National Environment Agency (NEA) climate data on monthly mean relative humidity recorded at the Changi Climate Station. The CSV series from 1982 through July 2023 supports heat-stress, building-energy, and epidemiology research in Singapore’s tropical environment. Monthly granularity captures monsoon and urban-climate variability better than annual summaries alone. NEA’s long-run station record underpins interoperability with other Changi meteorological datasets. The collection is a baseline open-data source for humidity trends at Singapore’s primary climate reference site.
