Air quality in Singapore showed a modest improvement overnight into Wednesday, although elevated PM2.5 readings were recorded in several regions as the haze lingers from nearby hotspots in Kalimantan and southern Sumatra.
- Slight air quality improvement seen early Wednesday
- Elevated PM2.5 levels in west, north and central Singapore at midday
- Health advisories urge vulnerable individuals to limit outdoor exposure
What happened
Singapore’s air quality improved slightly overnight into Wednesday, with the 24-hour PSI expected to range between 110 and 180, signifying generally unhealthy conditions in some regions. At midday, short-term PM2.5 levels were elevated particularly in the west, north, and central areas, fluctuating through the night with some dips into safer ranges. The east and south regions showed periods of moderate air quality, reflecting brief relief in those parts of the city.
These conditions are driven by transboundary smoke haze originating from hotspots in Kalimantan and southern Sumatra. While some areas experienced showers that may help reduce haze, dry conditions in key fire-prone regions mean the risk of severe haze persists. This ongoing situation continues to impact Singapore’s air quality, despite a brief improvement earlier in the week.
Why it feels good
The slight improvement in air quality, even if temporary, offers some reassurance to residents and vulnerable groups such as the elderly, pregnant women, and those with respiratory conditions. Achieving moderate air quality levels in parts of the city after days of unhealthy readings signals progress toward relief from persistent haze.
The availability of real-time data on PM2.5 and health advisories allows individuals to better manage their activities and protect their well-being. Authorities' clear guidance on mask usage and outdoor activity helps people make informed choices, fostering a sense of safety during these challenging environmental conditions.
What to enjoy or watch next
Residents are encouraged to stay updated on air quality changes throughout the week and heed health advisories—especially when PM2.5 levels rise into the high or very high bands. For those who do venture outdoors during elevated haze, wearing well-fitting N95 or equivalent masks provides effective protection against harmful particles.
As the haze situation depends on both local weather and developments in fire-prone regions nearby, watching for rainfall and changes in hotspot activity will be key indicators of future improvement. The community can also explore indoor activities and locations like Singapore's greenery spots on clearer days, to maintain wellness while protecting health.
