With all the talk about hot temperatures and arctic sea ice melting, just to cool things off, the current temperature at the South Pole is -68 and wind chill -100.
I was just checking buoy reports in our area. Sure enough, water temperatures in our area are close to 80, yet Atlantic City is 68.7 as of this afternoon. Ocean City Md. to Cape May N.J. appear to be about 75.

This is about the best I can find for location of the weather station at LaGuardia, for anyone interested.

I was a kid way before 1994 and growing up the summers were cooler than now but also dryer. I think there is much more storm activity now than then. I find it more interesting now.
Virginia has quite a variation from north to south. Areas of northern Virginia, such as Dulles airport, have always been fairly close to NYC temperatures, at least in the colder months. The summer months down there are hotter.
Lets not forget the heat island affect, especially when it comes to night time temperatures. NYC has had a skyscraper boom in the past 10-15 years. That concrete simply does not allow the heat to escape at night.
So in 50 years the average dew point temperature at Islip has gone from 64 to about 66-67. It does look like we have been in a high trend for the past 9 years. Before 2010 it doesn't look like a big change.
