The Lowdown
Righto, I’m Rusty. Let’s talk about what’s on offer.
Well, to be straight with you, the next week and a bit is a total washout for any kind of wave riding at Zaga (Koroni). From now through the end of August and right into the first week of September, every single session is showing no swell at all – a big fat zero. You’ve got a solid stretch of 11 or 12 days where there’s just nothing to work with. The water is sitting at a very warm 83°F, which is much warmer than normal for this time of year, but that’s about the only good news. You’ll see some glassy calm mornings here and there, but without any swell, it’s just flat.
We finally get a tiny flicker of hope on Saturday morning, the 5th of September. A little 0.7ft SSE swell rolls in, but that’s barely enough to push a ripple, and with a period of only 3 seconds, it’s just wind chop, not surf. The combined energy is a weak 1, so it’s tiny. Winds will be offshore from the NW, so it’ll be clean, but you’re looking at knee-high slosh at best. This break is sheltered and rarely breaks anyway, so this isn’t a surprise. The rest of that day and the following days stay flat again. Honestly, for the whole 16-day window, there are no real standouts. If you’re desperate for a paddle in clean, flat water, a Saturday morning glass-off is your only hope. For any actual surfing, it’s a blank run – which is a normal deal for this spot.
Rusty.
