It should be
thirty-six point five degrees Celsius.
The hyphen is used in all two-word numbers from twenty-one through ninety-nine.
The normal temperature of the human body is 36.5C.
============
1. thirty two degrees point Celsius
2. thirty-two degrees point Celsius

The hyphen is used correctly in "thirty-two". One would write out 126 as "one hundred twenty-six", etc.
One would not usually write out the temperature, though. And "thirty-two degrees point..." makes no sense. It's "32 degrees Celsius". The word "point" is only used to indicate a decimal. Point what?
If you begin a sentence with the number, you should write it out: "Thirty-six point five Celsius is the normal temperature of the human body." Inside the sentence, we use the numerals 36.5.
