The Lowdown
Alright folks, Rusty here. Let's be straight with you: the outlook for Zaga (Koroni) over the next 16 days is a tough one. There are zero good surf options in the whole window. The file shows nothing but "poor surf conditions" for every single time slot across the entire forecast, right the way through to 28 September. There’s a big gap from now with no real surf to speak of, and it doesn't improve at any point.
We get a little tease on the morning of Thursday the 24th. The combined wave energy hits a moderate 122, with a 4ft swell rolling in from the SSE. That’s the biggest number we see, and with a 7-second period it’s a short-period windswell, not a clean groundswell. The problem is the wind: it’s a cross-onshore breeze that afternoon, chopping things up. The morning before that is cleaner, with a moderate 83 energy reading and a 3ft SSE swell, but even then, it’s still rated as poor surf. The water temp is a notable 84° at times, which is much warmer than normal for this time of year.
The only real highlight, if you can call it that, is a brief moment on the morning of the 25th. The wind goes completely glassy, calm as can be. But the swell is only 1ft from the SSE with a weak energy reading of 15. It’s tiny and inconsistent, and Zaga is a spot that rarely breaks. This setup looks far more interesting for a kite surfer than a paddle surfer. For the rest of the fortnight, we’re looking at flat spells or tiny, messy waves with poor winds. The consistency just isn’t there, and unfortunately, for this area, a blank run like this is more normal than not. Forecasts can always change, but right now, leave the boards at home.

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.
