The haze situation in Singapore is expected to continue improving on Monday (2 November), with showers over Singapore, Indonesia’s Sumatra and Kalimantan, and surrounding areas.
The National Environment Agency forecasts that the 24-hour Pollutant Standards Index (PSI) will be between 51 and 80 on Monday, in the moderate range.
Showers are expected over parts of Sumatra, the Malay Peninsula, Borneo and Java in the coming days, potentially easing hotspot activity and haze. However, pollution levels may remain high in areas that have experienced prolonged dry weather, with a risk of transboundary haze.
Winds over the southern ASEAN region are expected to blow from the east or south-east, but the forecast showers are likely to ease the haze.
Showers fell over northern, western and eastern Singapore on Sunday (1 November). As of 6pm, one-hour PM2.5 concentrations across the island ranged from 13 to 33 micrograms per cubic metre, within the normal range. The 24-hour PSI was between 70 and 88, in the moderate range.
The agency said earlier that Singapore and the surrounding region were gradually entering the inter-monsoon period. Moderate to heavy showers are expected over parts of the island on most afternoons during the first two weeks of November. Haze conditions are expected to improve.
