After a week of incredibly nice weather, and beautiful sky, Shanghai returned to its gray, hot, and humid nature of summers.

Currently, the temperature of Shanaghai is 35°C, and humidity is 53%. I often pay more attention to temperature (well, this time, the visit to US enforced my attention to this metrics), but generally ignore humidity.

What does 53% means? I need to find out later. According to Wikipedia article on Humidity, “Shanghai and Hong Kong in China also have a extreme humid period in their summer months”. It is talking about weather like today. The 6km SW wind does not help at all.

Visiting Shanghai these days? Bad choice.

P.S. I am still keeping the sleep early and raise early theme after getting back to the States. The jet lag on the way back always helped to keep me an early raiser for a week or two before I return to my normal status. The key learning is, the only way to raise early is to go to bed early enough that you cannot fall asleep easily (an indicator that you slept early enough).
