In Zenica the air is moderate right now (approximate, US EPA scale). From 10:00 to 23:00 local time the city mean PM2.5 fell from 37.2 to 20.0 µg/m³. The highest hour was 11:00 with 44.0 µg/m³.

Light wind (1 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). High humidity (86%) possibly makes optical sensors read somewhat higher.

Weather now: cloudy, 14°C, wind 1 m/s, humidity 86%. No major change in the wind is expected in the coming hours.
