In the weather world, there’s a term you probably haven’t heard before – ‘WeatherGami,’ and it deals with how often a specific high temperature of the day is matched with a specific low temperature of the day. It’s perhaps best described by the graph shown at the top of this article, which depicts a series of dots placed on the graph considering daily minimum and daily maximum temperatures of each date.

Data goes back to 1872, with the frequency of max/min temperature occurrences are carefully tracked over the past 152 years.

While a high of 84 degrees and a low of 56 degrees has been recorded 92 times over that century-and-a-half-plus period, the unique combination of yesterday’s high of 43 degrees and low of -2 degrees in the area of Denver International Airport has never been recorded before, according to the National Weather Service.

That’s pretty wild considering that the graph depicting all daily temperature recordings between 1872 and 2024 would contain around 55,000 data points.

So, congrats, Denverites! Even though you probably didn’t even notice at the time, you have officially experienced a one-of-a-kind weather day in the Mile High City.
