The Lowdown
Alright, Rusty here. Let's talk about what's happening with your local surf.
First up, folks, it’s a quiet picture. The water temperature is sitting around 84°F with an anomaly of 6°F warmer than normal – that’s pretty unusual, it feels more like a bath than the sea for this time of year. But looking at the waves, we’ve got a flat spell that lasts for the first several days. From the 4th of September right through to the morning of the 8th, there’s simply no swell registering at all. Not a ripple. You get some great offshore and glassy conditions in that time – north winds early on, a little glass-off here and there – but nothing to ride.
Then on Tuesday the 8th of September, we finally get a blip. The morning shows a tiny 0.3ft wave from the southeast, with a period of 4 seconds. That’s a weak, short-period little bump, not enough for a proper surf. The combined energy is only a 1, and honestly that’s barely a dimple on the water. The wind is glassy, which is pretty, but there’s nothing to push you along.
The rest of the period follows the same pattern. Every morning from the 9th to the 19th of September and most afternoons, it’s the same story: no meaningful swell. A lot of clean conditions with offshore or cross-offshore breezes from the north-northwest and northwest, especially mornings. The afternoons get a bit more wind from the southwest or west, sometimes gusty. But with zero to 0.7ft swell and periods that never get above 4 seconds, it's straight-up flat.
Zaga (Koroni) is a beach and point break that *rarely breaks* anyway, and unfortunately this forecast window is a long, blank run of poor surf conditions. There just is no surf on offer. The setup is sheltered, and we’d need a decent south-southeast groundswell to get it working, but nothing like that shows up in the next couple of weeks.
If you’re desperate for a paddle, maybe a longboard on the morning glass-offs, but realistically, for proper waves, this is a write-off. The blank run is pretty normal for this spot when the swell doesn’t line up.
Stay patient. Rusty.
