The Lowdown
Alright, folks, Rusty here. Let’s take a look at Agios Ioannis over the next couple of weeks. I’ll be straight with you – this stretch is looking pretty flat and quiet. There’s really not a single standout session in the whole 16-day run. The first few days are a write-off, and the pattern doesn’t really change much.
We kick off on Tuesday the 25th with a tiny 2 ft east swell, period a short 5 seconds, and a cross-on SE wind at 12 mph. The water is a warm 82°, which is much warmer than normal for this time of year. The combined energy is weak at 14. The surf is poor and choppy. Not worth paddling out.
Wednesday the 26th and Thursday the 27th are even smaller, with swell dropping to 0.7 ft and 1 ft. There’s a brief moment of glassy conditions on Thursday morning, but with only 0.7 ft on offer, it’s a total non-event. The energy is negligible.
Friday the 28th through to the end of August sees a tiny uptick – on Friday afternoon we get 2 ft from the ENE at 5 seconds, with 29 energy, but it’s still cross-on and choppy. Saturday and Sunday are similar, or flat. Sunday the 30th is dead calm with zero swell.
The first week of September doesn’t bring any hope. From Monday the 31st through to Wednesday the 9th, we’re looking at swell heights mostly between 0.3 ft and 2 ft, with no decent period or clean wind alignment. The biggest energy reading we get is 51 on the 9th of September, with 3 ft from the ENE at 6 seconds, but it’s cross-shore and cloudy. Still poor.
The bottom line is: Agios Ioannis is inconsistent at the best of times, and this forecast is a blank run. There’s no surf worth chasing. If you’re desperate for a paddle, maybe check the glassy mornings on the 27th or the 4th of September, but you’ll be sitting on a lake. The forecasts can change, but right now, leave the boards in the car.
Rusty.

A general guide to surfing at Agios Ioannis can be found by selecting the local surf guide option on the grey menu.

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.
