Haze conditions in Singapore fluctuate across regions, with several outlets reporting improvements at times while others describe continued unhealthy or even very unhealthy air quality in certain areas. Early readings cited in one report show PM2.5 levels returning to a “normal” range overnight, while other coverage highlights PM2.5 remaining elevated and PSI falling into moderate to unhealthy bands in the west and central parts.
Channel NewsAsia repeatedly ties the day-to-day variation to National Environment Agency forecasts, including expectations for the 24-hour PSI to stay elevated or unhealthy on specific days and suggestions that haze may ease with forthcoming showers. The Straits Times focuses more on the distribution of PM2.5 and PSI bands across regions—such as periods when some areas improve to moderate levels while others still record elevated PM2.5 or unhealthy PSI. Another CNA report emphasises the impact of haze on daily routines and notes that the west has seen some of the highest readings, with conditions remaining dynamic.
Across reports, the shared theme is spatial variation: the west often shows the highest PSI readings, while other regions move between elevated, unhealthy, and comparatively better ranges as weather and haze levels change.
