The Lowdown
Alright, grab a seat. It’s Rusty here, and I’ve been staring at the charts for Zaga (Koroni) for the next couple of weeks, and I’ll be straight with you – it’s looking like a proper desert. There’s a whole lot of nothing on the horizon for a while.
To start, the water’s sitting at 84° and that’s a solid 6.8° warmer than what’s normal for this time of year. That’s not just a little warm, that’s a serious marine heatwave, so the water’s gonna feel like a bath.
We’ve got a big gap right at the start here. From Wednesday the 9th all the way through until early Tuesday the 15th, there’s just no swell at all. Zero. The ocean’s flat, and while the morning glass-offs and clean offshores are pretty to look at, there’s nothing to ride. The winds are mostly offshore in the mornings, which is a tease, but without any waves, it’s a no-go.
Then, on the morning of Tuesday the 15th, a tiny pulse of swell rolls in. We’re talking a weak 0.7ft from the SSE with a period of 2 seconds. Trust me, that’s not surf, that’s just a ripple. The wave energy is basically nothing (1). It’ll be cross-shore and chopped up anyway.
Things get a little more interesting starting Wednesday the 16th. We see a *slightly* better pulse, with a few small waves building. On the morning of the 16th, we get a 1.6ft, 4-second wave from the SE. The combined energy is weak at (9), but at least it’s something. The wind is light and cross-offshore, which should keep it clean. This picks up a touch on the morning of Thursday the 17th with a 1ft, 6-second swell and glassy conditions. Honestly, these are the best of a pretty bad bunch, but we’re still talking about knee-high mush at best. This little bump fades out by Friday, and then it’s flat again.
From Saturday the 19th, we go completely flat again, and that’s it. The forecast just runs out of ideas. The entire rest of the period up to the 24th is a big fat zero on the swell front. Nothing. Nada.
So, here’s the bottom line: Zaga (Koroni) is a sheltered spot, and it’s just not showing any love in this 16-day window. The one or two tiny days around the 16th and 17th are not really worth paddling out for unless you have a longboard and a whole lot of patience. The spot itself is inconsistent and rarely breaks, so this blank run isn’t a total shock. But for anyone hoping for a wave, I’d say keep your board in the car, the forecasts can change, but right now it looks like a write-off. The best we can hope for is a bit of a warm water splash. Signing off.

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. 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. If you surf the same spot (Zaga (Koroni)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
