In Valjevo the air is unhealthy 🔴 AQI 160. About the same as three hours ago. ☁️ +14 °C · No precipitation · Wind 1 m/s
In Valjevo the air is unhealthy right now (approximate, US EPA scale). From 10:00 to 23:00 local time the city mean PM2.5 rose from 31.5 to 68.5 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 (94%) possibly makes optical sensors read somewhat higher.
Weather now: cloudy, 14°C, wind 1 m/s, humidity 94%. No major change in the wind is expected in the coming hours. By 10:00 the temperature will be about 20°C.

Daily mean PM2.5 on November 10, 2026 (00:00–24:00 UTC = 01:00–01:00 UTC+1): 58 µg/m³ from 4 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 1 of 19 cities in Serbia and No. 25 of 676 worldwide, from the most polluted.
Right now in Valjevo, PM2.5 averages 68.5 µg/m³ — “unhealthy” on the US EPA scale (approximate, from hourly readings). Mean of 4 sensors from Government stations, Sensor.Community, readings from 22:00–22:56 local time (21:00–21:56 UTC), summary prepared at 23:00 local time. Median: 69.7 µg/m³; range across sensors: 23.0–111.5 µg/m³.
The current level is “unhealthy” (US EPA scale, approximate). Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it. This is the standard guidance of the scale, not medical advice.
Highest current reading: 111.5 µg/m³ (SC #89937). Lowest: 23.0 µg/m³ (Beograd Lazarevac (Gradski zavod za javno zdravlje Beograd)). The list shows every sensor, highest first.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
