In explaining summer discomfort, they say it’s not the heat but the humidity. And there was humidity aplenty in Washington on Saturday but so little heat that it still seemed to be pleasant enough.

In the District, the high was 76 degrees, the coolest in more than two months. The last cooler day as measured at Reagan National Airport was June 21, when the high was 75.

At Dulles International Airport, it was a good deal cooler, with a high of 71. Dulles, well to the west of the Capitol dome, has often been considered too far off to truly represent the region, but now it is only four or five miles beyond the end of Metro’s Silver Line.

Dulles has known no cooler day since May 29, when the high was only 59.

Full enjoyment of the day did demand a tolerance for clouds and rain, or an ability to time outdoor activity to miss the periods of downpour.

At Dulles, 0.83 inches fell, and the rainfall was heavy at times at Reagan National, skies were also gray, but only a bit more than one-fifth of an inch of rain was recorded.
