The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window is a tough one for our region. We’re looking at a long, dry spell with hardly any swell to speak of. The first real chance of anything rideable doesn't show up until Thursday the 23rd of July, and even then, it's barely a whisper.
Let’s break it down. From now until the 23rd, there’s a big fat zero on the energy scale. The water is currently sitting at a very unusual 82°, which is a whopping 5° warmer than normal for this time of year – feels like bathwater, but not a lick of surf to enjoy it in.
Now, Thursday afternoon the 23rd at Zaga (Koroni) is where we finally see a pulse. A tiny 1.0ft southerly swell is forecast, but with a period of only 2 seconds, it’s got no push. The combined energy is a pathetic 1 (1). On the bright side, we’ll have a gentle offshore wind from the WNW at 9 mph, keeping the surface clean. But honestly, this is a spot that rarely breaks, and for good reason. It’s sheltered and needs a very specific SSE swell direction to work. This little southerly bump won’t cut it for a proper wave.
The rest of the outlook is more of the same. We go from the 23rd all the way to the 1st of August with nothing but zeros. On the morning of the 1st of August, we get another tease: a 0.3ft southeasterly swell with a 4-second period. Again, the combined energy is a measly 1 (1). The wind will be glassy from the NNW, but that’s it. Another day of clean, flat conditions.
The pattern is persistent. This area just isn't seeing any significant swell in this forecast. For a spot that’s already inconsistent, this is a pretty normal blank run. If you’re desperate for a paddle, you might find a knee-high ripple on those two afternoons, but it’s not worth getting excited about. The setup here is more interesting for a kite than a surfboard, given the long gaps of nothing.
Stay patient, folks. Forecasts can change, but this one looks like a long one.
Rusty.
