October 2025 weather recap: Much warmer, much drier than normal

Thornton, Colorado’s October 2025 Temperature Summary. (ThorntonWeather.com)

Thornton’s first full month of fall for the year yielded lots of dry mild days. While that made for some pleasant conditions, it was exceedingly warm and dry.

The month started out with mercury readings in the 80s for the first four days then we cooled down. Three days with readings closer to normal followed as did some nice rain.

We then strung together more than two weeks of largely above average temperatures and very minimal precipitation. The final five days did cool down some and bring a little bit more rain.

Thornton’s overall average temperature for the month came in at 52.9 degrees. This was well above our running 19-year average for the month of 50.1 degrees. Temperatures ranged from a high of 87.8 degrees on the 3rd down to a low of 22.6 degrees on the morning of the 29th.

Out at DIA where Denver’s official measurements are taken, it was a bit warmer. The Mile High City saw an average temperature for the month of 53.5 degrees, well above their long term average for October of 51.1 degrees.

In terms of precipitation, it was lacking a good bit. Thornton recorded 0.56 inches in its rain bucket, the vast majority of it (0.50”) coming on the 5th and 6th. This was much less than our running October average of 0.94 inches.

At the airport, Denver was even drier. They saw a mere 0.14 inches in the bucket, far less than the Mile High City’s October average of 0.99 inches.

No snow was recorded in Thornton or in Denver. This already puts us at a deficit to start the snow season. On average, Thornton receives 3.6 inches in October.

Denver sets two high temperature records on November 2nd

Record High Temperature

It was ridiculously warm today, certainly something we would expect to see in early October, not November. The mercury readings resulted in Denver setting two records.

The high temperature, as measured at Denver International Airport, reached 83 degrees. This sets a new high temperature record for the date, besting the old record of 78 degrees set in 1931.

Also, the 83 degree reading sets a record high temperature for the month of November. The previous warmest November reading was 81 degrees on November 27, 2017.

Here in Thornton, we also topped out at 83 degrees. This was the warmest November 2nd and the warmest November reading overall in the 19 years this station has been in operation.

80 degree readings in November are a rarity. In fact, today’s is only the fifth in Denver since record keeping began in 1872.

83 – 11/02/2025
80 – 11/06/2021
81 – 11/27/2017
80 – 11/16/2016

This Week in Denver Weather History

Snow and wind are recurring themes in our look back at this week in Denver weather history. Among the more notable events are a four-day snowstorm in 1946 that dumped an astounding 31 inches of snow on the city.

From the National Weather Service:

1-2

In 1892…snowfall totaled 5.0 inches in downtown Denver. This was the only snow of the month.

In 1956…heavy snowfall totaled 7.0 inches at Stapleton Airport. The storm was accompanied by much blowing and drifting snow. North winds gusted to 47 mph.

In 1991…the storm system which hit the Front Range at the end of October finished the job during the start of November. Six inches of new snow were recorded at both Rollinsville and Morrison…while 2.9 inches of snow fell at Stapleton International Airport where northeast winds gusted to 17 mph. The temperature climbed to a high of only 19 degrees on the 2nd…setting a record low maximum for the date.

In 1995…a winter storm dropped 5 to 8 inches of snow in the Front Range foothills. The exception was at Golden Gate Canyon where a foot of new snow was measured. Icy roads…fog…and blowing snow along I-70 in the foothills west of Denver caused dozens of accidents. One man was killed when he lost control of his vehicle and was ejected when his truck hit a median and rolled over. At least 20 other accidents involved minor injuries. Only 1.0 inch of snow fell at the site of the former Stapleton International Airport where some freezing rain also fell.

2

In 1939…a trace of snow fell over downtown Denver. This snow…along with a trace of snow on the 9th…was the only snow of the month…ranking it…along with other months…the second least snowiest November on record.

