The Lowdown
Alright folks, Rusty here. Let’s have a look at the Zaga (Koroni) stretch over the next couple of weeks.
Right off the bat, I gotta be straight with you: this is a tough run. The forecast shows tiny, weak swell and a lot of flat spells. Zaga is a sheltered spot that rarely breaks, and this outlook backs that up. We’re looking at a long, dry gap with no real surf to speak of for the first 12 days. The water is running a touch warmer than normal for this time of year, sitting at 80°, which is nice for a swim, but not for the waves.
The entire first week and into the second is dominated by poor surf conditions. Saturday the 1st has a tiny 1ft from the SW with a super short period of just 2 seconds and combined energy of only 1 – that’s as weak as it gets. Winds are cross, messing up what little bump there is. Sunday the 2nd morning goes flat, and the pattern just repeats. We get a few glassy mornings on the 7th, 11th, and 12th, but with no swell showing up, it’s just a pretty lake out there.
It’s only on Thursday the 13th of August that we get a tiny pulse of life – a 1.0ft swell from the south with a 3-second period and combined energy of 2. Winds are cross-off, so it’ll be clean, but it’s not enough to get excited about. The morning of the 14th offers a tiny 0.3ft from the southeast with a 4-second period, and again, clean with offshore winds, but it’s barely a ripple.
Honestly, for this 16-day window, there are no good surf options. It’s a rare spot that rarely breaks, and this is one of those blank runs that’s pretty normal for the area. Keep an eye on the forecasts, though – things can change, and it tends not to stay this poor forever.
Rusty.
