It’s no secret that March was a warm one around Colorado and the Mile High City was no exception. According to the National Weather Service, numerous temperature records were smashed in Denver last month, including that this past March was the warmed March the city has ever experienced with records dating back to 1872.

During March 2026, the average temperature in Denver was measured at 51.6 degrees Fahrenheit – not only would this have been the 15th warmest April on record, it was also enough to topple the previous warmest March in the city – that of 1910, which had an average temperature of 50.4 degrees. The 1.2-degree gap between the prior record and the new one might not seem like much, but what’s now the 3rd-warmest March in city history was 49.2 degrees on average, more than two degrees lower than this year’s record setting average temperature. What’s now the 10th-warmest March on record was 46.4 degrees on average, set in 1946 and a full five degrees lower than the record set this year. The comparison to the coldest month of March in Mile High City history is shocking, too – March 1912 had an average temperature of just 26.4 degrees.

Also shocking is that March brought eight days where the high temperature topped 80 degrees – the previous record was set at three days in March of 1907.

Meanwhile, another record that was broken was the average high temperature of the month – 67.6 degrees this year compared to the prior record of 65.5 in 2012. It’s also worth noting that a new ‘daily high’ record was set on five dates (March 19, 20, 21, 24, and 25), with another date tying the record high of previous years (March 29). March of 2026 also brought the highest temperature ever record in Denver in March – 87 degrees on March 25.
