The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you—this next 16 days is a total write-off for surf. There’s nothing on offer that’s worth paddling out for. The whole stretch from Tuesday, 21 July, right through to Wednesday, 5 August, is a flat spell with no real swell. You’ll see a few tiny bumps—like 1 ft on the afternoon of Thursday, 23 July, and a 1.0 ft on Monday, 3 August—but the combined energy is practically zero (values like 2 and 1), so it’s not even close to rideable. The water’s sitting at 82°F on the 21st, which is much warmer than usual for this time of year, over 5°F above average, so that’s a weird one for Zaga (Koroni). But with no waves, it doesn’t matter.
The break itself is a sheltered beach and point setup, rarely breaks, and the optimum swell direction is SSE, but we’re not seeing anything meaningful from that quarter. Winds are often offshore or glassy through the mornings, which would be mint if there was any swell, but there isn’t. It’s a beginner-level spot, but even beginners need a ripple. Honestly, this is one of those blank runs that’s more normal for a sheltered spot like this—it tends to go quiet for long stretches. Don’t hold your breath; forecasts can change, but right now, there’s not a single day to mark on the calendar. 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.
