The Lowdown
Alright folks, Rusty here. Let's be straight with you about Agios Ioannis. We've got a 16-day window, and I'm looking at a long, quiet spell ahead. The surf's gonna be pretty flat or just plain poor for the vast majority of this forecast. There's a distinct gap in any sort of worthwhile surf until we get towards the very end.
Looking at the whole picture, this is a tough run for a point break that needs a decent push from the NE. For the first couple of weeks, we've got tiny swell mixing with mostly onshore or cross-onshore winds. The water temp is sitting about average for this time of year, nothing weird going on there. The combined energy readings are mostly in the single or low double digits—weak energy or even lower, with a few barely registering. It just isn't doing anything.
Monday morning, August 24th, starts off with glassy conditions but only 2ft of weak, short-period ENE swell at 4 seconds. That's not enough to get excited about. The afternoon wind swings onshore, making it even worse. This pattern pretty much holds right through to the end of the first week and into the second. You'll see some mornings with clean, glassy faces, but the swell is missing—1ft, 0.7ft... it's flat. The afternoons are consistently ruined by a sea breeze. Thursday the 27th morning has a glassy 2ft but the period is only 5 seconds, so it's weak and fat. The combined energy is only 34, so you can feel how limp it is. There is simply no wave energy to work with.
This flat spell drags on. The 31st morning has zero swell, and September starts the same way. You get a few more glassy mornings in the first week of September, like the 2nd, with 2ft, but it's just not enough. The afternoon chop kills it.
The only real change I can see is on Sunday morning, September 6th. We finally get a bump in swell to 4ft from the ENE, with a combined energy hitting 123 (moderate wave energy). The period is still only 6 seconds, so it's a choppy windswell, not clean groundswell. But here's the kicker: the wind is a fresh cross-shore from the NNW at 19 mph. That's howling. For a point break setup, that's messy and poor. It might look a little more interesting for kite surfing than a paddle session on that morning, to be honest. After that, it drops back to tiny on the 7th and 8th.
So, what's the standout? Truthfully, there isn't a proper standout session in this whole forecast. We don't even get a swell direction that matches our optimum (NE). The best you can hope for is a tiny, glassy morning like Thursday the 27th or Wednesday the 2nd of September, where you can have a 2ft or 2ft wave to yourself with no wind. But that's survival surfing, not the classic Agios Ioannis point experience. The crowd situation is "sometimes", but honestly, with this lack of swell, you won't have to worry about anyone else out there.
Rusty.

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).
Further information to help with frequently asked questions about our surf forecast for Agios Ioannis may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
