Air quality in Bida right now
Right now the modelled US Air Quality Index for Bida, Niger State, Nigeria is 166, which falls in the "Unhealthy" band (up to 200). Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed.
The index is driven mainly by PM2.5, whose own sub-index is 166. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 52 µg/m³, 3.5 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 89 µg/m³ against a guideline of 45; ozone is 71 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 4.7 µg/m³ (below the 24-hour guideline of 25).
Also this hour: desert dust at 71 µg/m³, high enough to haze the sky, carbon monoxide 540 µg/m³.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Bida, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.
Wildfire smoke
PM2.5 is forecast to reach 102 µg/m³ in the next 24 hours while NASA satellites detected 96 fire hotspots within 300 km in the last day (nearest about 57 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
Advice for sensitive groups
At 166, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
