Singapore continues to experience unhealthy air quality levels particularly in its western and central regions, with the Pollutant Standard Index (PSI) predicted to stay high on Wednesday due to haze drifting from nearby fires.
- PSI levels expected between 110 and 180 on Wednesday
- Haze from Kalimantan fires contributes to poor air quality
- Vulnerable groups advised to limit outdoor exposure and wear protective masks
What happened
At 11pm on Tuesday, Singapore's west and central regions recorded elevated one-hour PM2.5 particle concentrations, indicating unhealthy air quality. While the northern region stayed moderate, the east and south showed worsening conditions by midday, with the south improving briefly in the evening. The 24-hour PSI readings across the island ranged from 86 to 140, confirming the persistence of haze-related pollution.
The National Environment Agency has forecast that air quality will remain unhealthy on Wednesday, with PSI expected to be between 110 and 180. Despite rainfall over Singapore and its surroundings, smoke haze from ongoing fires in Kalimantan is expected to be carried over the island by prevailing southeast winds. Dry conditions in southern Kalimantan suggest that the smoke issue may continue in the near term.
Why it feels good
Although the current haze presents challenges, the brief improvement earlier in the week shows that air quality can fluctuate positively with changes in weather patterns. The showers observed help reduce some airborne particles, offering temporary relief to residents. Awareness and preparedness among the community have increased as advisory guidelines are clearly communicated, empowering individuals to take precautionary measures.
The coordinated efforts by authorities to monitor air pollutants and share real-time data contribute to public safety and health. Provision of reliable information through resources like the HazeMaskGoWhere website helps people access protective masks conveniently. This ongoing response encourages collective resilience and care during environmental episodes, reinforcing a healthier, more informed society.
What to enjoy or watch next
Residents are encouraged to watch hourly PM2.5 updates closely to assess immediate outdoor activity safety. Vulnerable groups such as the elderly, pregnant women, children, and those with heart or lung conditions should minimize prolonged outdoor exertion and consider wearing well-fitting N95 or equivalent masks when venturing out. Using these masks helps filter harmful fine particles and reduces health risks associated with haze exposure.
Looking forward, changes in weather such as potential rains can help improve conditions, so monitoring forecasts will be important. For those seeking relief from the haze, indoor activities and green spaces equipped with air purifiers provide a respite from the poor outdoor air. Authorities will continue to monitor the haze situation and update advisories as conditions evolve.
