The Lowdown
Alright, I’m Rusty. Let’s talk about Agios Ioannis over the next couple of weeks.
Honestly, it’s a pretty quiet stretch. There are long gaps with pretty much nothing to ride. The first real chance to get wet doesn’t come until Friday the 14th. The first few days are just tiny, weak dribbles – combined swell energy is only 2, so it’s barely a ripple.
Friday morning the 14th is the standout. The swell picks up to about 7ft from the ENE with a period of 8 seconds, and the combined energy hits a moderate 978 – that’s the biggest push we’ll see. The wind is onshore from the NE at 6 mph, so it’ll be a bit bumpy, but it’s still the best option. This break is a point, and the direction isn’t perfect (it prefers NE), but the size will make it work. Water temp is about average for this time of year.
The rest is pretty grim. Thursday the 13th has tiny 3ft waves in the morning and 3ft in the afternoon, but the wind is cross or cross-on, and the energy is low (58 and 93). Saturday the 15th has 5ft in the morning, but again the cross-on breeze kills the quality. Sunday the 16th morning has a glassy window with 3ft waves, but the energy is weak (135) – ordinary at best. That’s about it.
From Sunday afternoon onward into the second week, it flatlines. From the 17th to the 25th there’s a long stretch of flat to tiny junk – less than 1ft – with no energy. On the 25th afternoon a little 3ft pulse shows up from the NNW with glassy conditions, but the energy is only 46 – a very weak set. The 26th morning is similar with 3ft and offshore wind, but the energy is still low (64). Not worth chasing.
So, if you’re keen, Friday the 14th morning is your best bet. Otherwise, it’s a long wait for anything worthwhile. This is a quiet spell for Agios Ioannis.

A general guide to surfing at Agios Ioannis can be found by selecting the local surf guide option on the grey menu. Our Agios Ioannis surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
