September Weather Averages

Sorted by popularity:

What's the Weather like in Hong Kong in September


September marks the end of summer and the rainy season in Hong Kong.  Temperatures are still hot in the beginning of the month, but they'll cool down as September progresses into August.  The overall average monthly temperature is 27°C, a 2-degree drop from August.  Average daytime temperatures are 29°C and nighttime temperatures average 25°C.


As the rainy season wraps up in September, rainfall amounts drop significantly.  September rainfall totals in Hong Kong average 166mm, almost half that of August.  There are on average 14 days of rain in September. 

With that said, there is a high probability for Hong Kong to be affected by a tropical cyclone in September, with an occurrence of 1.5 typhoons in Hong Kong in September.  Rainfall amounts will dramatically increase and usually cause flooding.

Sunshine Hours

The days in Hong Kong average twelve hours long in September, with an average of six hours of sunshine every day.  Cloud cover really starts to decrease as the month goes on.  In the beginning of September there is a 75% chance of mostly cloudy to overcast skies, with that number falling to 56% by the end of September.


Don't think that the slight drop in temperatures in September will relieve you of the unbearable humidity from August.  The average relative humidity for the month does drop to 77%, but you'll be more comfortable at the end of the month.  The beginning of September can certainly feel like summer as far as temperatures and humidity are concerned.


Winds start to pick up in September, averaging 4.4m/s for the month but picking up to 5.0m/s by the end of the month.  In the beginning of September the winds will be a mix of southerly and easterly directions, with those easterly winds starting to settle in by the end of the month.

Dress Code

Because September can vary so much, be sure to check the fourteen-day forecast for a better idea of what you should pack.  Generally, for the whole month, you're best off packing for summer.  Consider loose, lightweight clothing to make the humidity more bearable.  Wear comfortable clothes when exploring the city and outskirts, and shorts & sandals are just fine for this.  You'll want to dress up more for going out to dinner or partaking in nightlife, so pants and a dress are a must.  A light raincoat isn't a bad idea either.