In 1967…post-cold frontal heavy snowfall totaled 6.2 inches at Stapleton International Airport where north winds gusted to 29 mph…briefly reducing the visibility to 1/8 mile.

In 1992…the first major snowfall of the season dumped 4.6 inches of snow at Stapleton International Airport where north winds gusted to 26 mph. Heavier amounts of snow fell in and near the foothills with 8 inches at Conifer… Empire…and Bailey…6 inches at Rollinsville and Golden Gate Canyon…and 4 inches at Morrison and Wheat Ridge.

In 2011…a storm system brought another around of moderate to heavy snow to the region. Areas in and near the Front Range foothills and Palmer Divide were hit the hardest. Gusty winds also produced blizzard conditions at times along the Palmer Divide. In addition…the snow and blowing snow forced several school closures in Douglas and Weld counties. Snow drifts…from 1 to 3 feet deep were reported in the northern portion of Douglas and Elbert counties. Storm totals included: 14 inches…4 miles south of Boulder and 12.5 miles northwest of Golden…13 inches… 5 miles east-southeast of Aspen Springs; 12 inches near Allenspark and Parker; 11 inches…6 miles southwest of Castle Rock…Genesee…9 miles north-northeast of Elizabeth…10 inches…10 miles south-southeast of Buckley AFB.

In 1990…a winter storm dumped 3 to 8 inches of heavy wet snow across metro Denver. In the foothills snow amounts ranged from 4 to 10 inches. Slushy snow and ice-covered roads snarled traffic. The snow…ice…and poor visibilities were blamed for numerous traffic accidents. Low clouds… Fog…and snow delayed air traffic at Stapleton International Airport for at least 90 minutes on the afternoon of the 2nd. Snowfall totaled 5.4 inches at Stapleton International Airport where north winds gusted to 21 mph.

In 2018…a powerful and moist Pacific jet stream brought a period of moderate to heavy snow and blowing snow to the mountains west of Denver with up to a foot of snow. A strong gust front generated from dissipating showers near the foothills of southeast Larimer and eastern Boulder counties pushed across the I-25 corridor and adjacent plains. As the gust front swept across Denver International Airport…a peak wind gust to 58 mph was observed from the west-northwest.

2-5

In 1946…a major snow storm dumped 30.4 inches of heavy snowfall downtown and 31.0 inches at Stapleton Airport. The winter storm closed schools and disrupted all forms of transportation in the city. The greatest depth of snow on the ground was 28 inches at the airport. The duration of the snowfall…from 4:22 am on the 2nd to 3:08 am on the 5th… A total of 70 hours and 46 minutes…is the second longest period of continuous precipitation on record and the second heaviest snowfall of record at the time in Denver. The 17.7 inches of snowfall on the 2nd and 3rd was the greatest 24- hour snowfall ever recorded during the month of November. Buses and street cars had a difficult time…and many cars were abandoned along roadsides and streets for several days. Secondary roads in rural areas were blocked for 2 to 3 weeks. Several buildings in the city collapsed or were damaged from the weight of the heavy snow. Football games were canceled. Livestock losses were high over eastern Colorado.

Hazardous conditions developed in Denver along an elevated portion of 6th Avenue during the early morning commute. The crash involved approximately 100 vehicles. There were no serious injuries… although one driver had to be extricated from a vehicle. The accidents occurred between Kalamath Street and Federal Boulevard. Numerous tow trucks took damaged or inoperable vehicles to a parking lot outside Empower Field at Mile High. The icy road conditions made it impossible for drivers to prevent from slamming into each other. A major cleanup had to take place before 6th was reopened later in the morning. The closure lasted approximately 5 hours. Several crashes occurred along Interstates 25 and 70…and included a multi-vehicle accident on the onramp from US 36 to I-25.

November 2025 preview: The transition to winter begins

November

The weather during the month of November in Denver metro area can offer just about anything.  While it is normally a quiet month, it can be prone to extremes.

