Air quality today

The air quality today in Singapore is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 7.76 µg/m³, based on 21 valid observations collected via OpenAQ.

Overall conditions meet the Good category criteria with no additional pollutants reported. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Singapore pulls in measurements from 36 recorded rows across 13 monitoring stations, covering six key variables: PM1, PM2.5, PM10, temperature, relative humidity and the particle count UM003. The most recent observations were all logged on 2026‑02‑10 (UTC) for five of the pollutants, with timestamps shown as 2026‑02‑10 23:00 UTC for PM2.5, temperature, PM1, relative humidity and UM003. PM10 is an outlier, its latest entry dating back to 2025‑01‑13 23:00 UTC, which means the information for that metric is over a year older than the rest.

Across the recent data, PM2.5 values range from about 2.8 µg/m³ at the 10th percentile up to 17.4 µg/m³ at the 90th percentile, with a median of 8.2 µg/m³; the extreme observed maximum is 21.0 µg/m³. Temperature spans from roughly 25.0 °C to 29.2 °C, centering around a median of 26.2 °C. PM1 shows a broader spread, with low‑end readings near 0.44 µg/m³ and high‑end values approaching 4.84 µg/m³ (median 2.89 µg/m³), while the recorded maximum reaches 5.39 µg/m³. Relative humidity varies between 58.9 % and 66.3 %, medianing at 62.9 %; UM003 particle concentrations range from about 271 particles/cm³ to over 1,006 particles/cm³ (median 681 particles/cm³), with the highest measured count of 1,116 particles/cm³.

The coverage is uneven: five pollutants have fresh, seven‑day‑old data, but PM10 relies on a single older record. Consequently, while recent snapshots give a clear picture for most variables, the older PM10 reading limits insight into current fine‑dust conditions. Users should keep in mind that measurements reflect specific stations and times, so city‑wide air quality can differ across neighborhoods and moments.

Data notes

The dataset comprises 21 valid measurements and is refreshed regularly, having been Updated within 3 days as of the latest pull on 2026‑02‑10T23:00:50+00:00. These values represent a citywide snapshot; actual air quality can differ across neighbourhoods and change throughout the day, so conditions at any specific location or moment may vary from what is shown here.
