But beside from a simple“hot”, what other ways are there to describe the summer heat? Apart from phrases like“boiling hot”, there are many interesting expressions that relate to unbearably hot weather.

　　Dog days of summer

　　In books and newspaper articles, the period from early July to mid-August is often referred to as the“dog days of summer”. Some think the expression means the weather is so hot that dogs go wild. But in fact, the expression comes from 16th century and refers to the days on which Sirius(天狼星)—the Dog Star—rises at the same time as the sun. The Romans associated the hot weather with this star and would sacrifice a dog every year in April to stop the anger of Sirius.

　　So hot you can fry an egg on the sidewalk

　　This expression needs no explanation and although its origin is unclear, it hasn’t stopped thousands of curious tourists from testing if the saying is true, with the result that sidewalks in Death Valley, California—the hottest place in the US—are now littered with broken eggshells. Early in July, the local government asked tourists to stop their cooking experiments. Even so, it is actually possible to fry an egg on the sidewalk, so long as you use a frying pan with a lid and the temperature is at least 49℃.
