Haze, heat and rain as they are today, from NEA's live feeds, and what the long-term dates on this site say about each. Updates every 5 minutes.
PSI is NEA's 24-hour Pollutant Standards Index: up to 50 good, 51–100 moderate, 101–200 unhealthy, 201–300 very unhealthy, above 300 hazardous. The forecast is PM2.5 from the Copernicus Atmosphere Monitoring Service (CAMS), via Open-Meteo, on a 40 km grid; treat it as a trend, not a reading. Haze has no long-term projection: the dry spells that favour it are on the method page.
Across Singapore, days with 50 mm or more of rain reach 1.5 times their 1995–2014 level by 2090 at today's pace of emissions. Where a street floods depends on drains and dips; each area page lists PUB's flood-prone sites.
