The Lowdown
G’day, this is Rusty.
Let me be honest—there’s not much happening at Zaga (Koroni) over the next 16 days. The surf forecast is pretty much flat from now until the end of the period. The first hint of any swell doesn’t show up until the afternoon of Friday, September 4th, and even then it’s just a tiny 0.3m from the SSW with a period of 2 seconds. The combined energy is only 1, so it’s barely a ripple. The water is sitting at a warm 82°, which is much warmer than usual for this time of year, so at least the water temp is a standout.
The spot itself is a beach and point setup, sheltered, and it rarely breaks at the best of times. It’s a beginner-friendly wave when it’s on, but it’s just not happening here. We’ve got a long gap of no real surf until the 7th of September Monday afternoon, when a tiny 0.6m from the ESE with a 5-second period creeps in, giving a combined energy of 22—still weak and not worth paddling out for. There is another tiny pulse of 0.6m from the SW on the 13th of September Sunday afternoon, but again, short period and low energy.
The winds are often clean or glassy through the mornings, especially early September, but without any swell, it’s just a flat lake. The best conditions for any wave would be those glassy mornings with light offshore winds, but there’s simply nothing to ride. If you’re a kite surfer, the stronger afternoon cross-off winds might be of interest, but for paddle surfing, it’s a write-off for the entire 16-day window.
Honestly, it’s a rare blank run for this area, but it happens. Forecasts can change, so keep an eye out, but right now, leave the board at home.
