Decorah typically has a freeze by Oct. 8, according to Decorah Meteorologist Richard Bernatz.

During the 117 years complete temperature data has been collected, Decorah had a temperature of 32 degrees or lower by the 8th of October in 97 of those years, he said.

"If we go another seven days without frost, that would represent only the seventh time we've made it that late without a frost," Bernatz said.

The latest date for an "official" temperature of 32 or less for Decorah is Oct. 30, which occurred the fall of 1973.
