The Lowdown
Righto, let’s have a look at what’s on the cards for Agios Ioannis.
Honestly, mate, the next week or so is pretty quiet. We’ve got a long gap of flat, tiny, or messy conditions ahead. From now through to around the 19th of September, it’s mostly small, weak, and chopped-up slop. Not worth paddling out for. The water’s a bit of a shocker too – when we do get the first little bump on the 13th, the ocean is sitting at 81°, which is over three degrees warmer than normal for this time of year. That’s very unusual, and not something you’d expect.
Things start to look a little more interesting from the 20th. On Sunday the 20th, we get a pulse of swell pushing 4ft from the ENE, with a short period of 6 seconds. The combined energy is only moderate (124), and the wind is a cross-shore from the NNW. It’s still got a bit of a chop, but it’s a sign of life.
The standout window comes on Saturday the 26th of September. The morning session is the pick of the whole forecast. We’ve got clean conditions with a cross-offshore breeze from the NW, and a solid 4ft swell from the ENE with a 7-second period. The combined energy is moderate (200). This is the only time where the wind truly cleans it up and the swell has a bit of push. It won’t be perfect – the period is short – but for Agios Ioannis, which is inconsistent and needs a specific NE swell direction to fire, this is your best chance. Keep in mind, it’s a point break, so the swell direction is not quite dead-on the optimum, but it’s close enough to be fun.
Before that, Monday the 21st sees some size – up to 6ft from the ENE – but the cross-shore wind and chop will make it a bit of a battle. That’s getting into the bigger range, but the quality is only marginal. For the crew, it might be more interesting for kite surfing than trying to get a clean paddle wave.
After the 26th, it fades back into small, poor conditions into the end of the month. So, circle that Saturday 26th morning. It’s the only real highlight in a long, quiet run.

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.
