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.
Daily normal precipitation 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.
