The Lowdown
Alright folks, Rusty here. Let’s be straight with you – if you’re looking for waves around these parts over the next couple of weeks, you’re gonna be staring at a whole lot of flat water. This stretch here is a real quiet one.
For Zaga (Koroni), the outlook is a complete bust. There is simply no surf to speak of for the entire 16-day window. From the 30th of August all the way through to the 14th of September, we’ve got a string of zeros for swell energy (0). That means nothing, zilch, nada. The water temp is sitting at 83°F, which is a hefty 5°F warmer than usual for this time of year – that’s seriously warm, almost weird for the season.
The only tiny flicker of life comes on the morning of Tuesday the 8th of September, when a tiny 0.3ft swell from the SE shows up with a period of just 4 seconds and a combined energy of only 1. That’s a barely-there windswell, not worth paddling out for at all. Before and after that, it’s all dashes for wave height and energy.
On the bright side, the winds are often light and clean, with plenty of glassy or offshore conditions forecast. But with no swell to work with, those perfect winds are wasted. For a break that’s already a rare breaker and inconsistent, this kind of blank run is more typical for the area – it just goes to show, this isn’t a place you can count on for a quick fix. Unless you're keen on a flat-water paddle or just a swim in that warm water, there’s nothing doing here for surfers.
Rusty.

A general guide to surfing at Zaga (Koroni) can be found by selecting the local surf guide option on the grey menu. Our Zaga (Koroni) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
