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/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.
