Table - best surf conditions forecast for Zaga (Koroni) over the next 16 days.
Alright folks, Rusty here. Gotta be straight with you – this outlook is a tough one. We're looking at a full 16-day window, but honestly, there's nothing worth paddling out for at Zaga (Koroni). The whole period is a flat spell.
The first sign of any energy doesn't show up until the afternoon of the 23rd of July, and even then it's just a tiny 1ft SE windswell with a weak 3-second period. The combined energy is a measly 1 (weak energy), so it's barely a ripple. The morning of the 24th of July is the same story with less than 0.5ft. Beyond that, it's a total blank. The water temp is a notable 80°F with a massive anomaly of 4°F, making it much warmer than usual for this time of year, but that doesn't help us get a wave.
We're talking about a break that rarely breaks, and this forecast confirms it. There's a long stretch of absolutely nothing. The wind is often offshore or glassy, especially on the mornings, but with no swell to work with, it's just a pretty lake. For a sheltered spot like this, a total flat spell is more normal than a surprise.
If you're desperate for a paddle, you might get a knee-high bump on that 23rd afternoon, but it's not surf. This setup is more interesting for a kite than a surfboard. I'll be watching the charts, but it's a no-go for now.
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.
