The Lowdown
G’day, Rusty here. I’ll level with you, it’s a rough stretch of calendar to be a surfer. We’re looking at a long, flat patch for the better part of a fortnight. Nothing to do but shake your head and check the horizon.
The first week and a half is a total write-off. We’re talking no swell, and what little kicks up is messy, short-period churn from the east. You’d be fighting the chop more than riding a wave, and honestly, it’s not worth the paddle. The only thing that breaks the monotony is a tiny pulse on the morning of the 27th. It’s a small window, but it’s a window.
Sunday the 27th is it. Zaga (Koroni) is the spot. It’s a beach and point break, and it’s one of those rare ones that only breaks sometimes. The swell direction is from the SE, and despite the size being nothing to write home about, the glassy morning conditions will make it look better than it is. The combined energy is only 33, so it’s pretty weak. It’s an easy, small wave for the beginners to have a paddle on, but it’s not going to show you the light. The water is 28°, which is a massive 4° above average for the season—a real bathtub moment, but doesn’t change the fact there’s no push.
After that, it’s back to nothing. The swell is gone by lunch, and the rest of the run is small, weak, and choppy. By the 30th and 1st we’re looking at strong onshores hitting 25 km/h and some rain, so you can take the board off the roof and leave it there. If you see anyone on a kiteboard, that might be more interesting than a surfboard.
Overall, this is a lean run. The one tiny window is on the 27th, and it’s for beginners who just want to get wet. For anyone else, it’s not worth it. But hey, this area doesn’t stay this flat for long, so I’m holding out hope for a change in the pattern. Until then, you’re on land.
Rusty.
