Air quality in Saki right now
Right now the modelled US Air Quality Index for Saki, Oyo State, Nigeria is 144, which falls in the "Unhealthy for Sensitive Groups" band (up to 150). People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors.
The index is driven mainly by PM2.5, whose own sub-index is 144. 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 51 µg/m³, 3.4 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 92 µg/m³ against a guideline of 45; ozone is 47 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 8.7 µg/m³ (below the 24-hour guideline of 25).
Also this hour: desert dust at 79 µg/m³, high enough to haze the sky, carbon monoxide 333 µg/m³.

Every third hour of the CAMS forecast via Open-Meteo. US AQI uses rolling averages (24 h for particles, 8 h for ozone), so it moves more slowly than the hourly concentrations.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Saki, 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 51 µg/m³ in the next 24 hours while NASA satellites detected 6 fire hotspots within 300 km in the last day (nearest about 182 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 144, 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.
