The Lowdown
First up, the outlook for the next couple of weeks...
Honestly, it’s a tough stretch for the Biologia (Mar del Plata) area. We’re looking at a long, dry spell to start. From now until late in the second week, there’s very little to get excited about. The first few days are a complete write-off with zero surfable energy. You’re looking at a gap of nearly a week before we even see a ripple that’s worth paddling for.
The first real whisper of hope comes on Tuesday, September 8th. We get a tiny pulse of swell, around 1 ft from the SE with a 10-second period, but the energy is weak (28). The northwest wind is cross-off, so the surface is clean, but don’t expect much. It’s a beginner-only day, if you’re really desperate.
That little blip fades fast, and then we’re back to flat or very weak, choppy conditions for days. The water temp is sitting at about 51°, which is a touch warmer than normal for this time of year, but you’ll still want a thick wetsuit.
Now, the one moment that stands out. On Saturday, September 12th, in the afternoon, things get interesting for the wrong reasons. A solid 8 ft SE swell pushes through, with a short 8-second period. The combined energy jumps to 851 – that’s strong energy. But the wind is a nasty cross-onshore from the SSE at 15 mph, making it choppy and messy. This is strictly for experts only. For anyone else, it’s a washing machine. For kite surfers, the setup might be more attractive than for paddle surfing.
The next morning, Sunday, September 13th, is the best we’ve got. The swell drops to a more manageable 4 ft from the ESE, still short period at 8 seconds, but the energy is a moderate 160. The wind is light from the NW, clean and cross-off. It’s surfable, but still very ordinary. This is the only window in the entire 16 days where I’d even bother looking at the water. It’s not a standout, just the best of a bad bunch.
After that, it’s back to nothing. Clean, but flat. The consistency is just not there. This is one of those blank runs that’s more normal for the area. Forecasts can change, but right now, I’d be planning on doing something else.
