Warmest ZIP codes in South Carolina
Ranked by annual average temperature estimated from nearby weather observations.
How we rank average temperature
Average temperature is calculated from monthly mean temperatures at nearby weather stations. Each ZIP reflects nearby observations, with closer stations having more influence.
An annual average hides the season: a mild coastal ZIP and a hot inland one can share a value. Open a ZIP's profile for hot days, freeze days, and precipitation.
Only ZIPs with at least 1,000 residents are ranked, so a handful of households cannot top the list. 353 South Carolina ZIPs qualify.
