As Denver flips the calendar to November, residents are starting to wonder—where’s the snow? The Mile High City, famous for its unpredictable weather and sudden winter swings, has yet to record its first measurable snowfall of the season. While it’s not unprecedented, this year’s snow delay is running later than usual and has locals eyeing the sky with growing impatience.
A Late Start to a Snowy Season
On average, Denver typically sees its first measurable snowfall (at least 0.1 inches) around October 18th, according to National Weather Service records dating back to 1882. But here we are, nearly a month past that average date, and the city’s lawns and rooftops remain bare.
The last time Denver’s first snow came this late was in 2021, when flakes didn’t fall until December 10th—the latest start to winter in recorded history. That season ultimately ended with a respectable 49.4 inches of total snow, proving that a slow start doesn’t always mean a weak finish.
Other notably late first snows include:
- November 21, 1934 (1.0 inch)
- November 19, 1931 (1.0 inch)
- November 17, 2016 (1.7 inches)
- November 15, 2010 (1.5 inches)
If the trend continues, 2025 could join that late-start list.
Early Freezes, Late Snowfalls
Denver’s seasonal clock can be quirky. While the city often experiences its first freeze by October 7th on average, the first snow doesn’t always arrive right after. This year, Denver’s first freeze occurred on October 18th, close to the recent 10-year norm.
For perspective, the earliest recorded freeze in Denver’s history came shockingly early—September 8, 1962, a date shared by 2020, which also brought a rare early snow the same day (1.0 inch). Meanwhile, the latest first freeze didn’t happen until November 15, 1944, a delay that mirrors the kind of mild autumn Denver has seen so far this year.
From Deep Winter to Spring Thaw
Denver’s climate is famous for its wild swings, and the statistics bear it out. The city’s last freeze typically occurs around May 5th, though history shows wild variation. The latest on record was June 8, 2007, while the earliest last freeze came on April 5, 1977 and 1981.
That means Denver’s growing season can range from about 150 days to well over 200—depending on the year’s mood.
What This Means for Winter Ahead
While some might worry a late first snow signals a mild winter, Denver’s weather history doesn’t necessarily agree. Several of the city’s snowiest winters have followed late starts. For instance, the winter of 1987–88 saw its first snow on November 15, yet finished with a hefty 62.3 inches of total accumulation.
Seasonal forecasts suggest that El Niño conditions lingering in the Pacific could steer more moisture toward Colorado later this winter. That might translate to fewer early storms but potentially more significant snow events in December and January.
The Bottom Line
Denver’s weather is nothing if not dramatic. From freezes as early as September to snowstorms as late as May, the Mile High City lives up to its reputation for meteorological mood swings. So, while it might feel strange to be snow-free in November, history shows the flakes will come—often when we least expect them.
And when they do, they’ll likely remind us why Denver’s winters are as unpredictable as they are unforgettable.
