When is Denver going to hit 100 degrees?
For Denverites watching the weather forecast creep toward triple digits, there may be a few more weeks reprieve before temperatures on Colorado’s Front Range hit 100 degrees.
“So far this year we’ve had three 90-degree days, and we average at least one 100 degree day almost annually in Denver, so we’re just waiting to see that heat really build,” said Greg Heavener, warning coordination meteorologist with the National Weather Service’s Boulder office. “It doesn’t really look like in the next week or 10 days we’re going to get there.”
Hitting 100 degrees this early in June isn’t unheard of in Denver — the city’s earliest daily record high to hit 100 degrees was June 11, 2022, according to NWS data. But the three hottest June days on record all hit 105 degrees later in June in 2012 and 2018.
“Usually we see heat peak in late June and early July,” Heavener said. Humidity from the monsoon season, which typically starts later in July, may keep things a little cooler as the summer progresses, he added.
Denver’s most recent 100-degree day was July 9, the only time the weather hit triple digits at Denver International Airport in 2025, according to the weather service.
Unlike lower elevations in Colorado, seeing multiple 100-degree days is relatively rare in Denver, NWS data shows. Even having two can earn a spot on the agency’s list of the greatest number of 100-degree days in a year.
The top spot belongs to 2012, when Denver recorded 13 days of 100 degrees or hotter. That’s the same year Denver saw a five-day streak of 100-degrees or hotter in late June. Two other heat waves tying the No. 1 spot happened in July 2005 and 1989.
Folks hoping for an early cool-down from the coming El Niño will be disappointed, Heavener said. The weather pattern doesn’t have much of a connection to summer weather in Colorado, and its influence is more pronounced in the fall and winter months.
On the flip side, Denverites who want to bake in the sun even sooner can take a road trip south or west on Wednesday, when forecasters expect temperatures to exceed 100 degrees in Grand Junction, Pueblo and La Junta.

What about other races on 2026 Colorado primary ballots?
Every other non-statewide race on the Democratic and Republican ballots is uncontested in the primary.
Who can return ballots in the 2026 Colorado primary election?
Remember that anyone who is registered as a Republican or Democrat can return only their party’s ballot.
Unaffiliated voters may choose which of those ballots to return, but only one can be returned. If both are returned, neither will be counted.
Two other parties are holding primary elections, with the Libertarian ballot including just candidates for secretary of state and the Unity ballot including just candidates for governor. Those ballots can only be returned by party members.
Voters registered for a party without a primary will not receive a ballot.
