The Lowdown
Hey folks, Rusty here. Let’s be straight with you—this outlook for the next 16 days is a tough one. Zaga (Koroni) is a sheltered beach-and-point setup that rarely breaks, and right now it’s showing zero surf energy across the entire forecast period. The combined energy of all swells directed here is a flat 0 (0), meaning there’s simply no swell making it in. We’ve got a long stretch of nothing from Thursday, 20 August all the way through to Friday, 4 September. The water temp is about average for this time of year, so no surprises there.
The winds are often glassy or offshore, especially on the mornings—like Thursday, 20 August morning with calm winds and glassy conditions, or Saturday, 22 August morning with gentle offshore breezes. But with no swell, that clean surface doesn’t mean a thing for surfing. The afternoon winds swing cross-shore or cross-off, but again, it’s a flat ocean.
If you’re a paddle surfer, there’s nothing to chase here. The setup looks more interesting for kite surfing given the consistent cross-off breezes and clean conditions, but for waves? Zilch. This kind of blank run is normal for a break that rarely breaks, so don’t hold your breath. Forecasts can change, but right now, there’s no standout surf on offer.
Rusty.

The above surf forecast table for Zaga (Koroni) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Zaga (Koroni) can be found by selecting the local surf guide option on the grey menu.

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.
