Can the weather be cold?

Sure, it's cool. Language was originally used to describe our feelings. People are somatosensory, and some days will make you feel comfortable, clear and cool, which means cool. If you have this question, I suggest you simply sort out all the words describing the weather at once, such as sultry, humid, refreshing, dry, humid and so on. This can be extrapolated, and the efficiency will be very high. Hope to adopt, thank you.
