The Lowdown
Alright, let’s get this straight. The next couple of weeks are looking pretty grim for decent waves at Agios Ioannis. There’s a whole lot of small, weak, and short-period swell on the horizon, and frankly, not much to get excited about. We’re going to have a long stretch of nothing before we see anything rideable.
The first real glimmer of hope doesn’t show up until Friday the 14th. Early that morning, we’re finally looking at some proper energy. The swell bumps up to 6ft from the ENE, and the period is a lackluster 7 seconds. The wind is glassy, which is a huge plus. The water is a balmy 82°F, which is 5°F warmer than normal for this time of year – that’s a big deal, the ocean is properly warm. The combined energy reading is strong at 647, so there’s some push behind it. This is the standout of the whole period. It’s not perfect, but it’s the best we’re going to get. The swell direction is straight onshore, but that glassy morning will make it the cleanest it’ll be all week. This is your window.
The weekend after that, the 15th and 16th, will see the swell hanging in there, but the wind is going to be a problem. Expect choppy, cross-onshore conditions that will mess up what could be a decent wave. The energy is still moderate, but the quality will be poor to marginal at best.
After that, it just fades away. From the 17th onward, the forecast is a wasteland of tiny, weak, and short-period leftovers. We’re talking ankle-biters with no power. The swell energy drops off a cliff, and we’re back to the same old story. The rest of the week and into the next is just flat and grim. There’s nothing on the table that’s worth paddling out for.
So, to be straight with you: there is one morning worth circling on the calendar, and that’s Friday the 14th. Get up early, enjoy the warm water and clean conditions, and get what you can. Beyond that, it’s a long dry spell.

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.
