Singapore haze pushes air quality into unhealthy range

Original: singapore haze psi

Haze has returned to Singapore, with the Pollutant Standards Index showing air quality in the unhealthy range across most of the island. The National Environment Agency issued a haze situation update on 4 October, while CNA and The Straits Times report conditions dipped back into unhealthy territory overnight after a brief improvement. Residents are being urged to monitor readings and limit prolonged outdoor activity.

Why now: Deteriorating haze conditions are directly affecting daily life in Singapore right now.
