The Lowdown
Alright, crew, Rusty here. Let’s cut to the chase: the next two weeks are looking flat and pretty uninspiring. There’s no big swell coming, so if you’re hoping for some real waves, you might want to look elsewhere. On the bright side, the water is much warmer than normal for this time of year at 81°F, so a swim is always on the table.
The first tiny glimmer of hope arrives on Monday the 10th. Agios Ioannis (Thassos) will see a meager 3ft of east swell with a 6-second period, and the energy is weak at 59. The wind will be dead calm and glassy, which is nice, but with waves that tiny and powerless, it’s going to be a frustrating session. It’s a spot that’s inconsistent, so we’re used to this sort of thing.
Wednesday the 13th sees a slight bump. The afternoon brings a 3ft east swell, again with a 6-second period. The energy is moderate at 122. The wind will be light and glassy again, so it will be clean, just lacking any real punch.
If you want the best chance at something with a bit of push, circle Friday the 14th. The morning has the most size of the whole window, with a 6ft east-northeast swell and a 7-second period. The energy is strong at 497, which is a real injection of power. But, a light cross-onshore wind will put a bit of bump on it. It’s the biggest surf we’ll see and will offer the most power, but it’s not going to be perfect. Saturday morning will still have size at 6ft, but the energy drops to 439 and the wind gets more onshore, making it choppier.
After the weekend, it’s all over. From Sunday the 16th, the swell drops right off. We are looking at waves under 3ft, with periods of 4-6 seconds, and weak energy. It’s a long stretch of flatness that carries through to the 23rd. A few glassy mornings will tease us, but with no swell running, it’s no good for surfing.
So, the takeaway is that this is a blank run. The one standout is Friday the 14th, but it’s not for beginners. At over 5ft, it’s definitely pushing into expert territory, and the short period means it could be a bit shifty. For the experienced locals, that’s your one chance to get a few turns in over the next fortnight. Don’t hold your breath for anything else.
Rusty, out.
