The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next couple of weeks look pretty bleak for a paddle. We’re looking at a long stretch of flatness with hardly a ripple to get excited about.
Right from the start on Wednesday the 5th of August, it’s a no-go. The combined wave energy at Zaga (Koroni) is a big fat zero (0), and we’ve got a 16 mph cross-offshore wind blowing across a flat ocean. The water’s a touch warmer than normal at 81°, but that’s the only comfort here. The whole first week, from the 5th right through to the 10th, is a total write-off. There’s simply no swell, just glassy mornings and cross-off breezes that do nothing for us.
We do finally see a pulse of something on the morning of Tuesday the 11th of August. A tiny 0.3 ft swell from the SE with a period of 4 seconds—that’s short-period wind chop, not a groundswell. The energy is a pathetic 1. It’s still poor surf conditions, and the wind is cross-off from the north. Not worth paddling out for.
The pattern stays stubbornly flat. A few more of these tiny, short-period bumps pop up on the 12th of August with a 1 ft SW swell (period of 2 seconds), and again on the afternoon of the 15th of August with a 1 ft SW swell (period of 3 seconds), but the energy never gets above 3. The wind is often cross or cross-off, and the wave comment is always “poor surf conditions.” This break rarely breaks anyway, and this forecast proves it.
Honestly, there’s not a single standout session in this 16-day window. It’s a classic dead spell for the area. The only positive is that it tends not to stay this poor for long, so keep an eye on the charts—things can change. But for now, leave the board at home.
Rusty.
