When will air quality improve in Southeast Asia?
Singapore’s National Environment Agency has not set a date for conditions to improve, with dry conditions continuing over parts of southern ASEAN, keeping the risk of wildfires and transboundary haze elevated over the coming days. Meaningful regional improvement depends on the onset of the northeast monsoon season, expected in late October to November, which will bring more sustained rainfall across the region (1).
What is causing poor air quality in Southeast Asia?
Air quality across Southeast Asia is worsening due to Indonesia’s most intense wildfire season in 11 years, with forest and peatland fires burning across Sumatra and Kalimantan since early September. Prolonged dry conditions associated with strong El Niño conditions have increased wildfire risks, while prevailing winds carry smoke toward Singapore and Malaysia, worsening regional haze (2).
