The Lowdown
Alright folks, ol’ Rusty here with the full rundown for the region. Let’s be straight with you from the start, it’s a tough stretch of days ahead. We’ve got a long dry spell before anything worth paddling out for shows up.
The first good sign of life doesn't hit until the morning of Thursday, 23 July. Agios Ioannis is a point break, exposed to the NE swell, but it’s inconsistent here. The morning of the 23rd we’ll see a modest pulse of ENE swell around 4ft with a short period of 6 seconds. The wind is light cross-shore from the N at 6 mph, so the surface will be tidy enough. The combined energy is a moderate 101, which is about the only time we see any real oomph. The water is a notable 82°F, which is a massive 6°F above normal for this time of year – way warmer than usual, so you won’t need a thick suit.
Through the afternoon of the 23rd, that swell drops to 3ft with the period still short, and the cross-onshore ESE breeze at 9 mph will chop things up a bit. The next morning, Friday the 24th, is small again at 2ft and messy. By Friday afternoon, forget it – a near gale from the NNW at 34 mph makes it a write-off.
The weekend offers nothing. Saturday the 26th and Sunday the 27th are flat with zero energy. The next time we see any swell is the morning of Tuesday, 28 July. A new pulse from the NNW at 5ft, but it’s short period at 5 seconds and the wind is a fresh cross-shore from the NNW at 19 mph, creating lumpy, choppy conditions. The wave energy is only 98, so it’s weak and messy. Not a standout.
The following days are a mix of tiny, weak waves. The best of a bad bunch looks like the morning of Sunday, 2 August. We’ve got a waist-high 3ft swell from the ENE with a 6-second period, and the wind goes glassy – light NNE at 3 mph. The combined energy is 50, so it’s weak, but those glassy conditions will make it clean. The wave comment says “surfable waves but very ordinary conditions,” which is about as good as it gets here. Because the break is inconsistent, you’ll be waiting for sets, but if you just want a splash, that’s your window.
Honestly, none of this is a true standout. The only real highlight is that glassy session on Sunday the 2nd, but don’t expect any power. The rest of the forecast is a flat spell or blown out junk. If you’re desperate, keep an eye on that morning.
Stay patient, gang. Rusty out.
