The Lowdown
Well, folks, it's Rusty here, and I've gotta be straight with you. We're looking at a 16-day window for Zaga, and honestly, it's a tough one. This spot, a sheltered beach and point break up in Koroni, is a real shy character – it says "rarely breaks" in the notes, and this forecast is proving that out.
The whole 16-day run is a long, flat stretch. We're talking about a solid gap of days with no surf worth paddling for. The first little flicker of energy doesn't show up until Wednesday morning, the 16th of September, and even that’s a whisper at best. From now until then, it’s a big zero.
That first hint on Wednesday morning, the 16th, is tiny. We're looking at a 0.7ft swell from the ESE, with a period of just 3 seconds. That's barely a ripple, and the energy is a pathetic 1. It's glassy, which is pretty, but there's nothing to ride.
We get a minor pulse on Thursday afternoon, the 17th, with the same direction but a slightly bigger 2ft swell. However, the period is still a short 4 seconds, and with onshore winds from the ESE at 9 mph, the conditions are poor. The wave energy is still very weak (18).
The best of a bad bunch, and this is being generous, comes on Friday afternoon, the 18th of September. The swell picks up to 3ft from the SE, with a period of 5 seconds, giving us a combined energy of 37 – still very low. The wind is light and variable, but it's onshore, so it's not ideal.
A couple of mornings have glassy conditions, like Saturday, the 19th, and again on Saturday, the 26th, but the swell is either tiny or non-existent. There's just no power behind it.
For the whole 16 days, the surf is consistently rated as "poor." There are no standouts, no hidden gems. This is a blank run, and for a spot that rarely breaks, it's a normal part of life here. Honestly, the setup looks more interesting for a paddle on a stand-up board than for a surfboard.
Keep your eyes on the charts, but for now, it's a waiting game.
Rusty.

Information about the Zaga (Koroni) Surf forecast
The above surf forecast table for Zaga (Koroni) provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
