As we take a look back at July, one thing is clear: there was little in the way of unusual weather across the region. No huge heat waves, no record cold ... just characteristic, muggy mid-summer weather. What follows is a summary of the weather statistics at the different airports during July.
Temperatures and rainfall at Reagan National Airport (DCA) weren't too far from normal for July. The average temperature of 80.7 degrees was 1.5 degrees above normal. Fourteen of the last 15 months have now been warmer than average at DCA. No record highs were set but record high low temperature records were tied on July 30 and 31 when overnight readings only dipped to 78 degrees. There were 14 days with temperatures of 90 degrees or hotter; which is close to average. Precipitation was likewise near average as 3.60 inches of rain fell compared to the normal July rainfall of 3.66 inches.

Dulles Airport's temperatures were also a little above normal but it was dry. The average temperature of just under 77 degrees was a little over a degree above normal with no daily records set. There were 11 days with temperatures of 90 degrees or hotter; which is just under the normal of 12 days. Only 2.18 inches of rain fell compared to the normal July average of 3.57". This places July 2008 as the 9th driest on record at IAD.
Further north, Baltimore-Washington International Marshall Airport (BWI) observed both above normal temperatures and rainfall. The average temperature was 77.5 degrees, one degree above normal. However, only 10 days reached 90 degrees or higher which is two below normal. The airport did hit a record low on July 25 of 59 degrees. Above normal rainfall was recorded as 5.47 inches fell, an inch and a half above normal. There were two daily rainfall records set, as well.
So, all in all, fairly typical July conditions prevailed across the area.
How will August turn out?
