The Lowdown
Alright, grab your board and let’s talk about what’s coming up. To be honest, looking at the next two and a half weeks, it’s a bit of a flat spell for Agios Ioannis. We’ve got a good long stretch of nothing to get excited about, so if you’re itching for a wave, you might want to plan something else for a while.
The first few days are basically a write-off. We’re talking tiny, weak swell—nothing with any push. There’s a bit of clean, glassy stuff early Friday morning, but with a swell that’s barely a ripple and a period of only 4 seconds, it’s just not going to break with any sort of shape. You’d be floating more than surfing. This poor excuse for surf continues right through the weekend and into the start of next week. The wind is mostly light and sometimes cross-onshore, which won’t do the small bumps any favors.
Around the 20th and 21st, things start to look a little more interesting, but it’s still not great. We finally see the swell push up to maybe 2.5ft, with the energy starting to build. But it’s still coming in at a short, weak 6-second period, and the winds are either on it or cross-onshore, which will keep it messy. The water is a warm 80.6°, which is over 5° warmer than normal for this time of year—that’s pretty unusual, feels like bathwater out there.
The one bright spot in this whole forecast is around Monday the 21st in the afternoon. The swell kicks up a notch to 4ft from the ENE, and the energy finally jumps to a moderate level (225). It’s still not huge, but it’s the most size we see. The problem is the wind is blowing straight on from the NE at 9 mph, which will chop it up. It’s a marginal call at best on a point break that’s known to be inconsistent. If you’re an intermediate and you’re desperate, that might be your window, but don’t expect perfection.
After that, it just fades away again. The swell drops right back off to nothing, and the last few days of the month are looking completely flat. Being on a point break, it can be fickle, but a stretch this long with almost no surf is a bit of a bummer. Forecasts can change, so keep an eye on it, but for now, this is looking like a two-week dry spell.
That’s the long and short of it. It’s gonna be a board-repair season, I reckon. Hang tight.
