There are some climates that are classified as Csa, but the winters a bit too cold to be truly considered as Csa, and then there are some climates that are a bit to wet in the winter to be considered Bsk.
So here some typical Csa climates:
Malta
Los Angeles
Perth
Now these are the Csa climates that are a bit too cold (similar to how NYC is too cold to be Cfa, even if it technically is)
Walla Walla
Medford
Tashkent
Yreka
And then there are some Bsk climates that are way to wet in the colder half of the year.
Tehran
Zanjan
And this is what I think of when I think Bsk.
Yakima
And then this is your typical Dsa climate.
Bishkek
Considering how rare Dsa climates are, should those Climates be instead classified as Dsa?
