The Lowdown
Well, folks, it's Rusty here, and I've gotta be straight with you. We're looking at a 16-day window for Zaga, and honestly, it's a tough one. This spot, a sheltered beach and point break up in Koroni, is a real shy character – it says "rarely breaks" in the notes, and this forecast is proving that out.
The whole 16-day run is a long, flat stretch. We're talking about a solid gap of days with no surf worth paddling for. The first little flicker of energy doesn't show up until Wednesday morning, the 16th of September, and even that’s a whisper at best. From now until then, it’s a big zero.
That first hint on Wednesday morning, the 16th, is tiny. We're looking at a 0.7ft swell from the ESE, with a period of just 3 seconds. That's barely a ripple, and the energy is a pathetic 1. It's glassy, which is pretty, but there's nothing to ride.
We get a minor pulse on Thursday afternoon, the 17th, with the same direction but a slightly bigger 2ft swell. However, the period is still a short 4 seconds, and with onshore winds from the ESE at 9 mph, the conditions are poor. The wave energy is still very weak (18).
The best of a bad bunch, and this is being generous, comes on Friday afternoon, the 18th of September. The swell picks up to 3ft from the SE, with a period of 5 seconds, giving us a combined energy of 37 – still very low. The wind is light and variable, but it's onshore, so it's not ideal.
A couple of mornings have glassy conditions, like Saturday, the 19th, and again on Saturday, the 26th, but the swell is either tiny or non-existent. There's just no power behind it.
For the whole 16 days, the surf is consistently rated as "poor." There are no standouts, no hidden gems. This is a blank run, and for a spot that rarely breaks, it's a normal part of life here. Honestly, the setup looks more interesting for a paddle on a stand-up board than for a surfboard.
Keep your eyes on the charts, but for now, it's a waiting game.
Rusty.
