Methodology & sources
Charleston
Temperature & precipitation — the official 1991–2020 climate normals from NOAA's U.S. Climate Normals, measured at Dwtn Charleston (NOAA GHCN station USW00013782), inside the city.
Cloud, humidity, wind & sunshine — modelled estimates from NASA POWER, NASA's satellite-and-reanalysis climatology. This is the standard global source for atmospheric variables, which are not measured at most weather stations.
Harare
Temperature & precipitation — 1991–2020 normals computed from 26 years of daily observations at Robert Gabriel Mugabe Intl / Harare, a weather station, about 12 km from the city centre. The underlying daily records come from NOAA's global station network.
