SINGAPORE - The air quality in northern Singapore has dipped to a 'moderate quality' as of 4pm today, the National Environment Agency (NEA) reported.
The Pollutant Standards Index (PSI) reading in the north was 53, while the rest of Singapore experienced fairly good air quality ranging from PSI 33 to 41.
NEA attributed the hazy conditions to the current Southwest Monsoon season, which sees winds blowing predominantly from the southeast or southwest.
Smoke from hotspot activities in Sumatra and Borneo, where weather is dry, may result in transboundary smoke haze in the region.
Singapore is expected to experience brief periods of slightly hazy conditions over the next few weeks should fires in the region persist.
NEA advised those who suffer from heart or lung disease, children and the elderly to reduce prolonged or heavy outdoor exertion if they live in the North.
