The Lowdown
Alright, let me level with you. It’s been a flat, frustrating stretch here. We’re looking at a run of days with nothing rideable, and that’s the honest truth. The first real pulse of energy doesn't even show up until later in the month, and even then, it’s not exactly setting the world on fire. But hold on, there’s a glimmer on the horizon.
Right now, through the middle of September, it’s just dead. We’re talking clear skies but zilch for surf. The water’s sitting about average for this time of year, so no surprises there. You’d be better off finding another hobby for the next week and a half. This spot, Zaga (Koroni), is a sheltered beach and point that rarely breaks, so it takes a decent push of swell to wake it up, and we just aren't getting it.
Finally, on the 23rd of September, things get interesting. A Wednesday morning shows a small pulse of 3ft swell from the southwest, with a period of 9 seconds. It’s not huge, but it’s something. The energy reading is weak at 95, but with light offshore northwest winds and clean conditions, it might be your only real window. It’s a beginner-friendly wave when it's small, and this is small. Just don't expect a classic. This is the standout, and honestly the only show in town.
The next couple of days, the 24th and 25th, stay clean but the swell just fades back out. The 25th has a tiny 0.7ft blip with a rain shower, but it’s more of a tease than anything. So, that’s it. One morning, the 23rd, looks like the single best bet in the whole 16-day window. Don’t hold your breath for anything else.

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.
