The Lowdown
Alright folks, Rusty here. Let's be straight with you about the local stretch we're looking at.
Well, I gotta be honest with you, this is a tough one to write. We're looking at a 16-day window that starts with pretty much nothing going on. The first proper surf worth mentioning doesn't show up until the very end of the run. The water temp is sitting at a warm 81°, which is a good couple of degrees above normal for this time of year, so it's noticeably warmer than usual. That's about the only thing working in our favour for a while.
From Friday 17 July all the way through to Saturday 26 July, it's a flat spell. No swell to speak of. The wind is often clean or glassy, and the skies are clear, but mate, there's just no waves. It's a total blank run. That's a solid nine days of nothing.
Then, finally, on the afternoon of Sunday 26 July, we get a whisper of life. The swell at Zaga (Koroni) shows up – a tiny 1 ft swell from the southwest, with a period of just 2 seconds. That's barely a ripple. The combined wave energy is a measly 1, so it's about as weak as it gets. The wind is a cross-offshore breeze, which would keep the surface clean, but there's just no power in the water. This is a beach and point break that rarely breaks anyway, so you’d be lucky to find a rideable bump.
The outlook doesn't improve much. We see another tiny 1 ft, 2-second pulse from the southwest on the afternoon of Saturday 1 August, with the same low energy. The wind is a light cross-shore, so the surface would be a bit bumpy.
So, the honest truth is there's no standout session here. There's no wave to get excited about. The whole 16-day forecast is a bust for surf. With a spot that rarely breaks, this kind of run is pretty normal for the area. It's not going to stay poor forever, but for now, the only thing to do is wait for the forecasts to change.
Rusty.
