The Lowdown
Alright, folks, Rusty here. Let’s be straight with you—this is a rough one for the Zaga (Koroni) area. The whole 16-day window is pretty much a flat, empty stretch. We’re looking at a long run of nothing from Thursday the 23rd of July all the way through to Wednesday the 5th of August. That’s nearly two weeks of clean, clear skies, but with zero swell to work with. The water is sitting at a warm 82°F, which is much warmer than normal for this time of year, so it’s a lovely temperature for a swim, but not for a surf.
The only real blip on the radar comes on Saturday the 25th of July. The morning shows a tiny pulse of swell from the ESE at 1.0ft, with a period of just 2 seconds. That’s practically a ripple. The combined energy of all swells directed here is barely a whisper at 1. The wind is light and cross-onshore, so it’s not going to be clean. Honestly, that’s barely a wave. Zaga is a sheltered beach and point that rarely breaks, so this is just par for the course. There’s nothing here for a surfer to get excited about.
If you’re desperate for a paddle, the afternoon of the 5th of August shows a tiny bit of life again – a 1.0ft swell from the SSW, period of 3 seconds, and combined energy of 1. The wind is a gentle offshore breeze, so it’ll be clean, but there’s just no power in the water. The whole setup is more interesting for kite surfing than paddle surfing, given the consistent wind and lack of surfable waves.
So, bottom line: don’t waste your time checking the surf for the next couple of weeks. It’s a flat spell, and it’s normal for this area. The forecast can always change, but right now, I’d find something else to do. Keep your eyes on the horizon, but don’t hold your breath.
Rusty.
