The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a good, long look at the forecast, and I’ll be honest with you—this is a tough one.
Right off the bat, the outlook for Zaga (Koroni) is a blank. There’s simply no surf on offer across this entire 16-day window. The combined wave energy is zero (0) every single day, meaning there’s no swell to speak of. From Saturday the 18th of July right through to Sunday the 2nd of August, it’s flat. That’s a solid 16-day gap with nothing to ride.
The water temperature is sitting at 81°, which is a full 4° warmer than usual for this time of year. It’s noticeably warm, but without any waves, it’s just a bath.
The wind does look clean at times, especially those mornings with glassy or light offshore conditions from the NW, but it doesn’t matter when there’s zero swell. On a few afternoons, the wind picks up from the SW or W, creating some cross-chop, but again, nothing to surf.
Here’s the thing: Zaga is described as a beach and point break that rarely breaks. It’s sheltered, so it needs a very specific swell direction (SSE) to light up, and that’s just not happening in this forecast period. The setup is so poor that if you’re looking for any kind of wave riding, this would be more interesting for a kite surfer on a windy afternoon than a paddle surfer.
This kind of blank run is more normal for the area when the swell direction is off. It tends not to stay poor for long, but for now, the forecast is what it is.
Rusty, signing off.
