The Lowdown
Alright crew, Rusty here, and I’ve gotta level with you – it’s gonna be a quiet one for a while. We’re looking at Zaga (Koroni), and the 16-day window starts off with a whole lot of nothing. You’re looking at a gap that stretches all the way from Wednesday the 16th of September through to Monday the 28th of September. That’s a long stretch of flatness, so don’t bother checking the beach until then.
Now, come Monday morning the 28th of September, things finally wake up. There’s a pulse of swell pushing in from the southwest at 4ft, with a period of 6 seconds. The combined energy hits that moderate mark at 105, so there’s some juice there, but don’t get too excited. It’s a short period windswell, so it’ll be a bit choppy and disorganised, especially since the wind is a moderate cross-shore out of the NE. The sets will be messy. This setup is honestly more interesting for kite surfing than a proper paddle session.
Into Monday afternoon, the swell drops back to 3ft from the SSE, period hanging at 5 seconds, and energy drops to 65. The wind goes lighter and cross-offshore from the NNW, which cleans it up a bit. It’s still tiny and weak though, better for a longboard cruise than anything else.
Tuesday the 29th and Wednesday the 30th keep fading, with knee-high dribbles from the SSE and clean conditions. The water temperature anomaly isn’t mentioned in the data for this spot, so I’d say it’s pretty average for the time of year.
Honestly, there’s no standout here. The whole 16-day block is a bust for surf. A blank run like this is more normal for this sheltered setup.
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.
