Washington DC - Recent July Temperatures and Rainfall





The numbers here describe what the July weather in Washington DC was like for every year since 2010. A series of tables gives July data by year for temperature and precipitation.

They begin with average maximum and minimum temperatures in degrees Fahrenheit and Celsius. That's followed by how many really hot days occurred each July. Then there's information on how much rain actually landed this month during recent years, as well as how often Washington had wet weather.

The climate data come from weather measurements made at the Reagan National Airport near downtown Washington.
