Hongkongers woke up to cooler temperatures on Friday, with the mercury plunging by about seven degrees to a minimum of 15 degrees Celsius (59 Fahrenheit), the lowest so far this Autumn.

The Observatory said it recorded around 15 degrees in urban areas in the morning, marking a decrease of six to seven degrees compared with Thursday, while the mercury dipped even further in the New Territories.

“Under the influence of an intense northeast monsoon, the weather is generally fine over the coast of Guangdong,” the forecaster said. “It became cool appreciably. The maximum temperature will be around 22 degrees during the day.”

The forecaster said the weather could become warmer next week as the monsoon weakened, leading to a gradual rise in temperatures over the Guangdong region.

Jessica Leung Ngai-sui, a scientific officer at the Observatory, said a sudden chill in November was a normal occurrence.

“Based on past data, the temperature in early November last year dropped to about 18 degrees and about 16 degrees in mid-November 2021,” she said.

Relative humidity will also drop to a minimum of 30 per cent on Friday and Saturday, with the highest reaching 55 per cent.