November has historically been one of Denver’s snowiest months and major snowstorms are not entirely uncommon.  However conditions can also be quite dry.

Temperatures during the month continue to cool as we get closer to winter and by the end of the month the low temperatures routinely dip to 20 degrees or below.  At times it can in fact bring conditions more like what we see in January.

Get all the details on November’s weather and what we can expect in our complete preview here.

Time to “fall back” as Daylight Saving Time ends Sunday, November 2

Daylight Saving Time
The United States returns to Standard Time at 2:00am Sunday as Daylight Saving Time comes to an end.

The biannual ritual of changing our clocks to adjust for Daylight Saving Time occurs this weekend, providing yet another signal of the changing of seasons.  The United States will ‘fall back’ one hour at 2:00am Sunday morning as we return to Standard Time.

The ritual of changing our clocks twice a year can be met with some resistance as some people struggle to adjust their body’s internal clock.  Others actually like the return to standard time as they get to enjoy an extra hour of sleep.

The time change definitely has big effects on the dawning of daylight and how early it gets dark in the evening.

Sunrise on Saturday occurs at 7:29am but on Sunday it will be at 6:30am. Similarly, sunset will occur at 5:57pm on Saturday but on Sunday the sun will disappear over the horizon at 4:56pm.

For many this means that when they get home from work it will now be dark and outdoor activities will be significantly curtailed as a result.

Arizona and Hawaii are the only states that do not observe Daylight Saving Time and remain on Standard Time year round.  The U.S. territories of Puerto Rico, American Samoa, Guam, Northern Mariana Islands, and the United States Virgin Islands also do not observe the event.

It won’t be all that long though before Daylight Saving Time returns.  On March 8, 2026 we will ‘spring forward.’

Daylight Saving Time Schedule

The mandated beginning and end of Daylight Saving Time has changed in the United States over the years.

The most recent schedule was set by the Energy Policy Act of 2005 and took effect in 2007.  We now ‘spring forward’ to begin Daylight Saving Time on the second Sunday in March and ‘fall back’ with the return to Standard Time on the first Sunday in November.

Daylight Savings Time Dates

Year DST Begins 2 a.m.
(Second Sunday in March)		 DST Ends 2 a.m.
(First Sunday in November)
2025 9 March 2025 2 November 2025

October 26 to November 1: This Week in Denver Weather History

Leave a comment

This Week in Denver Weather HistoryWind can be one of the most frustrating weather conditions to experience and our look back at this week in Denver weather history shows the period has seen more than its fair share. Also notable are many significant snow events that have occurred in the Mile High City over the seven day period.

From the National Weather Service:

25-27

In 2021…the minimum temperature at Denver International Airport dropped into the single digits for three consecutive mornings: 8 degrees…4 degrees and 8 degrees respectively.

26

In 2010…very strong winds during the day knocked down power lines in parts of Boulder. The downed electrical lines sparked a small brush fire near Columbine Elementary School. Strong wind gusts also damaged the tennis bubble at the Millennium Harvest House. In Northglenn, a tree was knocked down and caused minor damage to a mini-van parked nearby. Peak wind gusts included: 70 mph at Berthoud…67 mph at Rocky Mountain Metropolitan Airport in Broomfield… 63 mph at the Rocky Flats National Wind Technology Center and 59 mph at the NCAR Mesa Laboratory…3 miles southwest of Boulder. West winds gusted to 43 mph at Denver International Airport.

