Shanghai records rare high temperature amid rainy season

On Thursday morning, the city's major meteorological observatory issued this year's fourth yellow alert for high temperatures, the third-highest alert in China's four-tier color-coded weather warning system. Shanghai is experiencing a rapid temperature rise and is expected to encounter a maximum daily temperature of over 35 degrees Celcius.

On June 17, Shanghai entered the annual plum rain season earlier than usual. After two rounds of heavy rainfalls, the city began undergoing a temperature rise. On Wednesday, Xujiahui weather station in the city proper reported that its maximum temperature reached 35.8 degrees Celcius, making it Shanghai's second high-temperature day this year.

Usually, it is rare to see such high-temperature days during the city's rainy season in summer. However, Shanghai has recorded more and more hot days since the late 1980s. Over the past decade, it experiences about two high-temperature days every plum rain season on average, said the city's weather authorities.

The good news is that Shanghai will still be affected by the rainy season, as starting from Thursday, the city will go through a two-day strong convective weather, with lightning, thunderstorms, and even hail in some parts.
