The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for the Koroni area is a tough one to write up. The forecast is calling for a long stretch of nothing worthwhile, and I mean nothing.
The first real chance to even get your feet wet doesn't show up until Tuesday, August 11th, and even then it's a whisper. We're looking at a tiny 0.3ft swell from the SE with a super short period of 4 seconds. The combined energy is a measly (1) – basically a lake. The water is a touch warmer than normal for this time of year at 81°, but that's about the only positive.
The truth is, Zaga (Koroni) is a spot that rarely breaks, and this forecast confirms why. For the entire 16 days, the wave comment is always "poor surf conditions". We have a few mornings with light offshore winds from the NW, and even a glassy moment on Sunday afternoon, August 9th, and again on Sunday, August 16th, but with no swell to speak of, it's just a flat, clean ocean. It's not a bad place to be, but it's not a surf spot right now.
From the 11th, we get a few more days of that same tiny 0.3ft, 4-second ripple, but it's not enough to ride. The energy is just too weak. The rest of the window is a total blank. This is a blank run that's pretty normal for this area when it's this quiet. The forecasts can change, but right now, there isn't a single standout day or break. The only thing that could save this is if a new swell pops up, but as it stands, leave the board at home.
