than a week out, so it’s promising but not locked in.
After that, Sunday July 12th still has some energy (up to 310) and a long period of 13 seconds, but the rating dips—marginal tide or conditions might make it a bit tricky. With that long period swell and it being a beach/point mix, the waves might be a bit straight and harder to line up, but it's still worth a look if the tide lines up.
After July 13th, the surf drops right back off, and we’re into a long gap with nothing really worthwhile. The energy is weak and the wind is messy out of the south and west. From about July 18th, the combined energy is almost zero, so it’ll be a flat spell for sure.
So to sum it up: get in the water Tuesday July 7th afternoon for some clean, small waves, and keep an eye on Saturday July 11th for the best combo of size and conditions in the forecast.
