The Lowdown
Alright folks, Rusty here. Let’s get straight into it. I’ve had a good look at the charts for the next 16 days and, well, I’ll be honest with you – it’s a tough one. The only spot on the radar is Zaga (Koroni), and the outlook is a proper flat spell.
Right from the start, Tuesday the 4th of August through to the end of the 16-day window, there’s simply no swell to speak of. The combined energy of all swells directed here is a big fat zero (0) for every single session. That’s not a typo. We’re talking about a full 16-day stretch with zero wave energy. The water temp is about average for this time of year, so at least you won’t be cold while you’re staring at a flat ocean.
Zaga is a rarely-breaking, sheltered spot that needs a very specific SSE swell direction to wake up, and that just isn’t happening. The wind will be clean and light on many mornings, with a few glassy moments on Friday the 7th and Saturday the 15th of August, but without any swell, that’s just a mirror. For a break that’s already inconsistent, a blank run like this is more normal than unusual for the area.
I hate to say it, but there’s nothing to chase here. No standouts, no sneaky waves, just a long wait. We’ll have to hope the forecasts change for the better. Keep the boards waxed anyway.
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.
