The Lowdown
Well, folks, Rusty here. I gotta be straight with you – this 16-day window for Zaga (Koroni) is a total dud. There's absolutely no swell on the cards. Not a single ripple. The combined energy is zero every day, and the wave comment is "poor surf conditions" all the way through to the 2nd of August.
Now, I know that sounds grim, but don't chuck your board in the bin just yet. Zaga is a spot that "rarely breaks" – it's a sheltered beach and point setup that needs a very specific SSE swell to get going. So a blank run like this is actually pretty normal for the area. It's not a sign of a bad season, just the way this place goes.
The wind, ironically, is often clean. We've got glassy mornings on the 19th, 20th, 21st, 24th, 30th, and 31st July, and plenty of offshore or cross-offshore breezes on other days. But with zero swell, it's just a mirror-flat lake. Even the strongest offshore winds (like 25 mph on the 26th July afternoon) can't make anything of it.
The forecast is consistent – no waves. So save the petrol, leave the wax at home, and maybe go for a swim instead. If you're desperate for a paddle, you might find a tiny bump on a freak day, but honestly, don't hold your breath. Forecasts can change, but right now there's nothing to get excited about.
Stay salty,
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.
