The climate of Hong Kong
Hong Kong has a warm sea climate (type Cwa according to the Köppen-Geiger climate classification). Many other sources describe this type of climate as a subtropical climate. The climate of Hong Kong is characterized by warm and relatively dry winters and tropically warm summers with both high precipitation figures and high humidity figures. The coldest month has an average 24 hour temperature below 18 degrees Celsius; this is why the climate cannot be referred to as tropical (type A-climate).


Temperature and sunshine
Hong Kong has an average maximum temperature of 25.6 degrees Celsius and an average minimum temperature of 21.1 degrees Celsius; recorded over the entire year. January is the coldest month with temperatures between 14.1 and 18.6 degrees Celsius on average. July is the warmest month with temperatures between 26.7 and 31.3 degrees Celsius on average. July is also the sunniest month with 214.9 hours of sunshine (more than 7 hours of sunshine per day). February and March are the darkest months with fewer than 100 hours of sunshine per month. Hong Kong gets 1,843 hours of sunshine per year.

Cyclones and storms
From April there is a risk of cyclones (hurricanes), tropical storms and depressions. Hong Kong gets hit by storms with heavy rainfall a few times per year on average. The inconvenience caused by these storms depends on the number of cyclones and the path they follow. Hong Kong may get hit fully by a cyclone one time while the next time a storm may pass at several hundreds of kilometers limiting the inconvenience to a lot of rain and wind.

Humidity figures
From March till August/September humidity figures are relatively high. This is caused by the wet season in combination with tropical temperatures. May is the muggiest month with a humidity figure of 84%. After this month humidity figures decrease to 69% in December.

During this period the number of rainy days is not only higher than during the winter; rainfall is much heavier and lasts longer as well. Chances of a shower during the summer are reasonably high. You should take this into account when packing for a trip to Hong Kong. Hong Kong gets almost 2,400 millimeters of rain per year; this makes Hong Kong a relatively wet destination. Most of the rain falls from April till October. August is the wettest month by far with 444 millimeters of rain.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month.
