The Lowdown
Right then, let’s talk about this stretch. The honest truth is, we’re looking at a flat spell for the entire 16-day window here at Zaga (Koroni). There’s simply nothing doing in the way of surf.
From Tuesday the 25th of August right through to Tuesday the 9th of September, the wave energy reads a big fat zero (0). Just dead calm water, day after day. The water is sitting at 83°F, which is much warmer than normal for this time of year – feels like a bath. But that’s about the only notable thing going on.
You’ll get plenty of glassy mornings and some clean offshore and cross-off winds in there, which would be perfect if there were waves. But there aren’t. The only hint of something is on the afternoon of Wednesday the 9th of September, where a tiny 1 ft swell from the south-south-east shows up with a period of just 3 seconds. That’s not surf, mate, that’s just a ripple. Combined energy is a measly 1. And after that, it’s back to nothing.
Zaga is a sheltered spot known for being rare to break, so a blank run like this isn’t a huge surprise for the area. Unless you’re keen on a swim in warm water, there is zero reason to paddle out for the next two and a half weeks. Things change, but right now, it’s a total bust.
Keep your eye on the horizon, but it’ll be a while yet.

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.
