The Lowdown
G'day, Rusty here. Look, I've gotta be straight with you – this outlook for Agios Ioannis is a tough one. We're looking at a 16-day window that's almost a write-off for decent waves. The good news is the water is much warmer than usual for this time of year, sitting at 80°F. That's a solid 5°F warmer than normal, so it feels like a bath out there.
Let's run through it. The first couple of weeks are dry. From Saturday the 18th through to Thursday the 30th of July, it's a long stretch of flat to tiny, messy junk. We're talking swell heights mostly under 3ft, with periods so short they're barely worth paddling for. The combined energy is weak, often in the single digits or low tens (like 0 to 80). The wind is a constant problem – cross-on or onshore from the ESE or E, creating chop and ripples. There's a brief moment of glassy conditions on Tuesday the 21st morning, but no swell to go with it. It's a frustrating wait.
The first real sign of life comes right at the end of the month. On Thursday the 30th of July afternoon, we finally get a "surfable waves but very ordinary conditions" call. The swell is 3ft from the ENE with a 6-second period, combined energy 58. The wind goes glassy, which is a huge positive. It's small and weak, but at least it's clean. Friday the 31st of July morning is the best bet in this whole outlook. The swell picks up to 4ft from the ENE, with a 7-second period and combined energy of 144. The wind is glassy again. This is your best chance, but it's still just ordinary surf. The crowds at Agios Ioannis are "sometimes" an issue, and with this being a point break that's inconsistent, you might have it quiet.
The period from Sunday the 2nd of August onward shows a little more energy – 4ft swells with 161 combined energy – but the wind is a cross-shore breeze, making it messy. There's a glassy window on Sunday afternoon with 4ft and 118 energy, but it's still just "surfable waves but very ordinary conditions." Honestly, nothing here is a standout. The best on offer is the morning of Friday the 31st of July, with 4ft of ENE swell and glassy conditions. It's small, but it's clean. Don't expect barrels or power. The whole run feels like a waiting game. For a point break, the long-period groundswells we'd normally hope for are absent; these short-period, wind-driven waves won't shape up well.
Rusty.

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.
