Cooler temperatures and showers arrived last night.

The high temperature is expected to drop to 25 degrees Celsius today and tomorrow with lows around 22 degrees, while the mercury will fluctuate between 22 to 27 on Wednesday and Thursday, the Shanghai meteorological bureau said.

More showers are likely over the next four days.

But the city is still officially in summer as the meteorological start of autumn requires five consecutive days of average temperatures below 22 degrees.

Yesterday was cloudy and rainy in some areas but with highs still over 30 degrees.

Summer officially began on May 7 this year, 157 days ago.

Another cold front is expected to hit the city on Friday.
