The Lowdown
Alright mate, Rusty here. Let’s be straight with you: the 16-day window for Zaga (Koroni) is a flat spell with barely a ripple to get excited about. The first hint of any measurable energy isn’t until Tuesday the 8th of September morning, and even then it’s a tiny 0.3ft southeasterly bump with a short, weak 4-second period and combined energy of just (1). That’s barely a splash, not a wave. The water is sitting at a balmy 84°, which is much warmer than normal for this time of year by over three degrees, so it’s very unusual—you could swim in it, but you won’t be surfing it.
From that first morning, the outlook is a long, depressing gap. There’s no rideable surf at all for the rest of the day on the 8th, and the entire stretch from Wednesday the 9th right through to Monday the 21st of September shows nothing but zeros across the board. You get plenty of glassy mornings—like Wednesday the 9th, Thursday the 10th, and Friday the 11th all starting with light NNE winds and glassy conditions—but there’s simply no swell to push through. The afternoon windows are a mix of cross and light onshore winds, but again, without any wave height, it’s all just flat ocean.
The next tiny flicker doesn't show up until Tuesday the 22nd of September morning, with a 0.7ft southerly swell at 5 seconds and combined energy of (3), but it’s straight onshore from the SE at 9 mph, making it a total washout. Even then, the surf quality is rated poor. That afternoon sees a stronger 18 mph onshore blow with even smaller 0.3ft waves. Wednesday the 23rd offers a clean, glassy morning but once again, nothing in the water.
The bottom line: Zaga (Koroni) is a rarely breaks spot, and this forecast proves exactly why. There is no standout day, no single session worth paddling out for. If you’ve got a kite, those afternoon cross-off breezes in the second week might look more interesting than a surfboard, but for pure paddle surfing, this is a 16-day blank run. For this area, that’s not unusual given its sheltered exposure and inconsistent nature, so don’t write it off forever—forecasts can always change.
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. 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.
