The Lowdown
Hey crew, Rusty here, checking in on the Zaga (Koroni) region.
I’m not going to sugarcoat it – this 16-day stretch is a total flat spell. There are no real waves to chase. The charts show a long, boring run of nothing, with just a few tiny, useless bumps that aren't worth paddling out for.
It starts on Friday, July 24th. The morning is clean but flat. In the afternoon, we see a tiny 0.3m swell from the south with a period of 2 seconds – that’s not a wave, that’s wind chop. The combined energy is a pathetic 1 (1). A gusty SW wind at 20 km/h doesn’t help.
Saturday the 25th is even worse. A 0.3m ESE swell with a 3-second period (1) is crossed up by an onshore breeze. Total waste of time.
From Sunday the 26th right through the end of July, there’s zero swell. We get some gorgeous glassy mornings, like Tuesday the 28th, but there’s not a ripple to ride. The same story continues into early August. On the 31st of July, the afternoon goes glassy again with a 0.3m SW swell, but it’s only 2 seconds – that’s a lake ripple.
The first week of August is the same. Clean offshore winds, flat surf. The last few days of the forecast, like Friday the 7th and Saturday the 8th, are glassy and completely flat.
Zaga (Koroni) is a sheltered, rarely-breaking spot, and this forecast proves it. A long, blank run like this is normal for the area in summer. The water temperature is about average for the time of year.
There’s no surf to be had. It’s a swimming pool out there.
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.
