The hottest temperature ever officially recorded in Louisville is 107 degrees, which has occurred on three different dates. The first time it was 107 degrees in Louisville was on July 24, 1901.

I've been to the Louisville area a number of times, but always in the spring to attend the horse racing at Churchill Downs and nearby Keeneland, which is in Lexington. Sometimes even in the spring it can get pretty hot in Louisville. They have certainly had 90 degree weather days on the first Saturday in May in Louisville when the Kentucky Derby is run.

As a bit of weather trivia some might find hard to believe, the record hottest temperature in Louisville of 107 degrees is exactly seven degrees hotter than the all-time hottest temperature ever recorded in Miami, Florida. Louisville is over 1,000 miles north of Miami.

The all-time record hottest temperature ever recorded in the state of Kentucky is 114 degrees, which occurred on July 28, 1930, in Greensburg. Located along the Green River, the city of Greensburg is about 80 miles south of Louisville, not too far from Mammoth Cave National Park, which is a cool place to visit.

The difference between the all-time hottest temperature ever recorded in Louisville (107) and the all-time hottest temperature ever recorded in the state of Kentucky (114) is seven degrees. Not a huge difference, but still a statistically significant difference.

I would not say that below zero temperature days are common in Louisville, but they certainly do occur. Since 1872, there have been nine days when the temperature dropped to -15 degrees or colder in the city. Louisville averages 87 days a year when the temperature drops below freezing.

The city of Shelbyville is located only about 35 miles east of Louisville, and the state record for Kentucky was set on the same date Louisville set its coldest temperature record.

The difference between the all-time coldest temperature ever recorded in Louisville (-22) and the all-time coldest temperature ever recorded in the state of Kentucky (-37) is 15 degrees. A pretty large statistical difference, which is pretty surprising since Shelbyville and Louisville are not very far apart.
