Hongkongers will be feeling the chill as a cold snap is set to descend on the city in the coming week, with temperatures expected to drop to 12 degrees Celsius.

The northern monsoon has descended over southern China and is moving gradually towards the city, the Observatory said on Thursday afternoon. It is forecast to grip the coast of Guangdong on Friday.

An intense monsoon will persist over the coastal areas over the coming days.

“The weather will become cool significantly over the region,” the Observatory said. “Temperatures will drop further over the region, it will be cold early to midweek next week.”

Monday and Wednesday are set to be the coldest days with temperatures as low as 12 degrees Celcius.

Temperatures are expected to drop to between 17 and 21 degrees Celcius on Friday, with lows of 13 degrees Celcius expected over the weekend.

The rest of the week will be cloudy with one or two patches of rain and sunny intervals.

“The temperatures are expected to drop in the following days so it is time for the public to prepare for the winter weather,” scientific officer for the Observatory, Chong Sze-ning, told HKFP.

The Observatory said last month that, owing to the warming of the central and eastern equatorial Pacific, the region is likely to remain warmer than normal over the coming months.
