Washington, D.C. – The summer of 2025 closed as one of the driest in more than a decade for the nation’s capital, with Reagan National Airport recording just 9.22 inches of rain between June and August. That total made it the driest summer since 2012, according to the National Weather Service Baltimore/Washington.
Across the region, rainfall and temperatures told a mixed story. Baltimore/Washington International Airport logged 10.91 inches of rain, more than an inch below normal, while Baltimore’s average high temperature of 85.8 degrees made it the city’s coolest summer since 2017. At Washington Dulles International Airport, highs averaged 86.0 degrees, the coolest since 2018, with rainfall also coming in nearly an inch and a quarter below average.
Farther west, Martinsburg, West Virginia, saw its mildest overnight lows since 2020, averaging 64.0 degrees, while summer rainfall reached 12.03 inches, slightly above normal. Charlottesville, Virginia, stood out as the wet spot, picking up 12.80 inches of rain—more than an inch and a half above average—while posting its coolest average high temperature since 2015.
In sharp contrast, Hagerstown endured a notably dry stretch with just 6.16 inches of rain, the city’s driest summer since 2020.
Forecasters note that while temperatures across much of the region trended slightly cooler than recent years, rainfall deficits in key metro areas could impact soil moisture heading into fall. Additional seasonal updates will be issued later this month.
