The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for Zaga (Koroni) is a tough one to write. We’re looking at a full 16-day window, and I’m not seeing a single moment where the surf comes together for a decent paddle. The swell energy is flat, zero (0) on the combined energy scale for the entire period. The water is a touch warmer than normal, sitting at 80°, but that’s cold comfort when there’s nothing to ride.
From the 13th of July right through to the 28th of July, the forecast is a complete bust for waves. The swell height is consistently a dash, meaning no measurable surf. You’ll get some glassy mornings – like the 14th, 15th, 16th, and 17th – and even a few offshore wind days later on, from the 22nd to the 24th, with winds gusting up to 25 mph. But without any swell, that offshore wind is just blowing over flat water. It’s a classic case of the wind being right but the ocean being totally asleep.
The only blip of a wave comes on the afternoon of the 18th, with a tiny 1 ft, 2-second period SW swell. That’s weak and short period (2 seconds) – it’ll be a dribble, not a wave, and it’s coming right onshore and choppy. Honestly, not worth getting wet for.
Zaga is a sheltered, rarely-breaking beach and point setup that’s best for beginners, but it’s totally dry here. With no swell and a few days of strong cross-off or offshore winds, the setup would actually look more interesting for kite surfing than paddle surfing – you’d get clean, flat water to ride on, but nothing to surf. For a spot that’s already inconsistent, a blank run like this is more normal. We just have to wait for the next weather system to kick some life back into it.
Rusty.
