The Lowdown
Alright, Rusty here again, looking at Agios Ioannis for the next couple of weeks. Gotta be honest – it’s a total bust for surf.
The whole 16-day forecast is a flat, empty stretch. There’s a big gap with no real surf at all. The first few days are completely flat, and even when a little pulse shows up, it’s not worth paddling out for.
The only time the ocean even tries to wake up is around the 8th and 9th of September. On Tuesday the 8th, we get a combined swell energy of (131) – that’s moderate – but it’s only a 4ft swell from the ENE with a short period of 6 seconds. That’s weak, windswell junk. The wind is cross-onshore from the east at 6 mph, so it’s choppy and messy. It’s a beach-and-reef setup, but with that poor quality and wind, it honestly looks more interesting for kite surfing than paddle surfing. The next day, Wednesday the 9th, has a similar 4ft ENE swell, but even stronger cross-onshore wind at 12 mph, making it a full-on choppy mess. Not for beginners – that size is okay for intermediates, but the wind ruins it.
The water is warm at 81°, which is much warmer than normal for this time of year – that’s a notable anomaly of nearly 5° above average. Feels like a hot tub, but the waves are the problem.
Outside of those few days, it’s flat or near-flat with glassy or light wind conditions, but no swell to ride. The whole period is a dud. This spot is inconsistent, and this run of blank days is more normal for the area. Keep your hopes low, and check back – forecasts can change, but this one’s a washout for now.
Rusty.

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.
