Hong Kong is set to brave a chill over the next few days, with temperatures projected to plummet as low as 13 degrees Celsius on Friday.

And a strong stream of moist air from the east had shrouded the city in mist by Tuesday morning, pushing visibility in the harbour below 5,000 metres.

The Observatory issued a strong monsoon signal at 9.45am.

The weather was forecast to remain cloudy throughout Tuesday and Wednesday, with cooler weather and a few patches of rain.

“Morning temperatures will be around 12 and 13 degrees in the following few days,” the Observatory said.

The lowest temperature from Tuesday to Thursday was projected to be around 17 degrees, dropping to 13 degrees on Friday and Saturday and dropping again to 12 degrees on Sunday.

The temperature will not pick up until next Tuesday, the Observatory forecast.

Forecasters said the cold weather had arrived with a northeast monsoon associated with a cold front, which would reach the south China coast on Thursday.

Observatory scientific officer Leung Yan-yu said northeast monsoons often hit the coast in February and March, causing cold weather.

“This sudden drop in temperature is normal,” Leung said.

She added that there could be heavy rain on Tuesday evening and Wednesday morning, reminding Hongkongers to carry an umbrella.
