Typically November is a quiet weather month with plenty of nice, fall days but it can also turn wet with plenty of snow and moisture. Just like Forest Gump's proverbial box of chocolates, you never quite know what you are going to get.
Looking into the weather history books, we see that November is actually Denver's second snowiest month, second only to March (April is third). Historically we average 10.7 inches of snow during the month.
In 1994, November was the snowiest month of that year with 16.9 inches - over 12 inches of which fell within a 12 hour period on the 13th and 14th. In 1991 we saw 29.6 inches of snow (the 2nd snowiest November) and the following year in 1992 we had 20.1 inches of snow (the 8th snowiest November). Those examples though pale in comparison to the snowiest November on record which was in 1946 when a whopping 42.6 inches of snow fell!
It isn't always that snowy though. November 2002 was at the time the 16th month in a row with below normal precipitation and the calendar year of 2002 marked the driest in Denver weather history. This pattern of below normal precipitation continued for 19 months through February 2003. Since 1882, one year (1949) recorded no snow, six more recorded only a trace of snow and four had less than one inch of snow.
Historically, temperatures can also vary widely during the month. The overall average November temperature is 37.5 degrees with an average high for the month of 51.5 degrees and an average low of 23.5. In recent history, November 1999 finished as the second warmest November with an average temperature of 47.1 degrees. But, a year later November 2000 finished as the second coldest November in Denver weather history with an average temperature of 28.9 degrees. The coldest November on record? In 1880 Denver had an icy 22.0 degree average. The warmest occurred in 1949 with an average temperature of 50.9 degrees.
One little known fact... November is the area's least sunny month, tying with May with only 64 percent sunshine. September is the sunniest month with sunshine 74 percent of the time.
