The Lowdown
Alright, folks, Rusty here. Let’s have a look at the surf picture for Zaga (Koroni) over the next couple of weeks.
Plain and simple, it’s flat. There’s no other way to say it. The whole 16-day window is a bust for waves. We’ve got a big ol’ zero on the energy scale from now through the 29th of August. The swell charts are empty, and that means no rideable surf on offer at all. The only thing we’re seeing is that water temp is sitting at 83°, which is a good 4° warmer than what’s normal for this time of year. That’s a solid anomaly, so the water is going to feel like a warm bath even if we’re just floating around on a board with no waves to catch.
We’ve got a few glassy mornings, like on the 19th and 20th, but without any swell, it doesn’t matter how clean the surface is. The winds will be light or offshore for a lot of the time, which would be perfect if there was anything to ride, but there just isn’t. This spot is listed as sheltered and rarely breaks, so a blank run like this isn’t exactly a shock, but it’s still a bummer.
If you’re desperate to get wet, you’re better off finding a flat-water paddle or a swim. The only thing that might get interesting is if a strong wind kicks up some chop, but for the most part, it’s a no-go for surfing. All signs point to just keeping the board in the car and waiting for the next pulse of energy.
This is Rusty, signing off. We’ll get ‘em next time.

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.
