The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our stretch of coast.
Right off the bat, I’ve got to be straight with you – the next couple of weeks are looking pretty flat for Agios Ioannis. We’re looking at a long stretch of nothing much at all, with a real gap in any decent surf from now until around the 27th of August. That’s over a week of small, weak, and frankly poor conditions. The combined energy sitting at (0) for most of those days tells the story – it’s basically a lake out there.
The first real glimmer of anything worth paddling out for comes on Thursday morning, 27th August. The swell is tiny at just 3 ft from the ENE, but the wind is a clean cross-offshore from the NW at 9 mph. That’ll keep the surface nice and smooth. The water is a touch warmer than normal for this time of year, sitting at 80°, which is a nice bonus. It’s not going to be a classic, but the combined energy is a modest (53) and the conditions will be clean. The afternoon glass-off with the wind dropping to 3 mph from the north and going glassy is also worth a mention for a late session on the same tiny swell. Just don’t expect much push.
After that, it’s back to the usual small stuff. The morning of Saturday, 29th August is glassy, with a tiny 1 ft from the NE. The combined energy is a paltry (8). It’s surfable, but only just.
Looking further out, the beginning of September gets a bit windy. The morning of Tuesday, 1st September has a fresh cross-shore wind at 19 mph, which will make things lumpy, and the swell is basically non-existent. The combined energy is (1). It’s not looking like a great time to be out there.
To be honest, the standout window here is the Thursday 27th of August. The swell is small, but the clean, glassy conditions in the afternoon will make it the most pleasant paddle of the whole forecast. The swell direction is ENE, and while the spot is exposed and the optimum swell is from the NE, it's close enough to work. Don’t expect any barrels, but for a quiet, peaceful surf, that’s your best bet.
Stay patient, and keep your eye on the charts.

A general guide to surfing at Agios Ioannis can be found by selecting the local surf guide option on the grey menu.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
