The Lowdown
G’day, Rusty here. I’ll level with you, it’s a rough stretch of calendar to be a surfer. We’re looking at a long, flat patch for the better part of a fortnight. Nothing to do but shake your head and check the horizon.
The first week and a half is a total write-off. We’re talking no swell, and what little kicks up is messy, short-period churn from the east. You’d be fighting the chop more than riding a wave, and honestly, it’s not worth the paddle. The only thing that breaks the monotony is a tiny pulse on the morning of the 27th. It’s a small window, but it’s a window.
Sunday the 27th is it. Zaga (Koroni) is the spot. It’s a beach and point break, and it’s one of those rare ones that only breaks sometimes. The swell direction is from the SE, and despite the size being nothing to write home about, the glassy morning conditions will make it look better than it is. The combined energy is only 33, so it’s pretty weak. It’s an easy, small wave for the beginners to have a paddle on, but it’s not going to show you the light. The water is 28°, which is a massive 4° above average for the season—a real bathtub moment, but doesn’t change the fact there’s no push.
After that, it’s back to nothing. The swell is gone by lunch, and the rest of the run is small, weak, and choppy. By the 30th and 1st we’re looking at strong onshores hitting 25 km/h and some rain, so you can take the board off the roof and leave it there. If you see anyone on a kiteboard, that might be more interesting than a surfboard.
Overall, this is a lean run. The one tiny window is on the 27th, and it’s for beginners who just want to get wet. For anyone else, it’s not worth it. But hey, this area doesn’t stay this flat for long, so I’m holding out hope for a change in the pattern. Until then, you’re on land.
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.
