The Lowdown
G'day, Rusty here. Look, I've gotta be straight with you – the outlook for the next couple of weeks is a tough one. We've got a big, flat stretch ahead, so don't get your hopes up for any serious paddle sessions. The water is sitting at a very warm 83°, which is much warmer than usual for this time of year, so at least a dip will be nice.
Right now and for the vast majority of the forecast, there is simply no swell at all. From Sunday the 23rd of August all the way through to Monday the 31st of August, it's a total blank. Zero energy, zero waves. It's a real bummer. The wind is often offshore and clean, or even glassy at times, which would be perfect if there was any swell, but there isn't. The one small blip comes on the afternoon of Monday the 31st of August, where we see a tiny 0.3m (1 ft) swell from the SSE with a weak period of just 2 seconds and minimal energy (1). It's barely a ripple and with a cross-offshore breeze, it's not worth getting excited about.
After that, we go flat again. The entire first week of September looks just as grim. From the 1st through to the 7th of September, it's all zeros. The wind stays mostly clean and offshore, but the ocean is dead flat. It's a long, frustrating run of nothing.
Honestly, Zaga (Koroni) is a sheltered beach and point that rarely breaks, and this forecast confirms why. It's just not the spot for consistent surf. If you're desperate, the setup and the strong, clean winds might be more interesting for kite surfing than paddle surfing. But for us wave hunters, it's a waiting game. The forecasts can change, and this dry spell won't last forever. Hang in there.
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.
