Zaga (Koroni) surf forecast from 30 Aug 2026:
Best Forecast Surf Conditions for Zaga (Koroni) this week:
The largest open ocean swell (not directed at the beach) is 0.8m 4s period and expected on Sunday (Sep 06) at 3PM.
The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty flat for the Zaga zone.
Looking at the whole 16-day window, there’s just no proper surf to get excited about. The swell energy is basically non-existent, sitting at zero most days, and when we do get a tiny bump, it’s pathetic – we’re talking 0.3ft to 1ft at best. The water is warm though, sitting at 83°F, which is much warmer than normal for this time of year, so if you just want a float, it’s lovely. But for waves? Nope.
The first recommendation doesn’t even show up until the 7th of September, and even then it’s a joke. Monday morning the 7th of September brings a tiny 0.7ft swell from the ENE with a period of just 2 seconds – that’s pure wind chop, not a wave you can ride. The combined energy is a measly 1 (one). Winds are light and clean, but there’s nothing to surf. That afternoon? Even smaller at 0.3ft from the SE.
We get a few more of these micro bumps through the second week, but they’re all the same story: 0.3ft to 1ft, short period, and combined energy never getting above 10 (ten). The 13th of September Sunday morning is the best of a bad lot, with 1ft from the ESE at 5 seconds, and glassy conditions. But honestly, that’s an ankle-snapper. The break is a beach and point setup that rarely breaks anyway, so this blank run is pretty much normal for the area. No standouts here, just a long stretch of flatness.
On the bright side, the wind is often light or offshore, so the bay will be smooth. But if you’re looking to paddle, you’re out of luck. If the wind picks up, it might be a better day for a kite, but for surfing, leave the board at home.
Rusty.
