The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
Honestly, mate, it’s a pretty bleak run. We’re looking at a long stretch of basically nothing on offer for Zaga (Koroni). The first hint of something surfable doesn’t show up until Tuesday the 15th of September, and even then, it’s not worth getting wet for. We’ve got a tiny 2.6ft swell from the southeast, but it’s short-period slop at 5 seconds and the wind is a cross-on from the east at 6 mph. The water is sitting at a very unusual 84°, which is a massive 7° warmer than normal for this time of year – that’s a real standout, but it doesn’t help the waves. The combined swell energy is weak as dishwater at (34). It’s a beginner-friendly beach and point set-up, but the quality is poor.
From Wednesday the 16th right through to Tuesday the 29th of September, we are looking at a massive gap – over a week and a half – with barely a ripple. You’ll see some glassy mornings and clean, offshore breezes, but the swell registers are flat-lining at zero or next to nothing. A tiny 1.3ft to 2ft pulse shows up on Wednesday the 23rd and Thursday the 24th, but the wind is onshore or cross-onshore, and the period is a weak 4 seconds. The combined energy never gets above (12). It’s honestly more interesting for a kite surfer than a paddle surfer on those days.
There’s no standout session in this window. The only thing close to a wave comes right at the end, on Monday the 28th of September afternoon, with a 1ft, 2-second windswell from the southwest – but that’s barely a ripple. This area is going through a proper flat spell. For a spot that rarely breaks anyway, this is a pretty normal blank run for the region. Forecasts can change, but right now you’re better off doing something else.

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.
