Hey there! :D
Climates that are warm in the summer and cold in the winter are...
"B" Temperate
Temperate weather is very common, and it is easy to remember because it is like the in between of tropical and polar, and temperate means something average or mediocre. Tropical weather is hot and humid year round, and polar is cold and dry year round. Temperate weather has seasons that neither polar or tropical weather has. When you think of fall, winter, spring, summer... that kind of climate is temperate.
I hope this helps!
