The Lowdown
G’day, Rusty here. Let’s cut to the chase—this stretch ain’t offering much for the next two weeks. There’s a big gap of poor surf from now through the end of August, with only a quick, clean little window in the middle. If you’re keen, you’ll have to wait for it, and even then, it’s small and weak. One morning might give you a tidy glassy wave, but don’t get your hopes up too high.
First up, Agios Ioannis (Agios-Ioannis). It’s a point break exposed to NE swell, but it’s inconsistent and rarely breaks properly. The water’s at 81°F, which is 4°F warmer than average for this time of year—that’s a real standout, so you won’t need a wetsuit. The first few days are poor: Friday the 21st has a 1ft ENE swell at a short 4-second period, light cross-onshore winds, and weak energy (6). Saturday the 22nd is even smaller—0.7ft, glassy but lifeless. Sunday the 23rd goes dead flat. Monday the 24th is the same—tiny 0.7ft to 2ft waves, though the morning is glassy. Through Tuesday and Wednesday, the swell nudges up to 1ft–3ft, but the period stays under 6 seconds, so it’s crumbly mush. The afternoon of the 26th turns choppy with a SE breeze at 12 mph, so not worth the paddle.
Thursday the 27th is your only real highlight. Morning has a 2ft E swell at 6 seconds, but the wind goes glassy in the afternoon with that same 2ft E swell—clean, smooth, and the energy bumps to 31. That’s your best bet for a few clean, if small, corners. But even then, it’s not a wave you’ll remember.
After that, it fades again. Friday the 28th drops to 1ft–2ft, and the weekend gets messy—Saturday the 29th has tiny 0.3ft–0.7ft waves and a cross-shore chop. Sunday the 30th morning brings a bit more size at 5ft from the NNW, with a 6-second period, but the wind is cross-shore at 16 mph, turning it into a jumbled mess. That one’s got some push (energy 148), but it’s short-period junk—not worth the hassle.
The first week of September is more of the same: small, weak, often flat. Tuesday the 1st is glassy in the morning but just 0.7ft, then the afternoon turns cross-onshore and choppy. Wednesday the 2nd has a 2ft E swell with glassy morning conditions—another brief clean window, but still under 3ft. Thursday the 3rd is clean in the morning with a 1ft ENE, but tiny. Friday the 4th and Saturday the 5th are forgettable—0.7ft to 2ft, short period, and mostly cross-onshore.
So, the honest truth: no standout days in this 16-day window. If you absolutely must paddle out, aim for Thursday the 27th afternoon—that’s your one chance for clean, glassy, small but rideable waves. Otherwise, you might be better off doing something else. Water’s warm, so at least you can enjoy a swim. But if you’re chasing real surf, this isn’t the spot. Watch it though—forecasts change, and a point like this can wake up when you least expect it.
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.

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.
