The Lowdown
Alright, this is Rusty.
To be honest, looking at the 16-day window for Zaga (Koroni), we’re in for a tough stretch. The surf is almost non-existent. You’ll be staring at flat, calm conditions for the vast majority of the period. The water is warm, much warmer than usual for this time of year at 82.4°. There’s a long gap here with absolutely nothing to ride.
From now through to the 28th of July, it’s a total write-off. Glassy mornings and clean afternoons, but with zero swell. Good for a swim, not for a surf.
We finally see a tiny pulse on the morning of the 29th of July. The swell hits a meager 0.3 ft from the SW with a period of 6 seconds, giving us a combined energy of just 1. That’s a weak, short-period windswell. The wind is offshore from the NW at 6 mph, so the surface will be clean, but there’s simply no power behind it. This is a beginner-friendly spot that rarely breaks, and this barely qualifies as a wave.
The rest of the forecast through to the 6th of August is more of the same. A few more mornings show a tiny 0.3 ft from the SE, and on the 3rd of August we get a 1.0 ft swell from the SW with a 2-second period – that’s just wind chop. With the consistent cross-offshore winds, the setup might look more interesting for a kite surfer than for someone paddling out.
Honestly, there’s no standout session here. The best you can hope for is a small, clean bump on the morning of the 29th. For everything else, leave the board at home. Forecasts can change, but right now, this is a blank run.
