The Lowdown
Right, I’ve taken a good look at the charts for Zaga (Koroni) over the next couple weeks, and I’ve got to be straight with you – it’s looking like a proper flat spell. We’re staring down the barrel of a long, quiet run here. The forecast is pointing to a solid 16-day period with surf so small or non-existent it’s a write-off for any kind of proper paddle session. There are a few tiny ripples on the horizon around September 4th and again on the 9th, but we’re talking ankle-snatchers. The wave energy is barely registering a pulse – we’re looking at combined energy values of 1, 3, or 5 for those faint blips, which is nothing to get excited about.
It’s a sheltered setup here, and this spot rarely breaks, so a blank run like this isn’t totally out of character for the area. That said, the water is much warmer than normal for this time of year, sitting around 82° – a real anomaly. Conditions will be clean and glassy on many mornings with light NNW or offshore breezes, but without any swell to work with, it’s just a pretty lake.
The only time the ocean shows any sign of life is on Friday afternoon, September 4th, when a tiny 1.0-ft swell from the SW with a period of 2 seconds tries to push in, but it’s crossed up by a moderate cross-offshore breeze. That’s barely a ripple. On the morning of September 9th, we get a whisper of a 0.3-ft swell from the SE with a 4-second period and dead calm glass, but again, it’s not surfable. The 13th of September offers the biggest bump of the whole run – a 1-ft swell from the SW with a 4-second period and clean wind – but it’s still flat by any standard. For a beach and point break setup with no wave energy, this is looking more like a kiters’ day than a surfers’ day if the wind has any puff.
Honestly pals, there’s nothing to recommend. Put the boards away for a bit, forecasts can change, but right now it’s a total bust.

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.
