Singapore's air quality expected to improve mid-week as haze eases

Singapore's air quality is poised to improve from October 9 onwards, according to the latest forecast from the National Environment Agency (NEA). The agency's projections indicate that the 24-hour Pollutant Standards Index (PSI) readings will transition from current levels toward the high moderate to mid-unhealthy range during the period.

The anticipated shift comes as wind patterns and atmospheric conditions are expected to affect the movement and dispersal of transboundary haze that has affected the island-state. The NEA has been closely monitoring air quality conditions and updating forecasts as new meteorological data becomes available.

Residents and outdoor enthusiasts are advised to continue monitoring official PSI readings from the NEA's website and mobile applications for real-time updates on air quality. The agency recommends that vulnerable groups, including the elderly, children, and those with respiratory conditions, remain cautious and limit outdoor activities during periods of elevated pollution levels.

The NEA regularly updates its air quality forecasts based on satellite imagery, ground-based monitoring stations, and regional weather patterns to provide Singaporeans with the most accurate and timely information available.
