An exceptionally dry, sunny and warm November
Under the prevalence of the dry northeast monsoon, the weather in Hong Kong was fine and dry from November 1 to 11. With plenty of sunshine, the maximum temperature at the Hong Kong Observatory rose to 29.3 degrees on November 1, the highest of the month. Following the moderation of the northeast monsoon, it was mainly cloudy with sunny intervals on November 12. A cold front formed over the northern part of southern China on November 13 and moved across the coastal areas that night. The associated northeast monsoon brought generally fine and slightly cooler weather to Hong Kong from November 14 to 17.
Meanwhile, another cold front formed over central China on November 17 and edged southwards gradually. It moved across the south China coast in the night of November 18. Locally, apart from some haze, the weather in Hong Kong remained fine and dry on November 18. The northeast monsoon behind the cold front brought cooler mornings to the territory with the minimum temperatures staying below 20 degrees in the next four days. As the northeast monsoon weakened, local temperature recovered gradually on November 23 and 24.
The strengthening of the northeast monsoon brought windy weather to Hong Kong on November 25. After a cloudy day on November 26, the weather turned fine again on the following day. With the replenishment of the northeast monsoon reaching the south China coast on November 28, it was fine and dry with cool mornings in Hong Kong from November 28 to 30. The temperature recorded at the Hong Kong Observatory on the morning of November 29 was 17.0 degrees, the lowest of the month.
Six tropical cyclones occurred over the South China Sea and the western North Pacific in November 2019.
