The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days at Agios Ioannis are looking pretty grim. We’ve got a long stretch of tiny, weak swell and mostly onshore or cross-onshore winds that are going to keep things flat and bumpy. There’s a big gap of several days right at the start where you’d be better off doing something else, and then a long, drawn-out period of nothing much to get excited about. The best we can hope for is a couple of marginal mornings that might just be worth a look if you’re desperate.
The water is sitting at a very warm 82°F, which is a solid 6°F warmer than usual for this time of year. That’s pretty unusual, so you won’t need a wetsuit, just a good dose of patience.
Let’s run through it. The forecast kicks off Monday the 7th of September with a tiny 1 ft swell from the ENE and a weak 4-second period. The combined energy is a measly (6), and the wind is light from the NE, which is actually onshore here. It’s a no-go.
Tuesday the 8th sees a slight bump to 4 ft from the ENE, but the period is still a short 6 seconds, and the wind is cross-onshore from the east. The energy picks up to (116) but the conditions are poor. Not worth paddling out.
Wednesday the 9th morning is the closest we get to a recommendation. The swell is 3 ft from the ENE, period still 6 seconds, and energy is (132). The wind is a light cross-onshore from the east, which leaves some small ripples. It’s just a marginal, ordinary day. The best of a bad bunch, but honestly, it’s not a standout.
For the rest of the first week and into the second, it’s a slow fade. The swell drops back to under 3 ft, the period stays short, and the winds are mostly cross-onshore or glassy but with zero energy. Saturday the 12th morning has a glassy 3 ft wave from the ENE, but with a 5-second period and energy of just (51), it’s surfable but very ordinary.
From the 13th of September onwards, the writing is on the wall. The swell collapses to tiny 1.0 ft or 1 ft waves, period drops to 3 or 4 seconds, and energy figures are in the single digits. The wind goes through phases of being glassy, cross-onshore, and even a strong NNW breeze on the 20th that brings a messy cross-chop. There’s nothing here to pull on a wetsuit for.
The 21st and 22nd of September are the last days in the window, and they’re a write-off. A tiny 0.7 ft wave from the east with a 4-second period on the 21st, and a 0.3 ft wave on the 22nd. The energy is 2 or less. Forget it.
The deeper swell from the north on the 20th might look interesting on paper, but with a 3-second period and a strong cross-shore wind, it’s a messy, choppy mess. This setup is more interesting for kite surfing than paddle surfing.
So, in short, the whole 16-day window is a dud. No standout days, no clean groundswell. Just a lot of waiting. Forecasts can change, but for now, the board stays in the car.
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.

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.
