The Lowdown
Alright crew, Rusty again, this time in feet and miles per hour. Let’s break down Zaga (Koroni) for the next 16 days. I’ve got to be straight with you – this is about as quiet as it gets. The entire outlook is a flat spell, with almost nothing to even call a wave.
Kicking off on the 10th of September, it’s completely flat. The water is 84°F, which is a whopping 7°F warmer than normal – that’s really unusual, feels like a hot tub. Winds are light and glassy, but there’s zero swell. That theme carries through the 11th, 12th, 13th, and 14th – perfect offshore winds at times, but a big fat zero for wave height.
Then on the 15th of September, Tuesday afternoon, we see a little pulse: 1ft from the SE with a period of just 2 seconds and a combined energy reading of 1 – that’s as weak as it gets. It’s cross-onshore and choppy, not worth wetting your wetsuit. The rest of the first week is more of the same: tiny 0.3ft bumps on the 18th, 19th, and 20th from the SE or S, with periods of 4 to 6 seconds, and energy still stuck at 1. All of it is poor.
From the 21st through the 23rd of September, it’s flat again until we see another 0.3ft pulse from the SE on the morning of the 23rd, energy at 2. The 24th is similar, and then it’s back to nothing for the final day on the 25th.
For Zaga, a sheltered break that rarely breaks, this kind of extended flat run is pretty typical. It’s a beginner-friendly spot, but there’s just no swell energy. Combined energy readings stayed below 100 (maxing out at 2) the whole time, which tells you the ocean is asleep. On the few days with a tiny bump, the wind was messy or onshore.
Honestly, this setup looks more interesting for kite surfing than paddle surfing on those rare windy afternoons. For now, don’t expect any waves. It can change, but this is a long stretch of nothing.
Rusty.

A general guide to surfing at Zaga (Koroni) can be found by selecting the local surf guide option on the grey menu.

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.
