Why only "sunshine" is placed after "amount of"? In what kind of situation should I put an "amount of"?

"Amount(s) of" is used to describe a unit that can be measured, and sunshine can be measured in terms of hours. For example, two hours of sunshine in a day. Technically, rainfall can also be measured in units, so "amounts of rainfall" can be used in this sentence too. In reference to "temperatures," we cannot use "amounts of" as the unit is already implied (degrees), so "amounts" is not necessary here. Ex: We will have an average amount of rainfall this year. Ex: California is experiencing a very above average number of forest fires this year.
