The Lowdown
Alright folks, Rusty here. Let’s get straight into it.
Well, I gotta be honest with you – this outlook is a tough one. We’re looking at a long stretch ahead with pretty much nothing to get excited about. For the entire 16-day window, Zaga (Koroni) is the only break on the cards, and it’s a real struggle.
The spot itself is a sheltered beach and point, which means it takes a very specific swell direction to get going. It’s a rare breaker, and that’s the story here. We’re coming off a blank start right through to the middle of September. For the first eight days, there’s just no surf to speak of. The water is sitting at a very warm 84°, which is a whopping 6° warmer than usual for this time of year – that’s a real anomaly, feels like a bath.
The first real glimpse of any swell shows up on the morning of Wednesday, 16 September with a tiny 3 ft swell from the southwest. The period is a short 5 seconds, so it’s a weak, local wind swell with very little energy (combined energy of just 51). The wind is light and cross-off, which is clean, but the swell is too small and weak to offer anything rideable. It’s still poor surf conditions.
Later that afternoon, the swell ticks up to 3 ft, but the period is still short at 6 seconds and the wind swings to a moderate cross-shore, ruining any chance of a clean wave. The energy is still weak (56). The rest of the window is a desert. There’s a tiny spike on the 22nd, but it’s 1 ft with a 4-second period – that’s not even a ripple.
The real kicker is that the optimum swell direction for this break is from the SSE, and the only swell we see is from the SW and SE. It’s just not lining up. For the rare days with a little bump, the wind is often clean or offshore, but there’s simply no power behind it. This setup is a classic case of a break that needs a specific storm to light it up, and that storm is not coming in this forecast.
Given the tiny surf and the lack of any real push, even with clean offshore winds, this is more of a swim or a paddleboard session than a surf. If you’re a beginner, these tiny conditions are safe, but there’s nothing to catch. For the rest of us, save the energy. The area is going through a real flat spell, and it’s not unusual for a sheltered spot like this to go quiet for a while.

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.
