The temperature in Beijing in July

You can refer to the current weather in Beijing. On July 6, the temperature in Beijing hit a record high, reaching more than 40 degrees in some areas. July 7th is the solar term in summer. After the light summer, the rain will increase. By then, Beijing will be a "sauna day", wet and hot. I don't think it's necessary to have long sleeves, as long as you don't get heatstroke. Of course, it is still cool after midnight. If you go out at night, thin women can take a thin coat, but men don't need it.
