A History of 100 Degrees in the Twin Cities

The last time the mercury hit 100 degrees at the Twin Cities International Airport was on July 6, 2012 with 102 degrees.

It's been relatively uncommon to see the mercury reach 100 at the Twin Cities International Airport in recent years. Before 2012, the last time the maximum temperature was 100 degrees or more was on June 7, 2011 when the air temperature reached was 103 degrees. Looking back to 1873, the maximum temperature at the Twin Cities official measuring site has reached 100 or more on 65 occasions. The most was in 1936 with nine days.

Twice in one week, the mercury hit 100 degrees or higher at the Twin Cities International Airport in July 2012. The last time there were more than two 100 degree maximum temperatures in the Twin Cities in a year was 1988, when there were four.

Below is a table of all the dates since 1873 of days where the temperature was 100 or more at the official Twin Cities observing site.
