The Lowdown
G’day, Rusty here. Gotta be straight with you—this 16-day window for Zaga (Koroni) is a tough one. We’re looking at a long, dry spell with barely a ripple on offer. The first real chance of anything rideable doesn’t show until Saturday the 15th of August, and even then, it’s just a tiny 0.3 ft swell from the SE with a short 4-second period and only 1 in combined energy. That’s barely enough for a float, let alone a wave. For a spot that rarely breaks anyway, this is a quiet period.
From now right through until Friday the 21st of August, it’s mostly flat with poor surf conditions day after day. You get some glassy mornings here and there—like Monday the 17th and Saturday the 22nd—but with zero swell, it’s just a flat ocean. The water temperature sits about 82°F with a positive anomaly of 3°F, meaning it’s a touch warmer than normal for this time of year, but that’s about the only highlight.
The best of the best in this outlook? Honestly, there’s no standout. The only tiny bit of action is Saturday the 15th morning, with that 0.3 ft SE swell and light N winds creating clean conditions on the cross-off. It’s still a beginner-friendly size, but it’s barely surfable. Given it’s a sheltered beach and point break, with the optimum swell coming from SSE, that SE direction is close but not perfect.
If you’re desperate for a paddle, Saturday the 15th morning is your only window. Otherwise, this is a blank run—pretty normal for the area when the swell’s this absent. Hang tight, forecasts can change.
