The Lowdown
G’day, Rusty here. Well, I’ve had a good look at what’s on the cards for Zaga over the next couple of weeks, and I gotta be straight with you—it’s a long, flat run. There’s simply no swell to speak of for the entire 16-day window. Zaga (Koroni) is a sheltered little nook that rarely breaks, and this forecast backs that up. We’re looking at a solid gap from now through to August 10th with no surf to recommend. The water’s sitting at a very warm 82°F, which is much warmer than usual for this time of year—about 4°F above average, so you can leave the thick rubber at home.
We do see a few tiny pulses of 1ft swell from the SW on a few afternoons, but with a period of only 2 seconds, that’s just wind chop, not proper waves. The combined energy is basically zero (0 to 1), so there’s nothing for your board to work with. Mornings often glass off with light offshore or glassy conditions, which is a real tease—clean water but no waves. Even a rare spot like this one isn’t going to fire without a solid groundswell from the SSE direction it needs.
To be honest, this stretch looks more suited for a long swim or a paddleboard cruise than catching any real waves. For a place that’s already inconsistent, a blank run like this isn’t unusual for the time of year. Stay patient, keep an eye on the charts, and hopefully something changes further down the line. Rusty out.

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.
