The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s ahead for Agios Ioannis. Gotta be straight with you – the next couple of weeks are looking pretty flat and ordinary for this spot. There’s a long, quiet spell on the cards, so don’t get your hopes up too early.
We’re looking at a stretch from the start of September right through to the middle of the month with barely a ripple. The water temp is sitting about average for this time of year, which is nice, but the swell is tiny. For the first week, we’re seeing waves barely cracking 0.7ft to 2ft, coming from the ENE with a short, weak period of only 4 to 6 seconds. The combined energy is weak, often in the single digits or low double digits (2 to 102). The wind does offer some clean, glassy moments, especially on the morning of the 2nd and the afternoon of the 3rd, but with no real swell to work with, it’s just a flat, pretty ocean. A few afternoons get a bit choppy with cross-onshore breezes, but there’s nothing to surf.
There’s a big gap with no real recommendations. We tick over into the second week with more of the same – small, weak ENE swells, mostly 1ft to 3ft, and still poor surf conditions. The combined energy climbs a little but stays moderate at best (up to 171). The morning of the 9th is a tease, with a 4ft swell and glassy conditions, but the energy is still moderate (171) and the period is short, so it’s more of a messy ankle-snapper than a proper wave. After that, it’s back to flat or tiny, choppy stuff.
Now, the one that’s got me talking is the session on Thursday, September 17th. That morning, everything finally clicks. We’ve got a 6ft groundswell from the ENE, with a period of 7 seconds, pumping in with strong wave energy (525). The wind is glassy – a light offshore from the WNW – and the forecast says expect very good surf conditions. This is the standout. For a point break like Agios Ioannis, that ENE swell direction is close to the optimum, and with clean, offshore winds, it’s going to be seriously good. This one is for the experienced crew, though – at 6ft, it’s not for beginners.
So, hang tight, keep that board waxed, and mark your calendar for the 17th. It’s a long way out, so the forecast could shift, but right now, that’s the day to be ready.
Rusty.
