The Lowdown

Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty bleak for a proper surf. We’ve got a long stretch of tiny, weak swell and not much push behind it. If you’re just jonesing for a paddle, there’s a chance to get wet, but you’ll be hunting for anything rideable. The real story is the water, which is sitting at a very warm 81.7° and running about 6.3° warmer than normal for this time of year. That’s a big deal—it’s seriously unusual and means you can get away with just boardshorts.

Now, looking at the forecast for Agios Ioannis, we start off with a bit of energy on Tuesday the 8th, but it’s messy. We’ve got a 3.3ft swell from the ENE with a short, weak 6-second period. The wind is cross-onshore from the east at 9 mph and it’s choppy. The swell energy is weak at 102, and the call is poor. Don’t get too excited. The afternoon bumps up slightly to 3.9ft, but it’s still the same story—short period and that choppy onshore wind, so it's pretty junky.

Wednesday the 9th is still small and onshore, with 3.3ft in the morning but a weak 116 energy reading. It’s marginal at best. The afternoon drops off to 3.0ft and the energy falls off a cliff to 68. Thursday the 10th, the swell just dies. We’re looking at a measly 1.0ft in the morning and 2.3ft by the afternoon, with energy levels down in the single digits and teens. It’s not happening.

Friday the 11th has a bit of a novelty to it. The morning shows complete glass—zero wind!—but there’s only 1.3ft of swell on a 4-second period. It might be pretty, but there’s nothing to ride. The afternoon’s a similar story, 2.0ft and a light breeze.

From Saturday the 12th through the following week, it pretty much flatlines. There are days with glassy conditions and even some offshore winds, but with swell heights of 0.7ft or less and energy readings of 1 or 2, you’re not surfing. The middle of next week—Monday the 15th through Wednesday the 17th—has some clean conditions and offshore winds, but there’s zero swell. It’s a flat spell, pure and simple. This is a real dead period for the region. It’s not unusual for this stretch to go blank, but that doesn’t make it any easier to take.

The one glimmer on the horizon is the 21st. Monday afternoon shows an onshore wind but a pulse of 3.0ft from the NNW. It’s still small, and with a 5-second period, it’s not going to have any power. It’s marginal. After that, it drops right back off again. We’re also seeing some fresh to strong winds on the 20th, which will just add to the messy conditions.

So, in a nutshell, there is no standout session in this forecast. You’re looking at a two-week stretch of close-outs and flat spells. If you’re a beginner, the small stuff is safe enough, but it’s not going to be fun. For everyone else, it might be worth finding another hobby for a few days. This is one of those times where the ocean is just taking a break. Remember, it won't stay poor forever, and forecasts can change, but as it stands right now, you're not missing anything.

Stay patient.

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.
