The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
First off, I gotta be straight with you – this is a tough one. We’re looking at a long, dry spell with basically nothing on offer for the first 12 days. From Tuesday the 21st of July right through to Friday the 31st of July, it’s a flat, dead ocean. The combined energy reading is a big fat zero. There’s no swell to speak of, just clean, glassy mornings and some cross-off breezes in the afternoons, but without any waves, that doesn’t mean a thing. It’s a frustrating stretch for anyone wanting to paddle out.
You’ll be sitting on the beach, watching the horizon do absolutely nothing. For a spot like Zaga (Koroni), which is already a rare-breaker and sheltered, this kind of blank run is more normal for the area. The water temperature is about average for the time of year, so you can’t even blame a cold snap.
Now, hold onto your board, because there is a tiny flicker of hope right at the very end. On the morning of Sunday the 2nd of August, we finally see something – a tiny pulse of swell from the SE. It’s only 0.3 ft, with a period of just 4 seconds, and the combined energy is a measly 1. That’s barely a ripple. The wind is a light cross-off from the NNW, keeping the surface clean, but this is not a wave you’re going to be riding. It’s a flash in the pan, and by the afternoon, it’s gone again.
So, what’s the call? The best on offer is that Sunday morning, the 2nd of August, but only if you’re desperate to get wet. It’s not a surfable wave, just a sign that the ocean is still alive. For the rest of the outlook, it’s a total write-off. Keep the boards in the car and the wax in the box. The forecast can always change, but for now, it’s a waiting game.
Rusty.
