Which state would have a warmer climate montana or florida why?

Florida has a warmer climate than Montana, as it is closer to the equator, near the tropical region.

Explanation:

Florida has a mostly humid subtropical climate, except for the southern part beyond Lake Okeechobee which has tropical climate. In the summer it is hot and the humidity is very high with temperatures steady at around 31–33°C during the day and around 23–27°C at night. During the summer, thunderstorms during the afternoons are very common, but the sun will usually return as soon as it disappears.

The hurricane season extends from June to the end of November. During these months, huge tropical storms can pull past Florida and the rainfall can be overwhelming along with the winds. In fact, the more pleasant weather is during the winter months from December to March when the temperature and humidity are slightly lower. Florida has more lightning strikes and thunderstorms than all other states in the United States; therefore, many think the "sunshine state" is an inappropriate name. However, Florida has about 3,000 hours of sunshine a year.
