SHANGHAI is in for a mixed week of fluctuating temperatures and intermittent drizzle with hanlu (cold dew) season, which began yesterday.

Today and tomorrow are forecast to be cloudy, but the maximum is expected to touch 30 tomorrow before turning cooler as a cold front comes in from the north and brings drizzle, the Shanghai Meteorological Bureau said on Sunday.

The high is expected to drop to 24 on Wednesday and 20 on Thursday.

The city’s environmental monitoring center says air quality will remain excellent for the first half of the week. Yesterday marked the start of the solar term hanlu, and the weather will get steadily cooler, so get those coats out of the closet and rug up.

Hanlu, one of China’s 24 solar terms, indicates colder temperatures will condense the dew into frost. But people still have to wait before autumn comes meteorologically — that will be when the average temperature falls below 22 degrees Celsius for five straight days.
