September 10 used to be a very hot day in the US, but over the last 120 years September 10 temperatures have plummeted.
On September 10, 1931 most of the Eastern US was over 90 degrees. Minnesota reached 107 degrees, and 100 degree temperatures were recorded in New York State and Wisconsin. New York City was 96 degrees – 25 degrees warmer than today.
A hurricane also hit Belize that day, killing more than 5% of the population. h/t gator
