Denver Climatological Preview - October 2022 |

Preview of Thornton's October Weather - Fall is Here
The month actually has our second highest amount of sunshine with 72 percent with September having the most with 74 percent. Interestingly enough, the month following, November, is one of the lowest sunshine months with only 64 percent. Typically October brings our first real taste of winter with the first freeze on average coming on the 7th of the month and the first snow on the 15th of the month. Overall October averages a temperature of 50.9 degrees. This makes it the fifth warmest month of the year behind July, August, June and May respectively. Average high and low temperatures in October steadily drop throughout the month. On the first we average 72 degree highs but by the 31st that drops to 59 degrees. October also sees our average low temperatures start to reach below freezing as well. At the start of the month we will average 42 degrees as the low temperature but by the end of the month the mercury dips to 31 degrees. This truly begins the sign that winter is approaching. Temperatures can run from one extreme to the next during October. The record high temperature is 90 degrees which was set on October 1, 1892. By contrast, the coldest temperature was 2 degrees below zero set on October 29th, 1917. Those temperature swings can occur in a very short period of time as well. On October 2, 1969 Denver enjoyed a balmy high temperature of 85 degrees. Over the next two days though on the 3rd and 4th, 15 inches of snow fell in the area. Another example of those changes happened in 1991 when on the 16th we reached 89 degrees then had record low temperatures of 7 degrees on the 30th and 10 degrees on the 31st. October on average is our 5th driest month, averaging 0.97 inches of precipitation (rain and snow melt combined) with 4.1 inches of snow on average during the month. Precipitation overall can range from a trace to a record of 4.17 inches of precipitation in 1969. 1934 was the driest October on record with only a trace recorded. In terms of snow, there have been some years when no snow or only a trace of snow was recorded – in 32 out of the last 133 years that was the case. Record setting precipitation was the highlight of October 2007. In the 24 hour period between October 13 and 14, 2.65 inches of precipitation was recorded at DIA. This broke the previous 24 hour record of 2.58 inches set on the 12th and 13th of the month in 1892. The previous daily record of 2.11 inches in 1892 was also broken with 2.48 inches of precipitation on the 13th. What is probably one of Denver’s most famous snowstorms occurred in October and was seen live on national television. On Monday, October 15th, 1984 the Denver Broncos faced off against the Green Bay Packers at Mile High Stadium in what came to be known as the “Bronco Blizzard.” The storm gradually intensified during the game and by the end of the game the field was covered with four inches of snow. By the time the storm was over, over a foot of snow had fallen in most of the metro area. The weather proved to be the deciding factor in the game as the Broncos recovered two back to back Packer fumbles and returned them for touchdowns, winning the game 17-14. Ski areas rejoiced in their “white gold” and saw a surge in reservations from out of state as the nation watched this tremendous storm unfold on television. October 1997 saw tremendous snowfall and ended up being the 3rd snowiest October in Denver history. From October 24th to 25th 19.1 inches had fallen during a 24 hour period, setting a new October record. By the time the storm ended, 21.9 inches of snow had fallen at Stapleton International Airport over the two day period. October Extremes October: Denver's Top 5 Warmest (mean temperatures): October: Denver's Wettest October: Denver's Snowiest Outlook for October 2022 The latest long range outlooks from the Climate Prediction Center point to good chances for warmer than normal temperatures but also wetter than normal conditions. The agency gives most of the state a 40% to 50% chance of above normal temperatures. In terms of precipitation, precipitation along the Front Range is given a 33% to 40% probability of above normal levels.
