Shanghai's Early Heatwave to Give Way to Sudden Cold Snap

Shanghai Experiences Early Heatwave Followed by Cold Snap

Shanghai has witnessed an unusually early heatwave, with temperatures reaching 30°C on Tuesday, March 14th, 2023. This marks the earliest recorded 30°C temperature since 1933, according to The Paper.

However, a sharp change in weather is expected within the next two days. The China Meteorological Administration (CMA) predicts a significant drop in temperatures, with a decrease of 12-17°C and lows reaching 8°C.

The Shanghai Xujiahui Meteorological Station recorded a temperature of 30.4°C by 12:40 pm on Tuesday, making it the second-highest daily temperature ever recorded in March. Temperatures in Pudong and Minhang also exceeded 30°C and continued to rise.

Historically, Shanghai's first day with temperatures exceeding 30°C typically occurs in late April or early May. This early occurrence in March is exceptionally rare. In the station's 150-year history, only two previous instances – March 20, 1933, and March 31, 1945 – had recorded temperatures reaching or exceeding this mark.

Starting Wednesday, the weather is expected to turn cloudy with occasional showers. As cold air moves into Shanghai, temperatures will drop rapidly, with lows falling below 10°C by Friday.
