The Lowdown
Righto, grab a seat. Rusty here.
First up, let’s be straight with you. For Zaga (Koroni), we’re looking at a real quiet spell. The finder’s showing nothing but zeros for the next sixteen days. There’s a total gap right from the get-go. The first record kicks off on Wednesday the 29th of July and from there, it’s a long, flat run all the way through to at least Thursday the 13th of August. You won’t be paddling out for any proper waves in that time.
The guidance confirms it: Zaga is a spot that "rarely breaks." So this blank run isn’t a surprise; it’s more normal for this area. The water temp is about average for the time of year, so no weird anomalies to report. The winds are often clean or glassy, but without any swell, that’s just a nice day at the beach, not a surf session.
The combined energy of all swells directed here is zero (0) across the board. Even the few times we see a tiny 0.3ft SE swell with a short 4-second period, it’s too weak and the wave comment is "poor surf conditions." That kind of tiny, short-period chop is barely worth mentioning.
Stick a pin in it. The surf is flat, and it tends to stay that way here. Forecasts can change, but for now, there’s nothing to chase.

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.
