The Lowdown
Alright, I’m looking at the charts for the Agios Ioannis zone and I gotta be straight with you – it’s a pretty quiet stretch ahead. The whole 16-day window is a tough one. There’s not a single standout wave day in there, but let’s walk through what’s going on.
The water temp is sitting at about 80°F, which is a touch warmer than usual for this time of year – not a game-changer but nice if you’re in a shorty.
We start off today, Wednesday the 19th, with nothing doing – flat and clean but no swell energy to speak of. Thursday the 20th is a little bit of the same: Thursday morning is glassy but still no waves, and by the afternoon we see a tiny 0.7ft from the ENE with a 3-second period and combined energy of just 1 (weak). That’s barely a ripple. Friday the 21st offers a morning glass-off with a 1ft NE swell at 4 seconds and energy of 4 – still poor. The afternoon picks up a little to 2ft from the ENE at 5 seconds and energy of 15, but it’s cross-onshore and messy.
Saturday the 22nd is the “biggest” day in the first week with 2ft from the ENE at 6 seconds and combined energy of 33 (still weak). The wind is cross-onshore though, so the surface is choppy. Not the kind of day you paddle out for.
From there, the pattern holds: small, weak, poor surf all the way through the end of August. Mornings are often glassy or light, which is nice, but there’s just no push. The swell stays tiny – mostly under 2ft – and periods are short, under 6 seconds. The combined energy rarely breaks past 20. It’s a persistent flat spell.
We get a few glimmers toward the very end. On Monday the 31st of August, the morning glass-off with a 2ft ENE swell at 4 seconds and energy of 10 isn’t much, but it’s clean. Then on Thursday the 3rd of September, the afternoon shows a 3ft from the NNW at 4 seconds with energy of 21 and glassy conditions – that’s actually the best looking window in the whole forecast. Still, 3ft and 4 seconds is weak and short-period, so don’t expect much shape.
Honestly, Agios Ioannis is a point break that’s inconsistent to begin with, and this forecast confirms that. There’s simply no real swell energy coming through. If you’re desperate for a splash, the cleanest windows are Thursday morning the 20th, Friday morning the 21st, and Monday the 31st of August morning, but the surf is barely rideable. The only window that shows a pulse is Thursday the 3rd of September afternoon – but even that’s marginal.
Right now, it’s a waiting game. The break is inconsistent, and when the swell is this small, it just doesn’t fire. Forecasts can change, but for now, keep your board in the car and your expectations low.

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.

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.
