The air quality in Calabar today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
A single valid measurement recorded a PM2.5 concentration of 6.8 µg/m³, and no PM10 value is available for this assessment. Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Calabar air‑quality record contains four sensor readings covering four pollutants: PM1, PM10, PM2.5 and temperature. All four measurements come from a single monitoring location, so the dataset reflects conditions at one spot rather than citywide coverage.
Each pollutant shows a single reported value because only one row is available for each. The median, minimum and maximum are identical, indicating no observed variation in the limited sample. PM1 registers 6.04 µg/m³, PM10 10.54 µg/m³ and PM2.5 6.8 µg/m³. Temperature is recorded as –2.01 °C. Because there is only one observation per pollutant, the inter‑percentile range (10th–90th) collapses to the same figure.
The timestamps reveal a mixed picture of data freshness. The PM1, PM10 and temperature readings were last updated on 2024‑04‑24 at 00:27 UTC, which is more than a year old. In contrast, the PM2.5 value was refreshed more recently on 2026‑02‑09 at 22:58 UTC, falling within the “updated within seven days” freshness category. Overall, three of the four rows are classified as old data, while only one row meets a recent update standard.
Given the limited number of stations and the age of most measurements, the available figures provide only a snapshot of conditions at a single point in time. Conditions across Calabar can differ by neighbourhood and over shorter periods than those captured here, so users should treat these numbers as indicative rather than comprehensive.
