The Lowdown
Alright, Rusty here. I've been staring at the charts for Zaga and, well, I'm gonna be straight with you – it's a long, quiet stretch ahead. The whole 16-day window from now through to the 4th of September shows nothing but a flat ocean. The combined energy of all swells directed here is sitting at zero for the entire period. That's not a typo. There's no swell, no waves, no surf to speak of.
So, what's the story? Zaga (Koroni) is a beach and point break that's rated as a beginner spot, but it rarely breaks and it's sheltered from most swells. Looking at the guidance, it needs a swell from the SSE to get going, and we just don't have one. The water temperature is a warm 83°F, which is a whopping 4°F warmer than usual for this time of year – much warmer than normal – but you won't be needing a wetsuit because you won't be surfing.
The winds are often light or offshore, and there are plenty of glassy mornings, like on Thursday the 20th, Sunday the 23rd, and Sunday the 30th of August. But with no swell, clean conditions are just a tease. The first few days are a total blank, and the whole 16 days is a massive gap of zero recommendations. It's a tough one.
For a spot like Zaga, a run this flat is pretty normal. It's not a place that gets consistent waves. Don't hold your breath. The forecasts can always change, but right now, your best bet is to find something else to do. If you're desperate, a kite might be more fun than a surfboard on a flat day, but even then, the wind is mostly light.
