Air quality today

The air quality in Accra is classified as USG today. The primary pollutant identified is PM2.5, with a measured concentration of 45.74 µg/m³ based on 33 valid observations reported through OpenAQ.

No other pollutants are listed for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Accra pulls measurements from 53 recorded rows representing 19 distinct monitoring sites across the Greater Accra Region. It currently includes readings for nitrogen dioxide (NO₂), particulate matter of three size fractions (PM₁, PM₂.₅ and PM₁₀), relative humidity, temperature, and particle count (UM003). The most recent observations were uploaded on 2026‑02‑10 22:00 UTC for PM₁, temperature, relative humidity, UM003 and the latest PM₂.₅ value was logged a few minutes later at 22:06 UTC the same day. In contrast, the PM₁₀ series is older, with its newest entry dated 2025‑01‑13 23:00 UTC, while NO₂ data are from 2023‑09‑15 23:05 UTC.

Across the available stations the measured values show a fairly wide spread. For PM₂.₅ the recorded range runs from a low of 7.55 µg/m³ up to 45.74 µg/m³, with a median near 14.8 µg/m³; PM₁ varies between 4.0 and 11.3 µg/m³ (median ≈ 8.6 µg/m³). Temperature readings span from just below ‑4 °C to 25.7 °C, centering around a median of 22.6 °C. Relative humidity stays between 63.6 % and 69.7 %, with most values clustered near 68–69 %. Particle concentration (UM003) ranges from roughly 440 to 2 370 particles per cm³, the middle 50 % lying between about 870 and 2 226 particles/cm³.

The coverage is uneven: while half of the pollutants have data refreshed within the past three days, PM₁₀ and NO₂ rely on older records, limiting insight into current conditions for those metrics. Consequently, city‑wide air quality snapshots may differ noticeably between well‑sampled parameters (PM₁, temperature, humidity) and those with sparse or dated observations.

Data notes

The data shown for Accra reflects 33 valid measurements and is marked as Updated within 3 days, with the most recent record logged at 2026‑02‑10T22:06:39+00:00. This snapshot provides a current view of city‑wide air quality but conditions can differ across neighborhoods and change throughout the day, so individual experiences may vary from the reported values.
