The Lowdown
Alright, mates, let’s talk about Zaga (Koroni). I’ve looked at the charts for the next 16 days, and honestly, it’s a flat spell. This break is a sheltered beach and point setup, and it rarely breaks anyway—so this kind of blank run is pretty normal for the area. There’s simply no swell to speak of from July 19 all the way through to August 3. The water temperature on July 19 morning was 82°F, and that’s nearly 5°F warmer than usual for this time of year—the warmest I’ve seen in a while. But without any waves, that warmth doesn’t help for surfing.
The wind sticks around in the glassy to offshore range most mornings, so if there were any swell, conditions would be clean. But the combined energy of all swells is zero for the entire period—just a couple of tiny readings on late July afternoons, with a tiny 1ft SSE swell on July 24 afternoon, but that’s a 3-second period, basically wind chop, and the wind was cross-onshore. Not worth paddling out for. So there’s nothing to recommend. If you’re desperate for a paddle, you’d be better off with a longboard on a flat day, but I’d say don’t hold your breath. Forecasts can change, but for this spot, it’s rare to see anything good in a 16-day window, and this run is no exception.

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.
