The Lowdown
Alright folks, Rusty here. Let’s get straight into it for the local stretch.
Right off the bat, I gotta be honest with you – this is a tough one. The whole 16-day window looks like a total dud for any proper surf. The first real recommendation doesn't come until the very end of the period, and even then, it's a whisper. We’ve got a long stretch of flatness ahead, with combined swell energy sitting at zero (0) for almost every day. That’s about as dead as it gets.
The only break on the cards is Zaga (Koroni). Now, this place is a sheltered beach and point setup that rarely breaks, so a blank run like this is more normal for the area than you’d hope. The water temperature is clocking in at 81°, which is a couple of degrees warmer than usual for this time of year – a real anomaly that's much warmer than normal.
Looking at the first real flicker of hope, we have to jump all the way to Friday the 24th of July. The afternoon shows a tiny 1ft swell from the SSW with a short period of 3 seconds, and the wind is howling offshore from the WNW at a strong 25 mph. The combined energy is a measly 5. That's not surf, that's just wind chop. It's clean, but practically impossible to paddle into with that period. After that, it’s back to nothing but flat, clean, glassy mornings with no swell at all.
The only other tiny pulse shows up on the morning of Wednesday the 29th of July – a 0.3ft, 5-second swell from the SW. Combined energy of less than 1. It’s not even worth mentioning as a wave. The offshore winds through this period are a saving grace for the scenery, but they can't make waves out of nothing.
The best bet – and I use that term loosely – is that Friday the 24th of July. The winds are strong offshore and clean, but the swell is non-existent. For a beginner spot, this is a total washout. For anyone else, it’s a flat spell. The setup honestly looks more interesting for kite surfing than paddle surfing if you’ve got the gear, but for a surfer? Save your energy.
Rusty.
