Weather Talk: 1st freezing temperature occurred late this yearA week ago, on Oct. 16, the low temperature at Hector International Airport dropped to 29 degrees. That was the first time this season that the air temperature had dropped to 32 degrees or lower in Fargo-Moorhead.
Since records began in 1881, there have been only four other years in which the first frost of autumn occurred on a later date. Those years include the latest first frost on record, which was recorded on Oct. 24, 1994, and the other three years were on Oct. 22, 2007, Oct. 20, 1911, and Oct. 19, 1938.
Although our current average first frost is on Sept. 30, including this year, the first freezing temperature of fall has occurred in October only 40 times – meaning slightly less than one year in three has the growing season extend into the month of October.
The average last frost of spring is on May 8, only 197 days away and counting.
