Haze turns daily planning into an indoor-first decision
By OnTheRice · Sources and limitations · Report a correction
We see a continuing link between regional fires, wind direction and Singapore’s outdoor exposure. The important change is that earlier moderate readings have become unhealthy readings, while the source of smoke remains active.

Source confidenceHigh for official readings; moderate for our outlook
What’s changing?
OTR Database Data recorded a 24-hour PSI of 73–96 at 5pm on 4 October. NEA’s fresh 7 October update recorded PSI 105–140 at 6pm and 1-hour PM2.5 of 71–136 micrograms per cubic metre. Dry conditions and winds carrying smoke from Sumatra and Kalimantan connect the two snapshots. We therefore see a continuing planning risk over the next 24 hours. This is a comparison of reported ranges at different times, rather than a claim that every district worsened by the same amount.
Key points
- The fire-and-wind mechanism remains active.
- Use 1-hour PM2.5 for immediate activities and the 24-hour PSI forecast for next-day planning.
- We would prepare indoor alternatives for outdoor sessions and check NEA again before starting.
What could change this view?
- Rain, a change in wind direction or a sustained fall in local readings would weaken the view. Cloud cover also limits the satellite picture of hotspots. We do not infer a new hospital admission surge from air readings alone.
Bottom line
We expect outdoor planning to remain sensitive to haze over the next 24 hours. Prepare indoor alternatives and use the latest official readings.
Its source facts and prices still need independent checks.
