On the 26th of August, 2012, Denver, CO tied the record for the most number of 90°F+ days at 61!
After setting the record for the hottest July in Denver history and a very warm start to August, 8 out the past 10 days were below 90°F. The past week and a half has felt very, very comfortable when compared to the record number of 100°F+ days recorded in June and July (13).
What is the difference between that record-setting July and August 2012? July’s average temperature was 78.9°F! The average temperature through 25 days in August 2012 is only 74.1°F, or 4.8°F cooler. The biggest difference hasn’t been the maximum temperatures, it has been the minimum temperatures: instead of high 60s, nightly low temperatures have been much more comfortable in the high 50s.
The record number of 90°F+ days will fall – that is certain now. The next three days are all forecasted to be 90°F+, and Thursday’s forecasted high of 89°F will also obviously challenge 90°F. 90°F+ days can also occur in September, so the total number may not be recorded on Wednesday.
While August 2012 will not be in the top-10 warmest all-time, it just might challenge the 4th-driest August on record. Current month-to-date precipitation is only 0.11″. 1924 was the driest at 0.02″, 1900 and 1917 were 2nd driest at 0.05″, and 1960 was 3rd driest at 0.06″. Just behind 2012 is 1974 at 0.16″. It won’t take much of a rainstorm to boot 2012 out of the top-10, however. The 10th-driest year one record is 1985 at 0.28″. It does not look likely at this time that any additional precipitation will be recorded at Denver.
