The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this 16-day outlook for Zaga (Koroni) is a tough one. There’s a long, dry gap right at the start. From today, the 20th of July, all the way through to the 2nd of August, there is absolutely no surf to speak of. The combined swell energy is sitting at zero (0) the whole time, and the wave comment is "poor surf conditions" for every single session. That’s a solid two weeks of flatness.
The first real sign of life doesn’t show up until Monday the 3rd of August. Monday morning, we get a tiny pulse of swell from the southeast at 0.3 ft, with a period of 4 seconds. That’s a weak, short-period windswell, and the combined energy is a measly 1 (1). It’s glassy though, with a light north-northwest wind. That afternoon, the swell bumps up to 0.7 ft from the south-southwest, but the period drops to 2 seconds and the wind swings to a moderate cross-shore from the southwest, making it choppy. Still, the combined energy is only 1 (1). It’s not surfable for anyone who wants a proper ride. Tuesday the 4th of August morning goes back to flat with glassy conditions again.
This break is a sheltered beach and point setup that rarely breaks. It’s rated for beginners, but with no swell, it’s just a nice spot for a swim. Given the lack of consistent wave energy, this is honestly more of a kiteboarding spot if the wind picks up, but for paddle surfing, there’s nothing to get excited about. The forecast can always change, but for now, it’s a blank run that’s pretty normal for this area.
Keep your eyes on the charts, but don’t hold your breath.
Rusty.

Information about the Zaga (Koroni) Surf forecast
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. Our Zaga (Koroni) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Zaga (Koroni)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
