Okay, I know this is picky but the average high temp for July in NYC, according to NY.com, is only 85.

Most the time in HK I am waking up with temps around that high. Further, the average NYC low is 68. That means that high temp probably isn't reached until mid-afternoon and that most of the day is spent in the 70s whereas in HK it is spent in the 80s. Today it was 91 on my balcony at 630 pm. I have seen my thermometer hit 100 in the shade and 118 in the sun.
Plus, as we previously agreed, it is a lot more humid here and as I pointed out earlier the air pollution here is worse than NYC. The dogs are in for a rude awakening.
But you're right in that both places are a lousy place to have a fur coat on in the summer.
