Hong Kong experienced a cold snap over the weekend and while temperatures are expected to pick up slightly in the latter part of this week, cold weather is forecast to return next week.
The Observatory issued frost warnings again on Sunday afternoon and it expects that ground frost will reoccur early next Monday morning in the New Territories.
Reporters from HK01.com went to farms at Lee Uk Tsuen in Ta Kwu Ling, in the north of the New Territories, and found a temperature of 6.4 degrees Celsius at 6am – but no frost.
At 8am, the temperature in urban areas was 8C. But at Tai Mo Shan, the highest peak in Hong Kong, it was minus 1.8 degrees.
Forecasters at The Observatory expect Hong Kong to experience cold and dry weather over the next few days with minimum temperatures ranging from 8 to 12 degrees Celsius.
It should warm up over the coming weekend when the temperature will reach about 18C on Saturday.
However, the winter monsoon will affect southern China early next week, so temperatures will drop to 12 degrees or lower, they said.
