The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the surf outlook for Zaga (Koroni) over this 16-day stretch is a tough one to write. I’m looking at a whole lot of flat, clean ocean, and not a single wave worth paddling for. The swell energy is sitting at zero (0) for the entire period. That’s about as empty as it gets.
The water is running warm at 83°F, which is a solid 4°F warmer than the norm for this time of year. For the first spot I’m checking out, that’s a notable bump – the ocean’s feeling more like a bath than the usual late-summer mix. It’s a nice thought, but it doesn’t help us find a wave.
We’ve got a clear run of weather, mostly light offshore and glassy conditions through the mornings for the first week, especially around the 19th and 20th of August with that total calm. If there were waves, it would be perfect. But there aren’t. We’re looking at a solid stretch of nothing for the first week, all the way through to the end of August. The winds stay mostly offshore or clean, but with no swell, it’s just a pretty, flat ocean.
Moving into the final days of the month and the start of September, the story doesn’t change. The mornings stay clean, a few afternoons get a bit of cross-shore chop, but the core problem remains: there is zero swell on the cards. We’re talking a full 16 days with no recommendations. This is one of those blank runs that just happens in this area. When a spot like Zaga – which already only rarely breaks – goes quiet, it can stay quiet for a while.
So, where does that leave us? It leaves us with a flat spell that’s going to test the patience of even the most dedicated soul. There’s nothing for the beginners, nothing for the experts. The only thing that looks like it has any energy in that entire window is the breeze on the 28th, blowing a fresh 22 mph offshore. But with no swell to push against, that’s not going to do anything for a surfboard. That setup looks far more interesting if you’ve got a kite.
Keep the boards waxed and the quiver ready. This kind of dead spell doesn’t last forever, and the forecasts can change on a dime. When the swell does decide to show, the conditions will be pristine. But for now, we wait.
