The Lowdown
Alright, Rusty here. Let's have a look at the charts for the next couple of weeks.
Honestly, mate, it's a bit of a tough one to call. The outlook for the next sixteen days is pretty much a flat, empty ocean. There's not a single wave on the cards for the whole stretch. The first real chance of anything, and I mean *anything*, comes up on Sunday, the 30th of August, and it's a complete dud – zero energy, no swell to speak of. The situation doesn't improve at all from there.
We're looking at a solid two-week gap with no surf whatsoever. You'll see some nice, clean mornings with light offshore breezes, especially around the 3rd and 7th of September, but there's just no swell to push through. The wind will be good for a surf, but the ocean is giving us nothing. It's a real bummer.
The only spot in the frame is Zaga (Koroni), a beach and point setup that's sheltered and rarely breaks anyway. It's a beginner-friendly spot, but with the swell energy sitting at a flat zero, there's absolutely nothing to ride. The water is warm, sitting at 83°F, which is much warmer than usual for this time of year, but that's a small consolation when you're staring at a glassy lake.
For a few days in the second week, like the 7th and 9th of September, the offshore winds are perfect, but it's all for nothing with no waves. If you're desperate for time on the water, this setup is more interesting for a kite. For paddle surfing, it's a complete write-off. Don't hold your breath; forecasts can change, but this one's looking pretty set in stone.
Rusty.
