Air quality today
The air quality in Lagos is classified as USG today. The main pollutant identified is PM2.5, with a measured concentration of 54.0 µg/m³ based on one valid observation reported through OpenAQ.
No additional pollutants are noted for this assessment. 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 dataset for Lagos currently contains measurements from a single monitoring location – Lagos Old Town – and includes two pollutants: fine particulate matter (PM2.5) and temperature. Both variables are reported in the same row, with the most recent reading timestamped at 2023-10-16 22:00 UTC. Because this is the only station contributing data, the overall coverage across the city is very limited; there are no additional sites or recent updates beyond that date.
For PM2.5 the recorded value is exactly 6.651785771052043 µg/m³, which also serves as the minimum, median and maximum for this pollutant in the dataset. Likewise, temperature is reported at a single point of 23.57846721013387 °C, again representing the full statistical spread (min, median, max, 10th and 90th percentiles). With only one observation per pollutant, there is no variability to describe trends or differences across neighborhoods or times of day.
The freshness of the data is uniformly old: the latest timestamp for both PM2.5 and temperature dates back to mid‑October 2023, and there are no recent or unknown entries in the record. Consequently, while the figures give a snapshot of conditions at Lagos Old Town on that specific evening, they do not capture the broader temporal or spatial dynamics that can occur throughout the city. Users should keep in mind that actual air quality and temperature may differ markedly elsewhere in Lagos and at other times.
