The Lowdown
Alright, grab your board, but maybe leave it in the car for a while. It’s shaping up to be a proper flat spell for the foreseeable future. I’m looking at the next 16 days from the 10th through the 25th, and honestly, it’s a story of nothing but clean, glassy, and empty conditions – but no waves to speak of. We’re talking a total blank run for surf.
I’m parked at Zaga (Koroni) for this one, a sheltered beach and point setup. The water temp is sitting right about average for this time of year, which is a bit of a silver lining for a paddle, but that’s about all it’s good for.
The first few days, from the 10th through the 12th, are dead flat – no swell at all. The winds are light and mostly offshore or cross-offshore, so the ocean is as clean as a whistle, but there’s just nothing breaking. Then, on Wednesday the 12th morning, we see a whisper of a wave – a paltry 0.3ft of swell from the southeast with a 4-second period and weak energy (1). It’s basically a ripple, and not worth getting wet for.
We stay in this holding pattern through the 15th. Then, on Sunday the 16th, there’s a tiny uptick. The morning shows a tiny 0.7ft from the SSW with a 3-second period and still weak energy (1). The afternoon bumps up a touch to a knee-high 1ft from the same direction, with slightly more energy (4), but again, the period is a dismal 3 seconds. This is pure windslop, not surf. The wind shifts to a cross-shore moderate breeze, so the surface gets a little chopped up, but the size is still nothing.
From Monday the 17th all the way to the end of the window on Monday the 25th, it’s a total desert. The swell charts are blank. We get periods of glassy conditions, light offshore winds, and crystal-clear skies, but no groundswell, no swell, no nothing. Just a whole lot of flat, pretty ocean.
There are no standout days here. Not one. This is a classic blank run for this area, especially since the break itself is rare to break even when there is swell. It’s a sheltered spot, so it needs a very specific push from the SSE to get any size. Right now, it’s not happening.
We've got some nice, clean conditions with light winds, which if we had any swell would be amazing. But as it stands, you’re better off finding another hobby for a couple of weeks. Forecasts can always shift, but this one looks stubborn.

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.
