Singaporeans can finally take a much-needed deep breath. After a grueling weekend that saw Singapore record the world’s worst air quality as the 24-hour Pollutant Standards Index (PSI) spiked to the highest levels, air quality across the island showed an improvement today. By noon on October 19, hourly PM2.5 readings had dropped back into the normal band across all five regions of the country—marking the first time since October 9 that multiple areas recorded moderate air quality. Here’s what we know about the Singapore haze situation.
Singapore’s air quality improves
This clean air is a big relief after a very smoky weekend, especially in the west. On Sunday morning, the West region hit a 24-hour PSI of 230—which was the highest number of the 2026 haze season. However, the air in the West got much better dropping to 115 by Monday. Similarly, the North dropped to a safe and moderate level of 85.
Although, the National Environment Agency (NEA) warns that the severe haze could continue for the rest of October. So, don’t pack away those N95 masks yet.
The prolonged dry weather continues to fuel widespread forest fires in Indonesia and prevailing winds blow the transboundary haze our direction. More to follow on the haze in Singapore.
