The National Environment Agency (NEA) is Singapore’s public agency for environmental information and services. Its Haze website helps the public monitor air quality and understand regional haze conditions through regularly updated readings, maps, forecasts, and health guidance. Visitors can check the 24-hour Pollutant Standards Index (PSI), one-hour PM2.5 readings, and pollutant sub-indices, with air-quality information presented for Singapore’s North, South, East, West, and Central regions. The site also explains air-quality bands and descriptors, and displays hotspot information derived from satellite data, with cautions about limitations caused by cloud cover and satellite coverage.

NEA provides updates on weather, smoke haze, hotspots, and outlooks for the southern and northern ASEAN regions, including information on prevailing winds and the potential for transboundary haze. The website offers health advisories, downloadable materials such as posters and a PDF advisory, and links to related haze resources. Users can also access NEA’s news, contact and feedback channels, social media, and mobile apps.
