Singapore faces deteriorating air quality in the coming period, according to latest forecasts tracking the Pollutant Standards Index (PSI). The index is now expected to remain solidly within the unhealthy category throughout the forecast window, marking a shift from previous predictions issued in early September.
Earlier forecasts from the start of the month had indicated air quality would fluctuate between moderate and moderate-to-unhealthy levels. The revised outlook suggests conditions will be more persistently poor than previously anticipated, warranting heightened attention from residents and authorities.
The sustained unhealthy air quality is likely linked to transboundary haze, a recurring phenomenon in the region during certain seasons. Such conditions typically prompt health advisories and may affect outdoor activities across the island state.
Residents are advised to monitor official air quality updates and take appropriate precautions during periods of unhealthy air, particularly vulnerable groups including children, the elderly, and those with respiratory conditions.
