It sometimes goes down as far as 5C (41F) for
a few days in the winter, but believe it or not,
temperatures do vary within this tiny territory,
it being colder, generally, in the northern New
Territories towards the mainland border.
That being said, 5C feels a lot colder here
than in nominally colder climes, because few
homes have proper heating, so Hongkongers
freeze indoors with the Hg below 10C (50F)
in the winter, while folks in London or NYC
stay toasty warm in their heated bedrooms.
