The Lowdown
Alright folks, Rusty here. We’ve got a pretty grim picture for the next two weeks. Let’s break it down.
Right off the bat, I’ll tell you straight: there’s nothing to get excited about. The first real chance of a wave doesn’t show up until Wednesday, September 9th, and even then, it’s a whisper. We’re looking at over a week of flat, clean, but totally unsurfable conditions. From now through Tuesday, September 8th, the ocean is basically a pond. You’ll see glassy mornings and clean afternoons, but with zero swell energy (0 for combined energy), you’re just paddling for nothing.
The only spot on the radar is Zaga (Koroni). This is a sheltered beach and point setup that’s a beginner spot, but it rarely breaks. We’re about to see exactly why. The water here is running at 83°F which is much warmer than normal for this time of year, a solid 4°F above average.
The first tiny pulse comes in on Wednesday morning, September 9th. We’re talking a 0.3ft swell from the SE with a short period of 4 seconds. The combined energy is a pathetic 2, so you’re basically looking at a ripple. That morning, the wind is offshore from the NNW at 6 mph, so it’ll be clean but tiny. In the afternoon, the wind swings to WNW at 12 mph, still offshore, and the swell bumps up to 0.7ft from the SSE. That’s still not enough to push a leaf.
After that, it’s back to flat nothing. The rest of the second week is a write-off. There’s a tiny blip on Tuesday, September 15th, with 0.3ft from the SE and a 4-second period, but it’s onshore wind from the SSE at 6 mph, with a risk of thunderstorms. Not worth even looking at. The same goes for the morning of Wednesday, September 16th.
Honestly, for a spot that rarely breaks, this is a textbook dry spell. The setup is more interesting for a kite than a paddle board right now. Don’t waste the petrol. Forecasts can always change, but this is a long, bleak run.
Rusty.
