Temperatures in Beijing could rise to more than 35 C from Wednesday to Friday, the city's meteorological center said on Tuesday as it released a yellow alert for high temperatures.

It is the capital's first alert for high temperatures this year. It advised people to take precautions against heat stroke and fire, especially around midday.

Beijing officially entered the summer season on May 7 this year, 12 days earlier than the average date, the center said. Meanwhile, Beijing's spring, which started on March 26, only lasted one and a half months.
