The Lowdown
Alright, this is Rusty. Let’s cut through it.
I’ve got a 16-day outlook here, and it’s a tough one. There’s a massive gap of nothing at the start. The first several days, from the end of August through the beginning of September, are a flat-out bust. We’re talking glassy mornings and clean offshore breezes, but the ocean is a sheet of glass. No swell, no energy, nothing to ride.
The first hint of anything shows up on the morning of Sunday, September 6th. The wind is clean from the north, cross-offshore, but it’s a tiny bump of south swell. The height is just 1 foot, with a period of 3 seconds, and the combined energy is a measly 1. It’s practically a ripple.
The only break in the mix is Zaga (Koroni), a beach and point that is sheltered and rarely breaks. For a spot that’s inconsistent by nature, seeing a 16-day forecast this flat is a real bummer. It’s a beginner-friendly spot, but it needs a proper swell from the SSE to get going, and that’s just not happening. The water temperature is about normal for this time of year.
So, the bottom line? There’s no standout session. No good waves. The whole 16-day window is a washout. The setup would be more interesting for a kite than a surfboard. I’d keep checking back, because forecasts shift, but for now, leave the board at home.
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.
