National Environment Agency (NEA) reports the monthly number of rain days at the Changi Climate Station in Singapore, counting days with at least 0.2 mm of rainfall. The CSV from 1982 through July 2023 supports climate variability and urban drainage studies. Researchers can relate rain-day counts to monsoon seasons and long-term wet-day trends. Monthly updates extend Singapore’s official rainfall climatology.
