The Lowdown
Alright, Rusty here. Let's talk about what's going on for your local spot.
First off, the honest truth is we've got a flat spell stretching out for the full 16-day window. Over the next couple of weeks, starting from August 15th right through to August 30th, there is simply no swell at all to get excited about at Zaga (Koroni). The combined energy of all swells directed here is sitting at 0 for the entire forecast, so don't even bother waxing up the log.
Water temp is sitting at 83°F, which is about 4°F warmer than usual for this time of year – that's notably warm, like bathwater. You’d be swimming more than surfing. Wind conditions will vary from glassy mornings on the 19th, 20th, and 22nd of August, to some offshore breezes on the 26th and 27th of August. But without any wave height, clean conditions just mean a smooth lake surface.
Because Zaga rarely breaks and is sheltered from any real swell, this kind of blank run is pretty normal for the area. There are zero standout days here. If you absolutely need to get wet, it's a better setup for a kite or a SUP paddle than a surfboard, given the strong afternoon breezes. Keep an eye on the charts, but for now, the surf is off the cards.
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.
