People who live here expect August in the Washington, D.C. area to be hot, humid, and horrible. It often is. Daily high temperatures above 90°F are common, relative humidity above 90% is also common. Nightly lows above 80°F are not uncommon. However, on average you should expect high temperatures in the 80s and lows in the 70s with a slight breeze. In other words, hot but far less horrible than the folklore would have you believe.
Washington sometimes has dramatic thunder storms in August, and a hurricane is possible (although unlikely). For more details, see What is Washington, D.C.’s weather like in August?
While it will probably be hot outdoors it may be chilly indoors. Air conditioning is used both to cool and to dry the air. This means that it is sometimes too chilly indoors for people dressed for the outdoors. Bring a light sweater or jacket; you may want it.

Getting Around in Washington
Do what the locals do: Take the Metro!* The hotel is at the Rockville stop of the Red Line. (The hotel doors are closer to the entrance to the Metro* than the Metro parking lot is.) BUT, be aware that throughout 2017 parts of the Metro* system will be disrupted!
Metro Maintenance 2017
The DC Metro is in the midst of a major program of emergency repairs and maintenance called "SafeTrack". "SafeTrack" will bring many advantages in the long run, but since the program began in 2016 it has brought inconvenience to the parts of the system being worked on at the time. The SafeTrack schedule for the summer of 2017 has not yet been announced. However, we strongly suggest checking the "SafeTrack" site before using Metro in 2017.
