The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you: this is a tough one. Zaga (Koroni) is a sheltered, rarely-breaking setup, and for the entire 16-day run, there’s basically nothing on the cards. The first few days are a total write-off. From Sunday the 19th of July right through to the end of the month, the wave energy is flat – zero on the combined energy scale. We’re talking a blank run of about two weeks without a single worthwhile wave.
There’s a tiny blip on Saturday the 25th of July afternoon, with a tiny 1ft swell from the SSE and a period of only 2 seconds, carrying a combined energy of just 1. That’s not surf, that’s a ripple. It’s a beach and point setup, but with that little energy and a cross-shore wind, it’s not even worth paddling out for. The water temp is sitting at 82°, which is much warmer than normal for this time of year – over 5° above average, so you’ll be swimming in bathwater if you do go in.
The only real bright spot on the wind front is the occasional glassy or clean offshore morning, like Tuesday the 21st of July morning with glassy conditions and no wind, or Wednesday the 22nd of July morning with a light offshore. But with no swell to work with, it’s just a tease.
For the second week, it’s more of the same – tiny swells, mostly clean winds but no wave energy to speak of. The setup here is more interesting for kite surfing than paddle surfing when there’s any breeze, because the swell just isn’t there for us.
Honestly, for a spot that rarely breaks, this kind of blank run is more normal for the area. The forecasts can always change, but right now, there’s nothing to get excited about.
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.
