The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
Honestly, I’ve got to be straight with you – this is a tough one. For the whole 16-day window, there’s just no surf to get excited about. The only break on the cards, Zaga (Koroni), is a sheltered little number that rarely breaks anyway, and this stretch proves it out. The water temp is sitting at 83°F right now, which is much warmer than normal for this time of year – a solid 4°F above average, so it’s like a bathtub out there, but that doesn’t help with the waves.
From this Sunday, August 16th, right through to Monday, August 31st, it’s a flat spell. There’s a tiny hiccup of swell on the very first morning – just 1ft from the SW with a period of 4 seconds. Swell energy is a measly 2, which is about as weak as it gets. The wind is light offshore from the NNW, so the surface would be clean, but with that kind of size and period, you’d be bobbing around on ripples, not waves. After that, the rest of the forecast shows nothing – zilch, zero surf for 15 days straight. There are some glassy mornings and offshore breezes scattered through the period, like the 19th, 20th, and 27th, which would be beautiful if there was a wave to ride, but there isn’t.
This kind of blank run is pretty normal for Zaga, it’s not a spot that sees much action. If you’re a kiter, the fresh offshore winds on the 29th and 30th might get your attention, but for paddle surfing, it’s a no-go. Keep an eye on the charts, though – it tends not to stay poor for long around here.
Rusty.
