Hong Kong will experience cooler weather next week, with the temperature expected to fall below 20 degrees Celsius on Sunday under the influence of a northeast monsoon.

The Hong Kong Observatory on Saturday said a fresh to strong northeast monsoon would persist over the coast of southern China in the next couple of days, with slightly cooler weather in the region, while a band of clouds would bring showers.

The next few days are expected to be slightly cooler with a few rain patches before daytime temperatures rise again mid-next week, according to the weather forecaster.

Cloudy weather and rain patches will continue into Sunday, when the temperature is expected to drop to 19 degrees, with a maximum of 21 degrees, according to the forecaster.

Regional temperatures in Cheung Chau, Lau Fau Shan and Ta Kwu Ling are expected to plunge to a low of 17 degrees on Sunday.

The temperature is predicted to fall between 20 and 23 degrees on Monday, before climbing gradually to reach as high as 27 degrees on Saturday next week.

Temperatures fell between 20 and 23 degrees on Saturday, with mainly cloudy and slightly cooler weather expected for the afternoon and in the evening with one or two rain patches.

Earlier this week, Severe Tropical Storm Nalgae prompted a No 8 typhoon warning signal on Wednesday, the first to be issued in November in 50 years, which brought cooler temperatures, strong winds and rough seas.
