October 1963 - remarkably warm & dry, North America

[Optimus Prime]

October 1963 was and still is an historically warm month for North America with only the extreme west coast and the extreme western portion of Alaska avoiding it. This heavily contributed to the warm run of October's of the 1960's. There were also a couple of notable hurricanes that didn't quite reach the shores of the USA (but hurricane Flora did impact Cuba) .

Chicago recorded an air temperature 9 degrees Celsius above normal coined by the media at the time as "The warm October that refused to quit".

The air temperature anomaly map showing temperatures widely 3 - 7 degrees Celsius higher than normal. 

October 1963 currently ranks 2nd warmest, after 2021. The overall anomaly being ~1.9 C above normal

The October's of 1962, 1965 and 1968 were also on the mild side. 1969 was a notable cold one across the bulk of the United States, but remarkably warm across the whole of Alaska.

I appreciate a historic post about weather outside the UK. More of it I say! October 1963 was a pretty mild one over here too.
