By contrast, interesting to think there are places north of 60N in Europe that have never gone below 0F.. funny how different climates work.

For NYC, and other cities, y'all are forgetting the Urban Heat Island Effect.

I've never recorded a temperature lower than 0F at 53 degrees north..

yeah, the Gulf Stream is a magical thing. Or a terrible thing for me.

I don't think the urban heat effect in Tallahassee is nearly as strong as it is in NYC. IIRC, cities up and down the eastern seaboard, including Tallahassee, had nights that were nearly as cold as NYC last December.

These record low temperatures are unlikely, but not impossible.

The decrease in sub 0 temperatures in NYC is striking.

Seriously though, NYC has grown so much since the 1800's, no wonder the frequency of sub-zero temperatures has decreased in NYC. Similar in London, a temperature of -21C was reported in London in the 1700's but more or less impossible today due to the huge Urban Heat Island.

Meh. I thought all of Europe was colder in the 1700s.

Going back to NYC, the frequent below zero temps continued till the 1940s. NYC was similar in population to today by the 1940s, though the outer suburbs hadn't been developed yet, but those are at least 20 miles from the Central Park Weather Station, so they shouldn't add much to the heat island. Manhattan and some nearby areas were mostly built up by the end of the 1800s. I'd imagine the fact it being in Central Park would buffer the effects of the heat island a bit.

On a related note, where the hell do you live anyway? Trust you not to put your location in your profile
