Air quality in three regions of Singapore improved from the unhealthy range to the moderate range on Saturday, according to the National Environment Agency.
Singapore's central, west, and east regions recorded 24-hour Pollutant Standards Index (PSI) readings in the moderate range by midnight on Sunday, following earlier unhealthy levels. The central region's PSI dropped to 91 from a peak of 123 at 1am on Saturday. The west and east regions also returned to the moderate range, with readings of 86 and 77 respectively at 12am. As of 7am on Sunday, all five regions in Singapore remained in the moderate range.
The north and south regions remained in the moderate range throughout the day, with PSI readings of 75 and 72 respectively as of 12am. The 24-hour PSI entered the unhealthy band of 101 to 200 at 7am on Friday, marking the first time the PSI had exceeded 100 since October 8, 2023. This prompted the National Environment Agency (NEA) to start issuing daily haze advisories, including a 24-hour PSI forecast, to help the public plan activities and events for the following day.
Why it matters
The improvement in air quality affects public health and daily activities in Singapore, particularly for those sensitive to air pollution.
