Air quality today

The air quality today in Karachi Division is classified as Unhealthy. The primary pollutant identified is PM2.5. Measurements show a PM2.5 concentration of 121.5 µg/m³. These results are based on 75 valid measurements. The reported figure represents the average concentration derived from the set of valid observations. No PM10 data is available for this assessment. The measurement period includes multiple sampling points across the division. All values are expressed in micrograms per cubic meter. The assessment follows the Duck scoring methodology. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Karachi Division air‑quality feed draws from 25 monitoring stations and contains 137 individual rows of data. For most pollutants—PM2.5, PM1, temperature, relative humidity and particle count (UM003)—the dataset includes 24 to 28 recent rows, with the newest measurements recorded on 2026‑02‑10 22:00 UTC. Overall, 75 rows have been updated within the last 30 days, while 31 rows are classified as old and another 31 have an unknown timestamp. PM10 is the exception, with only four rows from two stations and no timestamp information, indicating very limited and outdated coverage for that metric.

Across the well‑covered pollutants the observed values show a broad spread. PM2.5 values range from a near‑zero 0.025 µg/m³ up to 121.52 µg/m³, with a median of 85.99 µg/m³ and the middle 80 % of readings falling between 15.06 and 98.94 µg/m³. PM1 varies from 0 to 76.24 µg/m³, median 32.65 µg/m³, with the 10th to 90th percentile bracket of 3.82–67.90 µg/m³. Temperature measurements span 19.63 °C to 36.69 °C, centering on a median of 26.02 °C, while relative humidity runs from 24.70 % to 62.01 % with a median of 47.93 %. The particle‑count metric (UM003) shows counts from 133.5 to 5 406 particles/cm³, median 2 257 particles/cm³, and a 10th‑90th percentile range of 459–4 734 particles/cm³. The sparse PM10 data, limited to a median of 44.59 µg/m³ and a range of 25.93–163.24 µg/m³, underscores the uneven sensor distribution. Because the dataset mixes recent, older and unknown‑age rows, conditions in Karachi can differ noticeably across neighborhoods and times, and the available numbers reflect that variability.
