A strong winter monsoon struck, and Hong Kong dropped significantly today (26th). It is expected that the highest temperature during the day is still 19 degrees Celsius, but it drops by 7 degrees to 12 degrees at night. The coolness in the New Territories is even worse. The Observatory issued this year at 11 am The first cold weather warning since the beginning of winter. Later, strong winds, overcast weather and rain, the wind chill effect becomes more obvious.
The Observatory predicts that the high-altitude disturbance will bring cloudy and rainy weather tomorrow (27th). The urban area will further drop to 9 degrees, and Taguling may only be 4 degrees. It is expected that the cold weather will continue until Tuesday (28th). Please remember when you go out. Take care to keep warm.

Tai Mo Shan fell to 6.4 degrees before noon
Affected by the strong winter monsoon, the temperature in most parts of Hong Kong at noon was about 5 degrees lower than yesterday, of which Tai Mo Shan had dropped to 6.4 degrees before noon.
According to the Observatory, it was cloudy with a few rain patches today, and the weather became significantly colder. The temperature in the urban area gradually dropped to the lowest of about 12 degrees tonight, and the New Territories were a few degrees lower, with fresh north-northeast winds, and occasional strong winds from offshore and highlands.
The Observatory issued its first cold weather warning this morning, setting a record for the fifth late in the winter
The Observatory issued the first cold weather warning since the beginning of winter in the morning, setting a record of the fifth late.
Looking at the data, since the cold weather warning system came into effect in December 1999, there have been 4 winters when the cold weather warning was issued on or after December 27. The first one occurred in 2007 at the latest, and it was only on December 30 that year. Issued the first cold weather warning after the beginning of winter.
As of 11 am, the temperature in Tai Mo Shan had dropped to 6.4 degrees.

Tomorrow it will get colder and Tai Po and other 7 districts will fall to the "severe cold" level
The Observatory predicts that the high-altitude disturbance will bring cloudy and rainy weather tomorrow. It is expected that Hong Kong will be cloudy with occasional rain. Initially, strong winds are blowing offshore and on high ground. The lowest temperature in the urban area is only 9 degrees.
With reference to the automatic regional weather forecast, it is expected that the temperature in at least 7 districts will drop to the "severe cold" level (7 degrees or below) tomorrow. Among them, Ta Kwu Ling is the coldest, with the lowest temperature of only 4 degrees.
The Observatory expects the cold weather to last at least until Tuesday, but the minimum temperature rose slightly to 11 degrees. Coupled with the high-altitude disturbance away, the sky was clear and dry during part of the day.
With reference to the automatic regional weather forecast, the temperature is expected to drop to "severe cold" levels in at least 7 districts tomorrow.

The Observatory has explained that it is extremely cold in rainy days, because water has a higher thermal conductivity than air, and the water points attached to the body are easier to lose heat from the body.
When exposed to the sun on a sunny day, it will absorb the heat of the sun and offset the loss of part of the body's heat. It feels warmer, but on a cloudy day it feels the opposite.
Therefore, in winter on cloudy and rainy days with strong winds, the feeling of cold will be more obvious, and the temperature felt (that is, the body temperature) will be lower than the actual temperature measured by the instrument, which is called the "wind chill effect."

Facing the approach of the new year, the Observatory predicts that New Year's Day (January 1) will continue to be sunny, and then the sun will gradually diminish and rain will begin.
