The Lowdown
Alright, Rusty again. Let's run through this one for the imperial crew. The outlook for Agios Ioannis is pretty grim for a while. We're looking at a long stretch from Wednesday the 9th right through to the 22nd of September where there's just no real swell to speak of. Flat, clean, but flat.
The one thing that finally shows up is on Wednesday the 23rd of September, and it’s not an easy call. The morning brings a 6ft swell from ENE with about 307 combined swell energy (moderate to strong), but the wind is coming out of the ESE at 15 mph, which ruins the surface. That afternoon, the swell drops to 4ft from ENE, energy at 144 (still moderate), and the wind stays on you from the SE at 15 mph. The period is only 7 seconds, so this is all windswell, not that smooth groundswell you can sink your rails into. The point setup here can handle it, but with the onshore flow, it's going to be choppy and bumpy. More of a kite surfing afternoon than a clean surfing one.
The water temp on the 9th is pushing 82°, a solid 6° above normal for this time of year, so at least it's warm while you're sitting there waiting for waves that aren't coming.
Bottom line: the 23rd is your only real chance, and it’s not a pretty one. You might score a few lumpy ones if you're desperate, but it’s not a standout day by any stretch.
Rusty out.
