The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Zaga (Koroni) stretch. I’ve got to be straight with you – this is going to be a tough one.
Right now, looking at the whole 16-day window, there’s a massive, barren gap at the start. From Sunday the 19th of July right through to the morning of Friday the 31st of July, we’re looking at a solid 12 days of absolutely nothing. The combined wave energy sits at zero (0) every single day. It’s flat, dead flat. The water is 81° and that’s a clear 4° warmer than usual for this time of year, which is notable, but it doesn’t do you any good without a wave.
The only glimmer of hope, and I mean the only one, arrives on the morning of Friday the 31st of July. We’ve got a tiny pulse of energy showing up – a 0.3ft swell from the SE with a period of 4 seconds. The combined energy is a paltry 1 (one). That’s not a surfable wave, not for a grown-up. It’s a ripple. Plus, Zaga is a sheltered spot that needs swell from the SSE to really work, and this tiny bump is from the SE, so it’s not even aiming properly. The wind that morning is light and cross-offshore, which is clean, but there’s nothing to ride.
After that little blip, it goes straight back to zero for the rest of the run into August. The consistency is rated as "rarely breaks," and this forecast is living up to that reputation. There’s no standout here, nothing to get excited about.
For a beach and point setup like this, with no swell and some decent wind, this is more of a kite-foiling or swimming kind of week than a paddle surfing one. Don’t hold your breath; we’ll have to wait for the next forecast change.
Rusty.
