The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next 16 days.
To be straight with you, if you’re looking for a proper surf, you’re in for a long wait. The first 13 days are a total write-off. From Sunday the 23rd of August all the way through to Friday the 4th of September, there’s simply no swell to speak of at Zaga. The combined energy is sitting at zero (0) the whole time. It’s flat, mate. You’ll see some glassy mornings early on, like the 27th and 28th, and even a few offshore breezes, but without any waves, it’s just a pretty lake. That’s a solid 13-day gap with nothing to ride.
The first sign of life shows up on Saturday the 5th of September. The morning brings a tiny 0.3ft ripple from the southeast with a period of 4 seconds, and the combined energy is a weak 1. It’s glassy, but you’re basically paddling for ripples. The afternoon is a little more promising with a 1ft swell from the south, though the period drops to 3 seconds. The wind is cross-off from the west at 15 mph, so it’ll be clean, but the waves are just too small and weak to bother with. The energy is still only 2.
Sunday the 6th of September looks like a complete non-starter again. A fresh offshore breeze from the NNW at 19 mph in the morning will keep the water glassy, but the swell is gone again. The afternoon is clean with a cross-off, but the combined energy is a flat zero.
So, the honest truth is there is no standout session here. The only break on offer, Zaga (Koroni), is a sheltered beach-and-point that rarely breaks, and this forecast proves it. Even when that tiny pulse shows up on the 5th, it’s too small and weak for any real surfing. For a beginner, the 1ft on the 5th afternoon might be a fun paddle, but for anyone looking for a real wave, you’re better off waiting for the next forecast.
Stay patient, lads. The flat spells here are normal for this setup.
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.
