The Lowdown
Alright, Rusty here again, but in feet and Fahrenheit for you. Let’s be straight. Lookin’ at the next 16 days for Zaga (Koroni)… It's gonna be a tough stretch. Honestly, there’s not a single day in this whole window that’s worth paddling out for. The forecast is a flat spell, plain and simple.
We start off from Saturday the 12th through to Monday the 14th with zero swell showing – just clean conditions and not a wave to surf. By Tuesday the 15th, a tiny bit of energy creeps in, but we’re talking ankle-snappers at 0.7ft to 1ft from the east and southeast, with periods barely reaching 4 seconds. The combined swell energy is basically nothing (1 to 4). It’s not surfable.
Wednesday the 16th and Thursday the 17th see a slight bump, with 2ft to 3ft swell from the southeast, period around 5-6 seconds. Combined energy gets up to 64 – still weak, weak, weak. Winds are mostly cross-onshore or onshore, so it’s choppy and messy. Poor surf conditions is right.
Then on Friday the 18th, we get the biggest pulse of the whole forecast: 5ft swell from the southwest with a 9-second period. That’s a moderate energy reading (373). But here’s the bummer – the winds are cross-shore, light, but the spot stays sheltered from that direction, and the overall quality is still flagged as poor. It’s a tease more than anything.
After that, it’s back to flat or near-flat from Saturday the 19th all the way through to the end on Sunday the 27th. A couple of mornings might look glassy, but there’s just nothing underneath you. No swell, no hope.
Water temp on the first Saturday is sitting at 83°F, which is over 7°F warmer than usual for this time of year. That’s very unusual – the Med is cooking. But warm water doesn’t make waves.
Forget about beginner, expert, or crowd talk. There's nothing to ride. Even the kites would struggle most days. This break rarely breaks anyway, and this 16-day block proves it. Forecasts can change, but there’s nothing on the table right now.
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.
