The Lowdown
G’day, Rusty here. Look, I’ve had a good long stare at the charts for the Zaga (Koroni) region, and I’ve got to be straight with you—there’s nothing on the cards for the next 16 days. Zero. Nada. The entire run from the 6th of September right through to the 21st of September shows no surfable waves. We’re looking at a flat spell, with the combined energy of any swell directed here sitting at a pathetic 0, and occasionally a tiny 1 or 2 (that’s effectively no energy at all). It’s a long, dry gap for any paddler.
The water temp on the 6th of September was a very unusual 84°, a massive 7° warmer than average for this time of year—that’s seriously warm, almost bath-like. But that’s the only standout, and it doesn’t help for waves.
Zaga itself is a beach and point setup, but it rarely breaks, and this forecast confirms that. The swell is almost nonexistent, with the odd 0.3 ft or 0.7 ft coming from the SE with a short, weak period of 4 to 5 seconds—absolutely no drive. Winds do go glassy at times, particularly on the mornings of the 7th, 8th, 9th, 10th, 11th, and 16th September, but with no swell, it’s just a glassy lake.
Given the complete lack of swell and the sheltered exposure (best from SSE), this stretch is a write-off for surfing. If you’re desperate for a wet session, maybe a longboard and a prayer, but realistically, it’s a blank run. Better luck next time, folks.

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.
