The Lowdown
Alright folks, Rusty here. Let's be straight with you. I've taken a long, hard look at Zaga (Koroni) over the next 16 days, and I gotta tell you, it's a bit of a sad story. The forecast is a flat spell with barely a ripple to get excited about. This is a beach and point setup that's sheltered and rarely breaks, and unfortunately, the next two weeks are proving why.
The water's sitting at a warm 79°, which is pretty much bang on average for this time of year, so at least you won't be cold while you're floating around doing nothing.
Looking at the first few days, Friday the 31st of July is a write-off. We're talking a tiny 0.3ft to 0.9ft of short-period slop with a combined energy of just (1) – that's basically nothing. The wind is messy, bouncing from cross-off to light cross-onshore, but honestly, there's no wave to surf anyway.
The pattern continues through the entire first week and into the second. The swell heights are either a dash (meaning no measurable swell) or a paltry 0.9ft to 1ft. The period is a pathetic 2 to 4 seconds, which is pure wind chop, not a wave you can ride. The combined energy never gets out of the single digits (1). There are a few mornings with glassy, clean conditions, like on Monday the 3rd of August morning, and Tuesday the 4th and Wednesday the 5th with light offshore winds, but it's all for nothing because there's zero swell to work with.
The whole 16-day window is a massive gap. Honestly, there isn't a single standout day. The best you could hope for is a tiny, gutless 0.6ft to 1ft bump on the afternoon of Saturday the 15th of August, but even then, the wind is cross-off and the energy is still (1). It's not surfable.
For a break that's already inconsistent, this is a full-on blank run. It's more normal for this area to have periods like this, and the forecasts can always change, but right now, put the board away. If you're desperate for a paddle, the setup is so weak it might be more interesting for a kite surfer than a paddle surfer, but even then, it's slim pickings.
Rusty signing off.
