The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. I’ve looked at the charts for the next couple of weeks, and it’s a tough one to call. Honestly, there’s not a single decent wave on the menu for this whole stretch. It’s a completely blank run.
We’re looking at a 16-day window where we just don’t see any real swell showing up. The energy readings are all at zero, which tells you everything you need to know. It’s flat. The only tiny blip we see is a little 0.3ft ripple on the 29th of August, but with a period of 4 seconds and a cross-onshore wind, it’s not going to be anything you’d want to paddle out for. That’s more of a lake ripple than a surfable wave.
Now, if you’re just starting out, the conditions aren't all bad. There are plenty of glassy mornings, especially around the start of September. The water is sitting at a very warm 84°, which is much warmer than normal for this time of year. That’s pretty unusual, so at least you won't need a thick wetsuit. But with no waves, it’s just a swim.
The winds will often be light or offshore, which would be perfect if there was anything to ride. But there isn't. This sort of blank spell can happen in this area, and with a spot like Zaga (Koroni) being a rare breaker anyway, it’s not a huge surprise. It’s a sheltered beginner spot that needs a very specific swell direction, and we’re just not getting it.
So, my call is to leave the boards in the car. Maybe go for a snorkel, but don’t get your hopes up for any surf. The forecast can always change, and with the conditions being as clean as they are, it wouldn't take much to get things going. But as it stands right now, it’s a no-go.
Keep it salty.

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.
