The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got Zaga (Koroni) on the radar, and honestly, it’s a tough one. This is a sheltered beginner-friendly spot that rarely breaks, and looking at the whole 16-day window, there’s just nothing happening. The forecast shows zero wave energy for the vast majority of the period, with only a few tiny, weak pulses that barely register. You’re looking at a long, dry gap from the start right through to the end of the first week.
The only flickers of life come on the 31st of July with a tiny 0.3ft SE swell, period 4 seconds, and combined energy of just 1 – that’s weak. A similar little bump shows up on the 9th of August, again 0.3ft from the SE at 4 seconds, and another on the 10th of August. The water temp is sitting at 79°, which is about normal for the time of year. Wind conditions are mostly light and variable, with some glassy mornings on the 3rd of August and the 13th of August, but with no swell to work with, it’s all just flat and clean.
By the second week, the pattern doesn’t change. A few more of those tiny, short-period pulses appear on the 11th of August, but they’re not enough to get excited about. For a spot that already rarely breaks, this is a blank run. The setup here is more interesting for a paddleboard or a longboard in a bathtub than a surfboard. If you’re desperate for a splash, the morning of the 9th of August has a clean 0.3ft with offshore winds, but that’s about it. Keep an eye on the longer range, but don’t hold your breath.
Rusty.

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.
