The Lowdown
Alright, Rusty here, let's take a look at what we've got coming up at Agios Ioannis.
Right off the bat, I gotta be straight with you – this 16-day window is looking pretty grim. We've got a long stretch of flatness and poor conditions with only one real moment that's worth paddling out for. Get ready for a lot of lake-like conditions before we see any energy.
The only decent surf on offer hits us on Sunday, August 16th, in the morning. We're looking at a 5ft swell rolling in from the ENE with a period of 7 seconds. It's a bit of a short-period windswell, so don't expect any real groundswell power, but the combined energy is sitting at 339 (moderate wave energy). The wind is absolutely perfect though – glassy, 3 mph from the ENE – so those waves will be clean as a whistle. For a point break like Agios Ioannis, a short period like that can still offer up some fun, shaped-up lines, especially with no wind chop. It's an inconsistent spot that breaks best when the swell is from the NE, and this ENE swell is close, but not quite bang on optimum. Still, for the conditions, it's the standout. Just be aware it can get crowded here sometimes.
After that Sunday morning window, it's basically a write-off. The surf disappears to tiny, ankle-to-knee high dribble, and the wind turns onshore or cross-shore for the rest of the period. A few glassy moments pop up on Thursday the 20th and Monday the 31st, but with swell heights of 0.3ft to 2ft and almost no energy (1-13 combined energy), you’d be better off going for a swim. The water temperature anomaly is within the normal range for this time of year, nothing to write home about.
So, the call is simple: If you can, hit it on Sunday morning the 16th. After that, it's a long dry spell of 14 days with nothing surfable on offer. Keep an eye on it, forecasts can shift, but right now, it's a one-session window.

Information about the Agios Ioannis Surf forecast
The above surf forecast table for Agios Ioannis provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Agios Ioannis) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
