1931 – Well there is no denying that summer is here in Florida! The highest recorded temperature in Florida was recorded at Monticello in Jefferson County on this date. The humid subtropical climate of the small town reached a peak of 109 °F / 43 °C. Warm weather is generally accepted by most Floridians as par for the course, but extremely cold temperatures are much less frequent. On February 18, 1899, not far from Monticello in Tallahassee, a record low of -2° F / -19 °C was reached.
