The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one to write. We’re looking at a solid 16-day window for Zaga (Koroni), and the honest truth is, there’s nothing to get excited about. The whole forecast is a flat spell. There’s zero swell energy moving through here for the entire period. The combined energy of all swells directed here sits at a flat 0 for the vast majority of the days, and even when a tiny bump shows up, it’s only hitting 1. That’s barely a ripple.
Right out of the gate, from Thursday 3rd September, we’ve got clean, glassy mornings and some cross-off winds, but no swell to push. The water temperature is sitting at 84°F, which is a whopping 6°F warmer than normal for this time of year – that’s a very unusual anomaly, making it feel like bath water, but it’s flat as a pancake.
We’ve got a few days where a tiny 0.7ft to 1ft swell tries to show up, like on Tuesday 8th September with a 1ft SSW swell, but it’s got a short period of 2 seconds and a cross-shore wind. It’s barely surfable. Then again on Tuesday 15th September, there’s a 0.7ft SSE swell with a 4-second period, but it’s cross-onshore. For a spot that “rarely breaks,” this is par for the course. It’s a sheltered beginner setup, and the optimum swell direction is from the SSE, but the energy just isn’t there.
Honestly, if you’re looking for paddle surfing, you’re looking at a 16-day blank. There are no standouts, no best days. The offshore winds we see on Sunday 13th September morning (16 mph from the NNW) and Thursday 17th September afternoon (16 mph from the WSW) would keep the surface clean, but without any swell, it’s a waste. For a beach and point setup like this with such poor surf quality, it’s more interesting for a kite surfer than a paddle surfer during those breezy afternoons. Stay tuned, forecasts can change, but for now, it’s a flat spell.
Rusty.
