National Environment Agency (NEA) climate open data publishes monthly absolute extreme minimum relative humidity recorded at Changi Climate Station. The Relative Humidity - Absolute Monthly Extreme Minimum CSV extends from 1982 through the catalogued end for long-run humidity analysis in Singapore’s tropical environment. Building scientists and epidemiology researchers can examine dry spells that affect comfort, mould risk, and outdoor activity. The series complements other NEA temperature and rainfall extreme-value collections.
