Denver logs second-warmest December on record

Denver broke seven weather records last month and came close to breaking the record for warmest December in city history, according to the National Weather Service.

By the time the clock struck midnight on New Year’s Eve, transitioning Denver into 2026, Denver had officially recorded its second-warmest December on record, according to the weather service.

Cold spells at the beginning and end of the month kept the city from breaking the overall December record, meteorologists said.

But the city still broke daily temperature records seven times in the month, including on Christmas Eve and Christmas. It also documented 21 days where the average temperature was more than 6 degrees above normal, according to the weather service.
