The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks.
Mate, I’ve gotta be straight with you – it’s a bit of a tough stretch ahead for Zaga (Koroni). The forecast is looking pretty flat for the majority of the 16-day window. We’re talking about a long, dry spell with no real surf to speak of until the 11th of August, and even then, it’s barely a whisper. After that, it’s back to the same old story. The water’s sitting at about 81°, which is a touch warmer than usual for this time of year, so at least the swims will be nice.
Let’s break it down. From now until the 10th of August, there’s absolutely nothing. Zero energy. The combined swell energy is a big fat zero (0). It’s going to be a total write-off. You’ll be looking at a glassy, flat lake.
The first hint of life comes on the morning of Tuesday, the 11th of August. We’ve got a tiny 0.3ft swell rolling in from the SE with a short period of 4 seconds. The combined energy is a paltry 1. It’s so weak it’s barely a ripple. The wind is a moderate cross-offshore breeze from the north, so it’ll be clean, but with that little energy, it’s not going to be surfable. The 12th of August is just as bleak, with a 1.0ft, 2-second period swell from the SSW. That’s not much more than a bump.
From the 13th of August right through to the end of the window on the 20th, we’re back to zero for the swell. There are some glassy mornings on the 16th, 17th, and 18th, but with no swell, it’s just a perfect mirror. The afternoon winds pick up, but there’s nothing to push.
Overall, there’s not a single standout session here. This is a classic blank run for this area. Sometimes it just goes quiet. The only thing I can say is that the water is warm and the mornings are calm, so if you’ve got a longboard and a lot of patience, you might catch a ripple, but honestly, don’t hold your breath. Forecasts can change, so keep an eye on it, but for now, I’d be finding something else to do.