In 2011…a powerful early season storm brought heavy snow to the Front Range and adjacent plains. The heavy…wet snow caused extensive downed large branches and in some cases…entire trees. Massive power outages occurred from Fort Collins and Greeley south to Denver and the surrounding metro area. Most of the trees still had their leaves…which helped to catch snow and down trees under the weight of the moisture laden snow. Nearly two hundred thousand utility customers along the Front Range were without heat and electricity for several hours. The Red Cross opened four temporary shelters overnight until the power could be restored. The outages also forced the closure of the Boulder Criminal Justice Center the following day. The fallen trees and branches also caused extensive property damage to roofs and automobiles. In the Front Range mountains and foothills…storm totals included 19.8 inches…3 miles west of Jamestown; 18 inches…5 miles west of copper; 13 inches…3 miles north of Blackhawk and 3 miles south of Evergreen…4 miles east-northeast of Nederland and Lake Eldora; 12 inches at Berthoud SNOTEL. Across the urban corridor storm totals included: 11.5 inches in Boulder; 9.5 inches at the national weather service in Boulder; 9 inches…1 mile southwest of Westminster; 8.5 inches in Broomfield… Denver International Airport…Frederick and Louisville; 8 inches in Aurora…7 inches in Watkins; with 6 inches in Arvada.

25-26

In 1996…4 to 6 inches of snow fell in the foothills west of Denver. Only 1.5 inches of snowfall were measured at the site of the former Stapleton International Airport on the 26th. This was the only measurable snow of the month at the site. The snowfall produced icy and snowpacked highways…which resulted in a 50-to 60-car pileup on I-25 south of metro Denver. West winds gusted to 33 mph at Denver International Airport.

In 2006…a winter storm brought heavy snowfall to metro Denver and the eastern foothills. Total snowfall ranged from 12 to 22 inches over the higher terrain and 6 to 12 inches across metro Denver. Northerly winds at sustained speeds of 20 to 30 mph with gusts as high as 47 mph at Denver International Airport whipped the snow into drifts 3 to 4 feet deep. Many tree limbs snapped under the weight of the heavy…wet snow which also downed power lines… Leaving thousands of residents without power. Storm total snowfall included: 25 inches near Aspen Springs…Conifer… And Evergreen; 23.5 inches near Rollinsville; 23 inches in Idaho Springs; 22.5 inches near Blackhawk; 21.5 inches near Bailey; 19 inches near Bergen Park; 18 inches near Aspen Springs…Genesee…and Jamestown; 17 inches southwest of Boulder; 16 inches in Evergreen; and 15 inches near Georgetown and Perry Park. Snowfall totaled 5.3 inches in the Denver Stapleton area. At Denver International Aiport…rain…including a thunderstorm…changed to snow on the evening of the 25th after a high temperature of 70 degrees.

In 2010…a storm system brought heavy snow to the mountains west of Denver. Storm totals included: 24 inches at the Eisenhower Tunnel…18 inches at Loveland Ski Area; with 16 inches at Arapahoe basin.

25-27

From a random anniversary gift to becoming Colorado’s longest running independent source for weather news and data. Crazy, eh?

It was 19 years ago on October 25, 2006, that ThorntonWeather.com went live and the first bits of live weather data from our weather station were fed to the Internet.

My wife had gotten me a home weather station for our anniversary a few months earlier. It was fun to be able to see what the weather conditions were right where we lived in Thornton – not DIA or downtown Denver where conditions can be dramatically different.

It didn’t take long though and I soon desired more. I wanted to be able to monitor that weather station from anywhere and thus, with the help of the home weather station community, created the first version of the website.

  • Did you know ThorntonWeather.com is a completely non-profit venture run by a Thornton resident?  We are self-funded but do occasionally receive help from members of the community, something which allows us to keep things up and running. Learn more about how you can help here.

Word soon got out among residents of the north Denver metro area and traffic to the site boomed. Stories in print media helped spread the word.

We are proud to have become a valuable resource for the community providing real time weather data, forecasts, historical climate information, satellite imagery, webcams and so much more.

We’re just ‘weather geeks’ that love the weather and love our community.  Running ThorntonWeather.com can be a bit expensive and it is time consuming to maintain and operate it but it is worth it.

We’d like to thank all of our visitors for your support in the past and we look forward to continuing to be the best, truly local source for Thornton weather.
