The Lowdown
Alright, Rusty here. Let’s talk about Agios Ioannis for the next couple of weeks.
Right off the bat, things are flat. Like, frustratingly flat. There’s a gap at the start with nothing worth paddling for – the first few days are all ankle-biters with hardly any energy. The water is much warmer than normal for this time of year at 81°, which is very unusual, but that’s small comfort when there’s no surf.
You’ll be waiting until Friday the 14th of August before anything really registers. That morning, Agios Ioannis gets a pulse of 7ft swell from the ENE (moderate energy at 707). The wind is light cross-onshore, so it won’t be perfect, but it’s the first real sign of life. That energy hangs in through Saturday the 15th with similar size, around 7ft to 7ft, still from the ENE, still with light cross-onshore breeze. These are intermediate-level waves, pushing a bit big for beginners.
The standout, however, is the morning of Sunday the 16th of August. Glassy conditions, 5ft ENE swell with a period of 8 seconds, and combined energy of 244. That’s the pick of the whole run – clean, glassy, and a manageable size for intermediates. The only catch? Agios Ioannis is an inconsistent point break. It doesn’t fire often, so when it does, you get in the water. Crowds are possible here, so expect company. The swell direction from NE is right in the sweet spot for this spot.
Monday the 17th drops off fast – back to tiny, poor surf. After that, it’s a long, sad run of flat or nearly flat waves right through to the end of the forecast on the 24th. Wind picks up strong from the NNW on the 19th, 30 km/h (19 mph), but with swell barely 0.7ft, there’s nothing to ride. Honestly, for the second week, there’s nothing worth chasing.
So, to sum it up: the only real window is Friday the 14th through Sunday the 16th. Make the most of it. After that, you’re better off doing something else.
Rusty.

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

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.
