The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer for Zaga (Koroni).
Honestly, mate, it’s a pretty grim picture for the next couple of weeks. The whole 16-day stretch is a flat spell. There’s no proper surf to get excited about at all. The combined swell energy sits at a pitiful 0 or 1 (1) for the entire period, which is about as weak as it gets. You’re looking at a long, long gap of nothing but flat conditions and poor surf quality right through.
The water temperature is sitting at 83°F which is a whopping 5°F warmer than average for this time of year. That’s very unusual – the water is much warmer than normal, but it’s not doing a thing for the waves.
The first proper day we see any energy at all is on Saturday, 1st of August, when a tiny 1.0ft swell from the SW shows up in the afternoon. The period is a short 2 seconds, which is basically windslop, and combined energy is still just 1 (1). The wind swings cross-onshore from the SSW at 12 mph, making it choppy. It’s not surfable.
Sunday the 2nd of August offers a similar story: 1.0ft from the SSW with a 3-second period, and a cross-shore wind at 12 mph. The setup is more interesting for kite surfing than paddle surfing. It’s just not worth paddling out for.
For the rest of the forecast, from the 3rd of August right through to the 10th of August, there’s nothing. Zero swell. The wind is often light or offshore, but without any waves, it’s just a beautiful, flat lake. The break is sheltered and rarely breaks anyway, so this blank run is pretty normal for the area. Keep your board waxed and your eyes on the longer-range charts, but for now, there’s nothing to chase.
Rusty.
