The Lowdown
Hey, Rusty here.
Let’s call it like it is – this stretch is a total dud. From now through the 5th of September, Zaga (Koroni) is flat as a pancake. No real surf to speak of.
Starting Friday the 21st of August, there’s nothing – zero combined swell energy (0). That pretty much sums up the whole run. The water’s at 83°, which is much warmer than usual, a notable 2° above the norm, but it doesn’t put a wave in the water.
You get some glassy mornings, like Tuesday the 25th and Wednesday the 26th, with no wind, and Thursday the 27th morning is dead calm – but still no swell. The only tiny blip is late Thursday the 27th afternoon, when a 0.3ft SW swell creeps in with a 2-second period, combined energy of 1. That’s barely a ripple, and the wind is cross-offshore at 15 mph, so it’s poor.
Then again on Saturday the 5th of September afternoon, there’s a 0.3ft SW swell at 5 seconds – combined energy of 1 – but it’s nothing to paddle for.
This spot is a beach and point, good for beginners when it works, but it rarely breaks. Crowds can show up sometimes, but not this time.
The upside? Loads of clean, offshore and glassy conditions, so if a swell ever appears, it’ll be perfect. But for now, we’ve got a 16-day dry spell. Forecasts can change, so don’t write it off completely, but today it’s a flat-out bust.
Rusty.

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.
