Annual Temperature Range Formula

The following equation is used to calculate the Annual Temperature Range.

AT = MaxT - MinT
  • Where AT is the annual temperature range
  • MaxT is the maximum monthly average temperature for the year
  • MinT is the minimum monthly average temperature for the year

To calculate the annual temperature range, subtract the minimum average temperature for the year by the maximum average temperature for the same year.
