In Jastrzębie-Zdrój the air is good right now (approximate, US EPA scale). From 16:00 to 03:00 local time the city mean PM2.5 rose from 5.8 to 10.3 µg/m³. The highest hour was 20:00 with 24.7 µg/m³.
Light wind (2 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: clear, 6°C, wind 2 m/s, humidity 86%. No major change in the wind is expected in the coming hours. By 16:00 the temperature will be about 14°C.

Fresh data for Jastrzębie-Zdrój are insufficient (last update: 04:00 local time, 02:00 UTC). Open the map for the latest readings of individual sensors.
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.
Over the last 108 days with data, the mean daily PM2.5 in Jastrzębie-Zdrój was 8.1 µg/m³ — 1.6 times the WHO annual guideline (5 µg/m³). Over the last 30 days: — µg/m³. From Atmy's archive of daily city means.
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.
