DENVER — You shouldn’t think that big snowstorms aren’t possible this time of the year despite 80-degree temperatures of this year.

Sept. 27 marks the anniversary of a very large snowstorm that hit Denver in 1936.

According to the National Weather Service, “The heaviest snowfall ever recorded in September and the heaviest snowfall ever recorded so early in the season dumped a total of 16.5-inches of snow on downtown Denver and 21.3-inches at Denver Municipal Airport. The 15.0-inches of snow measured from 6:00 PM on the 27th to 6:00 PM on the 28th is the greatest 24-hour snowfall ever recorded in September.”

September 1936 was not the only snowy one on record. In 1971, there was a snowier stretch of days that totaled 17.2 inches at Stapleton International Airport.

Granted, the September average snowfall amount is only 1 inch; that doesn’t imply we can’t see big storms. That is unless you look at recent history.

With this year included, the past 16 Septembers have not totaled a single inch. The last time the city had more than 6 inches in September was 1985.

The remainder of this September will remain unseasonably warm, and therefore snow-free.

October, historically, averages nearly 5 inches of snow. The largest October snows were in 2009 with 17.2 inches, 1923 with 17.9 inches, 1997 with 22.1 inches, 1906 with 22.7 inches and 1969 with 31.2 inches. That was the snowiest October in the city’s record.
