The Lowdown
Alright folks, Rusty here. Let’s get real about the stretch ahead. The forecast is a tough one – there’s a long, dry gap with no real surf on offer from now until the morning of the 12th of August. That’s almost a full week of flatness. The only break on the radar is Zaga (Koroni), and it’s a rare beast that barely wakes up. The water is sitting at 80.6°, which is about a degree and a half warmer than usual for this time of year – a nice, warm bath.
The first real flicker of life comes on the morning of Wednesday, 12th August. We’re looking at a tiny 0.3ft swell out of the SE with a period of just 4 seconds. The combined energy is a measly 1 (weak). It’s not much to write home about, but there’s a light NNW cross-offshore breeze and the phrase “clean” pops up. For a spot that rarely breaks, seeing any pulse at all is a small miracle. The waves will be tiny, gutless, and only for the absolute beginner or a longboarder desperate for a paddle.
Morning of Thursday, 13th August, offers a repeat: 0.3ft SE swell, 4-second period, energy still at 1. The wind is a light N offshore, keeping it glassy clean. Again, it’s wafer-thin, but it’s rideable for the foamie crew.
The week after that stays in the same rut. There’s a peek of glassy conditions with 0.3ft SE swell on the morning of Saturday, 15th August, and then a 0.7ft SSW swell on the afternoon of Thursday, 20th August. The 20th has a bit more energy at 3, but it’s still a micro-swell with a 4-second period, so don’t expect any push. The winds are light and variable, often glassy or cross-off, which is the only saving grace.
Honestly, there’s no standout session here. The best on offer is the morning of the 12th or 13th of August. If you’re a total beginner and you just want to feel a tiny wave under a clean sky, you might get a wobbly knee-high slide. For anyone else, this is a flat spell. Don’t hold your breath – this area tends to go quiet like this, so it’s not a surprise. Fingers crossed the forecasts change.
