SINGAPORE: The Pollutant Standards Index (PSI) reading is in the moderate range at 59, as of 4pm on Tuesday.

In recent days, Singapore’s air quality has dipped, with the PSI slipping from good to moderate in parts of the island.

The National Environment Agency (NEA) said Singapore is currently in the Southwest Monsoon season, which typically lasts from June to September or early October.

It’s the traditional dry season for the southern ASEAN region.

NEA said an escalation of hotspot activities in Sumatra and Borneo can be expected during extended periods of dry weather.

And this can lead to transboundary smoke haze in the region.

The impact of the smoke haze on Singapore is dependent on factors such as the proximity and extent of the fires, the strength and direction of the prevailing winds, and the incidence and amount of rain.

The PSI reading is updated daily at 8am, noon and 4pm.
