The Lowdown
Alright, I’m Rusty, and I’m looking at the next couple of weeks here at Agios Ioannis. It’s a right-hand point, known for needing a bit of a push, and it’s inconsistent at the best of times. Right now, we’re in a flat spell that just won’t quit.
To be honest, the first stretch is a real struggle. From Monday the 17th all the way through to the end of the month, the wave energy is just not there. We’re seeing tiny 0.7ft to 1ft slop, with swell periods of 4 seconds or less, and the combined energy is barely registering – under 5 (weak energy). It’s a quiet, glassy morning or two, but there’s nothing to paddle for. The water temperature is sitting at 80°, which is a touch warmer than normal for this time of year, so the water’s nice, but the waves are missing.
There’s a stretch of absolutely nothing from the 19th right through the 25th – multiple days in a row where the forecast shows zero or near-zero energy. It’s a long, dry run.
Then, around Wednesday the 26th, we finally see a little pulse. It’s still marginal, but the combination of a 2ft ENE swell with a 4–6 second period, and a wave energy that climbs to 55 (weak), at least gives us something to look at. The morning of the 26th is clean, with a light offshore wind from the NW, making it look glassy. Still, it’s barely breaking.
The most standout window is Thursday the 27th in the morning. Swell height jumps to 5ft from the ENE, with a period of 7 seconds, and the combined energy hits 389 (moderate). The wind is NW at 15 mph, blowing cross-offshore, keeping the waves clean. That’s the best we’re going to see in this whole 16-day forecast. It’s a decent-sized swell but nothing too crazy, and it’s well suited for the point. The optimum swell direction for Agios Ioannis is from the NE, and this is coming from the ENE, so it’s close enough to get some good wraparound. This is a standout – but it’s a one-off.
After that, it fades fast. The 28th of August and the weekend that follows drop back down to tiny, choppy conditions with onshore winds. By the 1st of September, we’re back to 1ft slop with more cross-onshore breeze.
So, if you’re after the best of a bad run, set your alarm for Thursday the 27th of August morning. That’s the only morning that looks worth a paddle. The rest of the window is a write-off.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
