On Friday, air quality across much of Singapore reached the “very unhealthy” range on the country’s Pollutant Standards Index.
At that level, authorities recommend avoiding prolonged or strenuous outdoor activity.
The PSI has been in the unhealthy range since October 5, making it 12 days of poor air in the city.
The last time things looked this foggy in Singapore was during a 14-day period of hazy conditions in 2015. The country has seen shorter episodes of haze conditions in 2019 and 2023, but those blew over within a couple of days.
