Why are these hot, humid days of August called Dog Days?
These days are named for the Dog Star, Sirius, in the constellation Canis Major. This star starts shining brightly at this time of year. It rises in the east at about the same time as the Sun. The ancient Egyptians thought that the star was responsible for the heat and blamed it for any droughts, sickness, and discomfort that occurred. The Dog Days traditionally start on July 3 and end on August 11, which may or may not be when the hot, humid weather ends.
