NOTES:
  • Temperatures are degrees F, precipitation is inches of liquid. All normals are based on the period 1981-2010.
  • RH Year=Year of record high, RH Low=Year of record low. Temperature records for Charleston began in 1901.
  • HDD=Heating degree days, CDD=Cooling degree days
  • An asterisk (*) after the year of occurrence of record highs and lows indicates the record was reached more than once, with the indicated year being the most recent.
  • For some dates the degree days are shown by a pound sign (#). The symbol represents a value of less than one degree day, but more than zero degree days. It is used to smooth through aperiodic oscillations of zeroes and ones that are climatologically unreasonable. For example, if a station has 17, 15, and 18 normal heating degree days in June, July, and August, respectively, it is not possible to distribute the 15 July degree days evenly throughout the month using integer values (zeroes and ones) without creating unrealistic oscillations through the 3-month period. The use of fractional degree days (pound signs) does allow for a smooth transition from June through July to August.
  • Daily normal precipitation/snowfall values are more appropriate for calculating normals over a period of at least several days, rather than on a strict day-to-day basis.
  • Averages/totals may differ slightly from expected due to rounding.
