The Lowdown
Alright folks, Rusty here. Let’s get straight into it. I’ve got the goods on the local surf outlook, and I’ll be honest with you: it’s a tough one for the next couple of weeks.
We’re looking at Zaga (Koroni) – a beach and point setup that’s sheltered and rarely breaks. And true to form, the next 16 days are virtually a flat spell. For the first several days, there’s nothing to get excited about. The combined swell energy is a flat zero (0) for most of the period. There’s a brief moment on Monday the 8th of September afternoon where we see a tiny 1.0ft swell from the SW, but with a period of only 3 seconds and cross-shore winds at 12 mph, it’s messy and weak. The combined energy is just 3 – that’s barely a ripple. Then again on Monday the 15th of September afternoon, a 1ft SE swell shows up, but again, period is a short 2 seconds and the wind is cross-shore at 12 mph. The energy is only 2. These are not surfable conditions for anyone.
The water temperature on Monday the 7th of September morning was 84°, which is a whopping 7° warmer than usual for this time of year. That’s very unusual – the water is much warmer than normal, but it’s not doing us any favours with the waves.
Given the lack of any real swell, there’s no standout break to highlight. The entire 16-day window is a gap of poor surf conditions. There are no true standouts on offer. For a spot that rarely breaks, this kind of blank run is pretty normal. It’s just one of those stretches where the ocean is having a nap.
Hang in there, and keep an eye on the charts – it tends not to stay this poor forever.
Rusty.
