The Lowdown
Alright, folks, let's talk about what's on the table for Agios Ioannis. I'm not gonna sugarcoat it.
Right off the bat, we've got a long, quiet stretch ahead. The good news? It’s not going to stay flat forever. The bad news? For the next couple of weeks, this point break is going to be mostly a flat lake.
We start with the 5th of September, and honestly, it's a bust. You’ve got tiny knee-high waves at 0.7 ft from the east with barely any energy (1). The water is a very unusual 82°F, which is much warmer than normal for this time of year, but that’s about the only excitement. Saturday and Sunday of the 6th and 7th have a little bit of movement, but with swell under 2 ft and periods around 4-5 seconds, it’s wind swell mush.
That pattern pretty much holds all the way through to the 19th of September. We’re looking at tiny, weak swells mostly from the ENE, with combined energy figures barely tickling double digits. The wind is cross or cross-onshore more often than not, keeping things choppy. There’s a brief moment on the morning of the 12th and again on the 19th where it goes glassy, but with zero swell, it doesn’t matter.
Alright, now let's get to the only real flicker of hope. It comes in the second week, on the 20th of September. Sunday morning we see a pulse of 4 ft swell from the ENE with a period of 6 seconds. The combined energy jumps to 199 – at least it’s something. But here’s the kicker: the wind is showing as cross-offshore from the northwest. That's clean, that’s promising. And then the afternoon turns glassy, with the swell still hanging at a solid 4 ft from the ENE and energy at 182.
It won’t be a world-class day, but for a spot that’s been dead for days, that Sunday the 20th is your best bet. The crowd factor here is "sometimes," so you might have company, but that clean glassy afternoon is a rare treat. Just keep in mind this is a point break, and with that 6-second period it won’t be a long-period groundswell, just a decent little windswell that should offer a few fun ones. Anything over 5 ft is getting big for beginners, so this 4-4 ft range is right in the sweet spot for intermediates.
So, to sum it up: you wait, you wait, and then you paddle out on the 20th.
