The Lowdown
Alright folks, Rusty here. Let’s get into it. I’ve got the full 16-day picture for you, and honestly, I’m struggling to find the silver lining.
We’re looking at a long, dry spell with no real surf to speak of for the entire forecast period. The first weather window from July 21st right through to August 5th shows zero wave energy – the combined swell energy is a flat 0. What that means is there’s simply nothing breaking. The only spot with any pulse in the water is Zaga (Koroni), but don’t get your hopes up. This is a beach-and-point set-up that rarely breaks, so a blank run like this is more normal for the area than unusual.
The one tiny flicker of hope comes on Saturday, July 25th, in the afternoon. We finally see a little bump: a 1.0ft swell rolling in from the south with a period of just 2 seconds. That’s basically wind chop, not a real swell. Combined energy is a pitiful 1. The wind swings to a moderate cross-shore from the SSW at 12 mph, which will just make it messy. Honestly, that setup looks more interesting for kite surfing than paddle surfing. If you’re a beginner, stay away – this isn’t worth the paddle.
For the rest of the run, from July 21st through to August 5th, it’s a similar story. We see glassy mornings, clean offshore breezes, and even some gentle offshore winds, but without any swell to push through, it’s just a flat, pretty lake. The water temperature on July 21st morning is a warm 82°, which is 5° warmer than normal – very unusual for this time of year. But that’s about the only notable thing.
Honestly, this is a tough one. It’s a 16-day flat spell. The forecast might change, but as it stands, there’s nothing to recommend. No standouts, no hidden gems. Just wait for the next swell.
Rusty.
