Climate of Hong Kong

Climate of Hong Kong

Hong Kong has a warm maritime climate (type Cwa according to the Köppen-Geiger classification). The climate, described as subtropical according to many other sources, is characterized by warm, relatively dry winters and tropically warm summers with a lot of precipitation and high humidity. Because the coolest month has an average daily temperature that is below eighteen degrees, Hong Kong is not eligible for tropical A climates.

Temperature & Sunshine

Hong Kong has an average maximum temperature of 25.6 degrees Celsius and a minimum temperature of 21.1 degrees, measured over the entire year. January is the coolest month, with an average of 18.6 (max.) and 14.1 (min.) degrees. July is the hottest month, with an average maximum of 31.3 degrees and an average minimum of 26.7 degrees. This month is also the sunniest, with 214.9 hours of sunshine (over 7 hours a day). The months of February and March are the darkest, with less than a hundred hours of sunshine per month. In total, the sun shines on average 1843 hours per year.

Cyclones & storms

From April there is a chance of cyclones (hurricanes), tropical storms and depressions. On average, it hits a few times a year and Hong Kong is affected by a storm, which is often accompanied by heavy rainfall. The magnitude of the nuisance is mainly determined by the number of cyclones and the path they follow. Sometimes Hong Kong is almost completely hit, while at other times there is a distance of several hundred kilometers between the cyclone and the city, so that the misery is limited to (a lot of) rain and wind.


From March to August/September the humidity is relatively high. The wet season – in combination with the tropical temperatures – ensures that a fair amount of moisture remains in the air. Especially from ‘the peak’ you can see that well. With a relative humidity of 84%, May is the most humid month. After that, the humidity slowly decreases, to finally 69% in December.


The number of rainy days during this period is not only higher on average than in winter, the duration and intensity are also much higher. The chance of a shower in the summer is always quite high, and when it comes to your choice of clothing, you should definitely take that into account when traveling to Hong Kong. In total, there is almost 2400 millimeters of rainfall per year. This makes Hong Kong a relatively wet destination. Most precipitation falls in the period from April to October. At 444 millimeters (average), August is by far the wettest month.

Best time to visit Hong Kong

Do you want to know when is the best time to travel to Hong Kong? You can determine the best time to travel to a destination based on the weather and climate. In addition, there are other factors that are not directly related to the weather and that can influence the best travel periods for a travel destination. Think, for example, of holidays or festive periods, which makes traveling more interesting or not, because daily life comes to a standstill as a result. Hong Kong is a special destination within China. It is a so-called Special Administrative Region of the People’s Republic of China. That means that the same laws as in China itself should not apply until at least the year 2047. In this way, the capitalist system on which Hong Kong’s economy is based should be preserved. Hong Kong is a huge metropolis that is now home to more than seven million people. These inhabitants have to deal with a subtropical climate type that is known within the climate classification as a warm China climate (type Cwa). This climate type ensures mild winters and hot, wet and clammy summers within Hong Kong.

Best periods

Hong Kong has four seasons, of which early spring and late autumn can be referred to as the best travel time in our opinion. This is the period with pleasant temperatures, not too much precipitation and a reasonable amount of sunshine. With approximately 1800-1900 hours of sunshine per year, Hong Kong cannot be called sunny. When you talk about Hong Kong, you can say that it is a fairly wet destination. On an annual basis, there is an average of 2300 to 2500 millimeters of rain. That is more than three times the annual sum of Amsterdam. Because the amounts of rain and the number of rainy days are already starting to increase in April, we would rather choose Hong Kong as a travel month. November and December are sunnier and warmer than the spring months. Expect maximum temperatures of about 15 to 22 degrees Celsius and an average of six hours of sunshine per day. In November you can be unlucky that the rainy season lasts a little longer. December is an expensive travel period in the second half of the month, because there are more travelers because of the holidays.

The hurricane

Hong Kong is located in an area prone to severe storms and even hurricanes. They are called typhoons here. Hurricanes mainly occur during the hurricane season, which runs from June to November. Especially in the months of July and August it can be very bad weather with a lot of rainfall and very strong winds. Fortunately, hurricanes are quite predictable, which means that timely measures can be taken if necessary.
