The Lowdown
G’day, it’s Rusty. I’ve been over the charts for Zaga (Koroni) for the next couple of weeks, and I’ve got to be honest with you – it’s a dry spell. This break is known as a rarely breaks kind of place, and this forecast is proving that point. Right from the get-go, there’s a big gap with no real surf to speak of. From Tuesday the 28th of July through to Friday morning the 31st of July, the combined energy of all swells is sitting at 0 (zero) – just flat, glassy conditions or tiny wind bumps. On Friday morning the 31st, a tiny 0.3ft swell from the SE pops up with a 4-second period, but the combined energy is still only 1 (one) – barely enough to ruffle the surface. Then on Saturday the 1st of August, there’s a 1ft swell from the SSW, period of 2 seconds, again with combined energy of 1 (one). That’s the best it gets. The wind does offer some clean windows – we’ve got glassy conditions on Tuesday the 28th morning, and a few offshore breezes – but there’s no wave to clean up. The water temperature is about what you’d expect for this time of year. So, the reality is there are no standout sessions across this whole 16-day stretch. The surf just isn’t happening. For a spot that rarely breaks, this kind of quiet run is normal. Fingers crossed the forecasts shift, but for now, it’s a stay-home kind of outlook.
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.
