Air quality today

The air quality in Pasay is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 24.69 µg/m³ based on three valid observations reported through OpenAQ. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Pasay data set contains measurements for five pollutants – PM1, PM2.5, temperature, relative humidity and UM003 (particles per cubic centimetre). Six rows of sensor readings are available in total, but the coverage is uneven: all five variables appear at a single location on Pasay Rotonda, while PM2.5 is also reported from Santa Clara – Pasay City General Hospital, giving two distinct sites for that pollutant.

The most recent observation across the whole set is the PM2.5 value of 24.69 µg/m³ recorded at Santa Clara on 2026‑02‑10 22:06 UTC; all other pollutants were last updated on 2026‑01‑19 09:00 UTC, so they are about three weeks older. For PM2.5 the six available rows span a minimum of 6.76 µg/m³, a median of 16.23 µg/m³ and a maximum of 27.60 µg/m³, with the 10th‑percentile at 9.85 µg/m³ and the 90th‑percentile at 26.14 µg/m³, indicating a fairly wide spread in recent readings.

Temperature values from Pasay Rotonda range from 22.53 °C to 30.49 °C, with a median of 26.51 °C; the 10th‑percentile is 23.33 °C and the 90th‑percentile 29.69 °C, showing typical daytime variation. The single PM1 reading sits at 17.67 µg/m³, and relative humidity is recorded as a constant 48.51 % for the same timestamp, reflecting limited temporal depth for those metrics. UM003, measured in particles per cm³, is reported once at 959.64 particles/cm³.

Overall, the dataset offers recent PM2.5 data but older snapshots for the other four variables, and only one monitoring site supplies most of the measurements. Consequently, while the available numbers give a snapshot of conditions at Pasay Rotonda and Santa Clara, they do not capture the full spatial or temporal variability that may occur across the city.

Data notes

The data shown for Pasay is based on three valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T22:06:32+00:00 (Updated within 3 days). This snapshot reflects conditions at the time of sampling; however, air quality can differ across neighborhoods and change throughout the day, so values may vary from one location or moment to another.
