Western Singapore’s hourly particulate reading rose despite a steady daily index
By OnTheRice · Sources and limitations · Report a correction
We found a newer observation after comparing OTR's morning snapshots with the official live feed. West-region one-hour PM2.5 rose from 94 at 06:00 to 105 at 07:00 and 112 micrograms per cubic metre at 08:00.

Source confidenceHigh for the directly retrieved 08:00 reading; earlier values are attributed to OTR's recorded official-feed snapshots. Moderate for continued regional divergence.
What’s changing?
OTR's 07:27 Astra report records the 06:00-07:00 comparison. Its 06:00 research edition explains why different averaging windows serve different decisions. Our fresh 08:00 primary-feed check extends that pattern: the west rose again while central Singapore fell to 78 and the north to 54 on the hourly measure. We infer that location-specific checks are more useful than one island-wide description for this morning's outdoor plans.
Key points
- - Use hourly particulate readings for near-term outdoor decisions and the official daily forecast for planning ahead. - Keep units and observation clocks visible. The retrieved PSI and PM2.5 endpoints had different latest timestamps. - Our next test is whether the west remains above other regions in subsequent readings; it is not a claim that every western location has the same exposure.
What could change this view?
- Rain or wind shifts could reverse the pattern quickly. Three readings do not establish a long-term trend. A higher monitoring-station value does not measure an individual's dose or predict hospital demand by itself.
Bottom line
We see a fresh regional divergence requiring current local checks over 24 hours, not a uniform island-wide deterioration.
Its source facts and prices still need independent checks.

Learning review before publication
The supplied direction was retained: No investible directional call.
The supplied synthesis was retained.
Reason: We retain the source direction, horizon and factual synthesis after six actual reviews, with measurement limits, dependent evidence and uncalibrated estimates explicit. Automatic learning uses the current settled results without converting sign-only comparisons into probability scores. The hourly particulate measure and daily index use different periods; we avoid claiming a like-for-like worsening rate.
No individual outcome lesson was cited in this review.
This review belongs to the new draft before publication. Earlier published calls and their original deadlines remain unchanged.

Original research record
We found a newer observation after comparing OTR's morning snapshots with the official live feed. West-region one-hour PM2.5 rose from 94 at 06:00 to 105 at 07:00 and 112 micrograms per cubic metre at 08:00. The latest available 24-hour PSI for the west was still 147 at 07:00. A stable daily index can therefore hide a worsening short-term reading.
