DENVER — The hottest day of 2016 in Denver has been 90 degrees, which has happened three times: June 10, 11, and 16. And the 90s remain in the outlook for the next several days.

This streak will likely end Monday when things cool a bit.

With the arrival of the 90s, I felt it time to review how many 90s Denver International Airport has each year to put things into some perspective; DIA is the official weather reporting station for the city.

DIA came online in mid-1994. In its 20 full summers of data, DIA has an average of 43 90-degree days per year. In 2015, there were 48 such says, yet 2014 was cooler with only 29 90-degree days.

That is for the total number of 90-degree days per year. Here’s the top 10 occurrences of consecutive 90-degree days:

  1.  24 days in 2012
  2.  24 days in 2008
  3.  18 days in 2011
  4.  17 days in 2000
  5.  15 days in 2012
  6.  13 days in 2002
  7.  12 days in 2005
  8.  12 days in 2003
  9.  12 days in 2000
  10.  11 days in 2007

It will remain to be seen if any top-10 consecutive 90-degree day records are this year or if the average of 43 days per year is beat. Certainly both will be possible with the much warmer than average temperatures so far in 2016.

If you are interested in a longer history of the city, there are the same comparisons for the Stapleton site, which goes back to 1948 as Denver’s former official weather location at
