The Lowdown
Alright, Rusty here. Gotta be straight with you – this next 16 days is a tough one to call.
Right from the start on Friday, August 14th, we’ve got zero energy. The ocean’s flat out flat here at Zaga (Koroni). The combined wave energy is a measly 0, so there’s nothing to ride. This dead spell stretches right through the whole forecast period. We’re looking at an empty run until the very end of August. There’s simply no surf on offer.
The water’s sitting at about 83°F, which is a touch warmer than normal for this time of year, but that’s hardly going to help if there are no waves.
To make matters worse, Zaga is a sheltered spot that rarely breaks anyway, and the guidance confirms it’s for beginners. With no swell on the horizon and those clean offshore winds just blowing over a flat ocean, it’s a kite-surfing scene more than anything if you’re desperate to catch something. For a paddle surfer, this is a write-off. I’d say this blank run is pretty normal for the area with this setup, but stick with it – forecasts can change.
Stay patient.
Rusty.

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.

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.
