Table - best surf conditions forecast for Zaga (Koroni) over the next 16 days.
Alright folks, Rusty here. I’ve had a good look at the charts for the next 16 days, and I’ll be honest with you—it’s a pretty grim outlook for the Zaga (Koroni) area. The long-range models are showing a whole lot of nothing for a long stretch, so let’s break it down.
We’re kicking off on Sunday, July 12th, and there’s just no surf to speak of. The combined wave energy is flat at zero (0) and the swell height is a dash. This pattern of poor surf conditions carries right through the entire first week. The water temp is sitting at 80°, which is a touch warmer than normal for this time of year, so if you’re just looking for a swim, it’s fine, but for waves? Don’t bother.
The first glimmer of anything comes on Sunday, July 19th, in the afternoon. Finally, a tiny pulse of swell shows up: 1 ft from the SW with a period of 5 seconds. That’s short-period, weak windswell, and the combined energy is only 10. That’s barely a ripple. With a moderate cross-offshore breeze from the WSW, it’ll be clean, but the wave quality is still poor. Not enough to get excited about.
After that, we’re back to flat conditions. The entire second week—from Monday, July 20th, right through to Monday, July 27th—shows zero swell, zero energy, and just glassy or light breeze conditions. There’s no surf on offer at all.
Zaga is a beach and point break that’s sheltered and rarely breaks anyway, so a blank run like this isn’t a huge surprise. The optimum swell direction is SSE, but we’re not seeing any proper swell from that direction in the forecast window. For beginners, it doesn’t matter because there’s nothing to ride. For anyone else, if you’re desperate for a paddle on a flat day, the water will be glassy on a few mornings, but that’s as good as it gets.
Bottom line: the 16-day window is a write-off for surf. No standouts, no hope. If you’ve got a kite, the moderate cross-shore winds on some afternoons might be more interesting than a paddle board. Otherwise, wait for the next update—forecasts can change, but right now, it’s a long, flat spell.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Zaga (Koroni) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
