Houston - Recent August Temperatures and Rainfall





The numbers here describe what the August weather in Houston, Texas was like for every year since 2010. A series of tables gives August 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 August. Then there's information on how much rain actually landed this month during recent years, as well as how often Houston had wet weather.
