The Lowdown
Right, cobber, Rusty here. Gotta be straight with you – the outlook for Zaga (Koroni) is a total flat spell for the next 16 days. We're looking at a solid two and a half weeks of nothing doing on the wave front.
The first real chance of even a ripple comes super late on Friday the 24th of July, with a tiny 1ft SSE swell, but it's got a period of just 2 seconds – that's zero energy, no push, and it's coming in on a cross-on breeze. It's a bit of a tease, but it won't surf. The combined energy is a measly 1, which is barely a whisper.
Before that, from the 15th right through to the 24th, it's a desert. Glassy mornings, calm afternoons, but with zero swell height across the board. The water's a touch warmer than normal at 80° – nice for a swim, but no use for a paddle.
Looking at the whole 16-day window, there's not a single standout. The spot is described as "rarely breaks," and this forecast proves it. For a sheltered setup like this, a blank run like this isn't all that unusual. The wind is often offshore or cross-off, and the conditions look clean, but without any swell, it's just a pretty, flat ocean. Forecasts can change, but right now, there's nothing to get excited about.
Keep the board in the bag, grab a coffee, and watch the horizon. This patch is a write-off.
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.
