What's the Weather like in Hong Kong in October

Temperature

Hong Kong experiences a nice cooling down in October.  If summer was too much for you, fall is a wonderful season in Hong Kong.  The average monthly temperature is 26°C, though the end of the month is much cooler.  Daytime temperatures start out at 30°C but cool off to 27°C by the end of the month.  Night temperatures average a pleasant 23°C.

Rain

October is considerably drier than the previous months.  On average it only rains for 8 days in October, yielding rainfall totals of only 41mm. 

Typhoon season is not quite over, however.  The mean occurrence of a tropical cyclone hitting Hong Kong in October is 0.9, so you can expect some kind of activity, much more so in the beginning of the month.  This is when the rains will fall, and expect winds to increase also.

Sunshine Hours

The days in Hong Kong last almost 12 hours in the beginning of the month and shorten to just over 11 hours at the end of the month.  Expect to see the sun for an average of six hours per day.  The chances of an overcast or mostly cloudy sky are 56% in the beginning of October, tapering off to 40% towards the end of the month.  Otherwise, the skies are mostly clear or partly cloudy.

Humidity

The average relative humidity drops to a tolerable 73% in October, helped out by decreasing rainfall and temperatures.  October will still feel humid, just not nearly as bad as the summer months.  Still, if you don't like humid conditions at all, you're best visiting Hong Kong in winter.
