While the winter of 2018-19 was certainly a snowy one for Denver and the state of Colorado, the just-completed 2010-2019 decade tells a considerably different story.

A total of 451.3 inches of snow fell in Denver between 2010 and 2019, making it the second-lowest decadal snowfall on record, and continuing a recent 20-year downward trend of Denver snowfall. The 2010-2019 451.3-inch snow total is only narrowly ahead of the 2000-09 snow total of 444.3 inches.

Including the 2010-19 data, Denver has averaged 573.8 inches of snow per decade since 1890. That puts each of the last two decades well behind the long-term average, and another strong indicator of a significant recent slump in Denver-area snowfall.

These statistics are based on snowfall data from the old Stapleton Airport site from 1950 through 2019, and various downtown Denver locations between 1890 and 1950. While Denver’s official snowfall data is currently collected at Denver International Airport, snowfall observations only began there in the 1990s, making long-term comparisons there more difficult.

Three winters last decade were particularly snow-free in Denver. The winters of 2010-11, 2016-17 and 2017-18 winters all ranked among Denver’s five least-snowy winters ever recorded.
