The Lowdown
Well, let’s be honest with you right off the bat. The next couple of weeks are looking pretty bleak for waves here at Zaga (Koroni). I’ve scanned the forecast, and the surf is just not showing up. We’re looking at a long stretch of flat, small, or totally non-existent conditions.
The only real blips of any swell energy are tiny. We’re talking about a negligible 2ft on Saturday the 29th, but that’s with a short period and weak energy (10). Then again on Friday the 4th of September, we might see a faint pulse of 1ft, but again, the energy is almost nothing (2). These are not waves you’d paddle out for; they’re barely ripples. The entire 16-day window has no proper swell, with the combined energy sitting at zero or single digits for most of it. It’s a flat spell, plain and simple.
Before that, the water is a notable 83°F, which is much warmer than usual for this time of year—that’s a real standout, but it won’t help you get a wave.
The winds are mostly light and variable, with some glassy mornings, especially on the 27th, 28th, and the 31st. But with no swell, glassy conditions are just a pretty, flat ocean. The spot is sheltered, and it’s a beach and point setup, but even so, there’s just nothing coming in. This break rarely breaks, and this forecast is a perfect example of why.
We’ve got a few afternoons with cross-shore winds kicking up a bit of chop, but honestly, with no waves, it’s a non-issue. The outlook is poor. There are no good surf options in this 16-day window. Keep your board in the car, maybe go for a paddle if you’re desperate, but don’t expect a single decent wave. Forecasts can change, but right now, it’s looking like a total write-off.
