The Lowdown
Alright, folks, Rusty here. Let's be straight with you – this outlook is a tough one to write. I'm looking right down the barrel of the entire 16-day window for our spot, Zaga (Koroni), and there's just nothing doing. Zero. Nada.
The whole forecast period, from Sunday the 23rd of August all the way through to Monday the 7th of September, shows not a single wave of consequence. We’ve got combined swell energy sitting at a flat 0, meaning the ocean is basically a lake out there. The water’s a balmy 83°, which is much warmer than usual for this time of year, but that’s about the only highlight.
We do see plenty of glassy mornings and offshore breezes. In fact, there's a glassy morning on Tuesday the 25th, another on Thursday the 27th, and again on Friday the 28th and Saturday the 29th – all absolutely perfect conditions for surfing if there were any surf. But with no swell, it’s just a pretty, flat sea. Winds are consistently light or moderate from the NNW or N in the mornings, which is exactly what this sheltered spot wants to see, but it just doesn't matter without any energy in the water.
This is a spot that rarely breaks, so a blank run like this isn't entirely out of the ordinary. It’s a dry spell, plain and simple. The forecasts can change, but right now, there are no good surf options anywhere in this 16-day window. I’d suggest keeping the board in the car just in case, but honestly, you're probably better off finding something else to do for a couple of weeks.
Rusty, signing off.

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.
