As of the September 1, 2012, there have been 67 90°F+ days – far and away the record number for one calendar year. That is 6 more than the previous record of 61 set in 2000!
Here is the breakdown of 90°F+ days per month in 2012 (to date):
17 in June (6 of those were 100°F+ days; 2 of those tying Denver’s all-time maximum temperature of 105°F)
27 in July (7 of those were 100°F+ days)
20 in August (thankfully none of them 100°F+ days, although 4 of them were 98°F and another 3 were 97°F)
August 2012 went down in Denver history as the 5th warmest and 4th driest on record. The average temperature for the entire month was 75.0°F, 2°F cooler than August 2011. The total rainfall for the month occurred during one storm – 0.11″. That monthly total is 1.58″ below the monthly average and 0.09″ more than the driest August on record in 1924.
Today and the next two days are forecasted to be 90°F+, followed by two days of mid-80s. It would be incredibly significant if 2012 recorded 1/6 more 90°F+ days as the previous record. This week might not see all of the 90°F+ days (although I certainly hope they end on Tuesday!) as short heat waves can set up in mid-September. Many folks along the Front Range are looking forward to autumn.
