Denver hits three consecutive 100-degree days: Here’s how unusual this is

DENVER — Denver will have the potential to make July weather history later this week as a large ridge of high pressure moves in from the west. It will bring multiple days with highs in the upper 90s and low 100s starting on Thursday. 

As it stands right now, we will have the potential to see 100 degrees in Denver for at least three days in a row starting on Friday. If that happens, it will snag a unique place in Denver weather history.

Since 1872, there are only 15 instances of the city’s official weather station hitting 100 degrees on consecutive days. Most of those happened during the month of July, and most have been since the year 2000.
