While the majority of the month has been submerged in the summer swelter, we’ve had a few snags along the way that have mixed in record cool temperatures amidst a record hot July!

Barreling through July on a record hot pace, it's hard to believe we’ve swung the pendulum just the opposite way to record cool weather, too, not once but twice!

The average monthly temperature at Reagan National Airport in July is 84.7 degrees, which is a whopping 4.9 degrees above average. This is on par to becoming the hottest July on record in the nation’s capital (see below). What’s even more… this includes two days (Saturday included) with rock bottom “cold” temperatures amidst a sweltering month. The following includes all of the daily record temperatures set during the month so far:

Record Coldest High Temperatures
July 21: High temperature of 71 degrees defeated the coldest high temperature of 74 degrees

Record Warmest Low Temperature

July 2: Tied for the record high minimum temperature of 73 degrees

July 18: 80 degrees defeated the former record of 79 degrees

Record High Temperatures
July 7: 105 degrees defeated the former record high of 102 degrees set in 2010 and tied for the second warmest high temperature of all-time in Washington.
July 8: 102 degrees defeated 100 degrees set in 1993
July 5-8: Four in a row 100 degree days ties the record for consecutive 100 degree days set in July 1930

Now, with only nine days left in the month, Washington could easily have the warmest July on record.

Record Warmest July at Reagan National Airport (average temperature):
1. 2012 (84.7 degrees so far)
2. 2011…84.5 degrees
3. 1993 and 2010…..83.1 degrees
4. 1999…..83.0 degrees
5. 1987…82.5 degrees
6. 1872….82.3 degrees

Temperatures will climb above average early next week before a front returns them back to near average by the middle of the week. Looking ahead through July 31, temperatures will likely trend above the average high of 89 degrees but no major heat waves like we saw so far this month are in the offing.
