Hongkongers will enjoy a relatively warm Christmas with a high of 24 degrees Celsius, but temperatures are expected to plunge to 11 degrees by New Year’s Eve.
The Observatory said on Monday that temperatures will rise slightly over the Christmas holidays and the weather will be brighter. Christmas Day is expected to have a high of 21 degrees and a low of 18 degrees.
Boxing Day will be even warmer, the Observatory said, with a high of 24 degrees and a low of 19 degrees.
However, the latter part of the week will come with rain, wind and a significant fall in temperature.
“An intense winter monsoon will reach the South China coast in the latter part of this week,” the Observatory said.
The days immediately before and after the new year are all expected to have a high of 14 degrees and a low of 11 degrees.
“An area of low pressure now to the east of the Philippines is expected to develop gradually. It may enter the central part of the South China Sea during the weekend,” the Observatory added.
The city had just experienced an unusually warm winter solstice – the shortest day of the year – on Saturday, with a mean daily temperature of 22.2 degrees.
It was the warmest winter solstice on record.
