The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for our little slice of coast. I gotta be straight with you – we’re looking at a long, quiet stretch ahead. There’s no surf to speak of for the entire 16-day window. It’s a blank run, and for a spot like Zaga (Koroni) that rarely breaks anyway, this kind of dead spell isn’t a shock. The sea is just flat, plain and simple.
For Saturday the 29th of August, we get a tiny pulse of 1ft from the SE with a period of just 4 seconds – that’s pure wind chop, not a wave you want to paddle for. The combined energy is weak (2). The wind goes from a light breeze on the morning to a stiff cross-onshore in the afternoon, so it’s messy on top of being tiny. Water temp is a balmy 84° though – that’s 5.4° warmer than average for this time of year, so the ocean feels like a bath.
Then from Sunday the 30th of August right through to Sunday the 13th of September, every single entry shows nothing. Zero swell. The wind often goes glassy in the mornings and clean offshores in the afternoons – perfect conditions if there were any waves. There are moments of light offshores and glassy mornings that would have been epic, but without any swell pushing in, it’s just a flat, pretty sea.
So, the honest truth: there are no good surf options in this 16-day window. Not one standout, not one session worth jumping in for. If you’re desperate for a paddle, you’re paddling on a lake. But the forecasts can change – it tends not to stay this flat forever. Keep an eye on the horizon.

A general guide to surfing at Zaga (Koroni) can be found by selecting the local surf guide option on the grey menu.

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.
