A moderate climate is the
best, whether if it would be
moderately cold or
moderately hot. As a
person who likes the cold
as my favourite season.
But if we're talking about
extreme situations, I might
go with cold because let's
compare two cities hot
Arizona to cold Montana.
In Montana, there are
around 40 days of below
freezing weather with some
snowing. There are also
four distinct seasons
including warm summers.
So it accommodates both
cold and warm weather.
In Arizona, there are
around 110 days of triple
digit heat. No fall, and it
can still be hot in Octobers.
So, I would prefer a cold
climate region over a hot
climate region.
