Haze in Singapore: Air quality improves with 3 of 5 regions recording moderate PSI levels
However, PM2.5 levels were in elevated in 4 of the 5 regions.
Singapore experienced a break in the haze on Oct 20, 2020, as air quality improved across the island. Early in the morning, PSI readings across most regions stood in the moderate range, typically between 51 and 100. However, the west and central regions saw unhealthy levels, indicating PSI values above 101. According to the National Environment Agency (NEA), the haze situation had improved since the previous day, Oct 19, when only three out of the five regions recorded moderate air quality.
This marked a significant improvement from last week, when PSI readings often hovered in the unhealthy or very unhealthy bands. The hourly PM2.5 levels, a measure of fine particle pollution, also fluctuated, with some areas experiencing elevated concentrations. Forecasters predicted that smoke haze from nearby Indonesia could return, potentially affecting air quality in the days ahead as winds shifted.
