Singapore's air quality showed signs of improvement as the 24-hour PSI reading fell to 100 at 11pm, down from 101 recorded an hour earlier. The modest decline signals a shift away from the higher pollution levels that had affected the region in the hours prior.
The return to moderate PSI levels brings relief to residents and businesses across central Singapore, though conditions remain elevated enough to warrant continued monitoring. The PSI scale classifies readings between 51 and 100 as moderate, a category that can affect individuals with respiratory conditions or heart disease.
The National Environment Agency continues tracking air quality metrics across multiple monitoring stations island-wide. Residents are advised to check real-time PSI updates and adjust outdoor activities accordingly, particularly those in vulnerable population groups including children, the elderly, and those with pre-existing health conditions.
Air quality fluctuations in Singapore are typically influenced by regional haze patterns, local emissions, and meteorological conditions. Authorities maintain contingency measures for potential further deterioration, though the latest readings suggest conditions are stabilising.
