The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve looked over the next couple of weeks, and it’s a tough one. We’re staring down a long stretch of flat, poor conditions with no real swell to speak of. So let’s just get into it.
The outlook is grim for the foreseeable future. The first recommendation doesn’t even show up until the 19th of August, and even then, it’s a no-go. We’re looking at a solid run of days with zero surf potential. The energy in the water is essentially non-existent, with combined energy values sitting at a weak 1, and that’s being generous. The winds are variable, but it doesn’t matter much when there’s nothing to push around. You’ll see some clean, glassy mornings and some offshore breezes, but it’s all for nothing with a flat ocean. It’s just a bummer.
The best we can hope for is a tiny blip late in the window. Around the 27th of August, there’s a hint of life, but it’s pitiful. We’re talking about a 1 ft swell coming from the southwest with a period of just 2 seconds. That’s not surf, that’s a ripple. It’s not even worth getting your board wet for. The 28th of August morning shows a 0.3 ft southeast swell, period of 4 seconds, which again, is nothing. The 2nd of September rolls around with a similar 0.3 ft southeast swell in the morning and a 1 ft southwest swell in the afternoon, but the period is still a pathetic 2 seconds. These short-period, tiny swells are not going to break properly at Zaga (Koroni). It’s a beach and point break, and with no energy, it’s just going to be a lake with a slight breeze.
Now, even if we did get some size, this spot rarely breaks. It’s a sheltered spot, and it’s just not picking up any of the directional swell it needs. It’s a beginner spot, but with no waves, it’s not even good for that. The only positive I can find is that the winds are often offshore or glassy, which is great for keeping the surface clean. But it’s like polishing a car with no engine. All show and no go.
So, my honest take: there are no good surf options in this 16-day window. It’s a complete blank. For an area that’s this inconsistent, a run like this isn't surprising, but it doesn’t make it any easier to swallow. We’ll just have to wait for the ocean to wake up. Forecasts can change, but for now, keep the boards in the garage.
Rusty, out.
