The Lowdown
Alright, grab a seat. Rusty here. Let’s get straight into it. We’ve got the Zaga (Koroni) stretch on the table – a *beach and point* setup that’s only rarely gonna fire for us. Looking at the full 16-day window, the honest truth is there isn’t a single moment where I’d tell you to wax up and paddle out. This is a real dry spell. There’s just no swell energy to speak of, and what little wobbles through is tiny and short period.
Right now, starting from Wednesday August 26th, it’s flat. Not even a ripple. That holds all through the rest of August and well into the first week of September. There are quite a few mornings with glassy, offshore, or light wind conditions, which is a total tease – the ocean’s flat as a pancake. The water temp is sitting pretty average for the time of year, so no wild anomalies there, but it doesn’t matter when there's no wave to ride.
We finally see a few pulses of life right at the very end. On Saturday September 5th morning, there’s a whisper of swell coming in at 0.4m (that’s about 1 ft for your deck log) from the SSW, with a period of 4 seconds. That’s straight-up windswell, barely enough to wet your wetsuit. The combined energy is just a meagre 7 – basically laughable. The wind is light from the NNW, so clean, but the swell is so weak it’s not even a surf for beginners; it’s a paddle.
Because Zaga is ‘rarely breaks’, this blank run isn’t a huge shock – it’s just how it goes here sometimes. Conditions are clean on multiple days, but with zero wave height, it’s not surfable. The whole setup is more suited to a snorkel than a surfboard right now. If you’re desperate for a splash, bring a bodyboard, but don’t hold your breath for surf.
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.
