The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the cards.
Honestly, it’s a pretty bleak picture overall for Zaga (Koroni). We’ve got a 16-day window staring at us, and the first sniff of anything rideable doesn't even show up until late in the run. For the bulk of the next two weeks, you’re looking at a total flat spell. From now through to around the 24th of August, the energy levels are sitting at zero. Dead flat. Glassy mornings and clean afternoons are nice for a swim, but there’s nothing to paddle into. It’s a tough stretch.
The only faint glimmer of a possibility pops up on Monday the 24th of August in the afternoon. The swell shows a tiny pulse from the SSW with a height of only 0.7 ft and a period of just 2 seconds. The combined energy is a measly 1 – that’s barely a ripple. Offshore wind from the WSW will keep it clean, but with that size and period, we're talking about little more than a knee-high bump that's barely breaking. It’s not really surfable for anyone.
For the rest of the forecast, it’s the same story: plenty of offshore and glassy conditions, especially mornings, but no swell to go with them. The wind turns strong offshore towards the end of August – the 27th and 28th – with gusts up to 25 mph, but again, on a completely flat ocean, that’s just a stiff breeze and nothing more.
So here’s the deal: if you’re desperate, maybe bring a longboard for that tiny bump on the 24th, and just enjoy the clean conditions. There are no standout sessions. None. The water temp is sitting at a very warm 83°, which is much warmer than you'd expect for this time of year, so at least a dip in the sea will be pleasant if the surf isn’t.
Keep an eye on it, though. Forecasts change.
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.
