The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Zaga (Koroni). I gotta be straight with you – this is a tough one. The whole 16-day window is a blank. Not a single decent wave on offer. That's right, from now through the 12th of September, every single session is flagged as "poor surf conditions." There's simply no swell energy to speak of.
The water is a balmy 84°, which is a good 5° warmer than usual for this time of year. That's very unusual, but it doesn't do us any good without waves.
We've got plenty of glassy mornings and clean offshore breezes, especially from the NW, but with zero swell, it's just a flat, pretty lake. The setup here is a sheltered beach and point, which normally needs a decent SSE swell to work. Since that's not happening, and the few tiny bumps we see are from the wrong direction, the whole report is a write-off.
For a spot that rarely breaks, a long run of flatness like this is more normal than not. It's a tough stretch, but keep an eye on the charts – it tends not to stay this way forever.
Rusty.

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.
