In Oviedo City the air is good 🟢 AQI 46. Higher than three hours ago. 🌧️ +13 °C · Precipitation 0.1 mm · Wind 1 m/s
In Oviedo City the air is good right now (approximate, US EPA scale). From 10:00 to 23:00 local time the city mean PM2.5 rose from 4.6 to 8.3 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: rain, 13°C, wind 1 m/s, humidity 94%. No major change in the wind is expected in the coming hours.

Right now in Oviedo City, PM2.5 averages 8.3 µg/m³ — “good” on the US EPA scale (approximate, from hourly readings). Mean of 4 sensors from Sensor.Community, Government stations, readings from 21:00–22:57 local time (20:00–21:57 UTC), summary prepared at 23:00 local time. Median: 9.1 µg/m³; range across sensors: 4.8–10.2 µg/m³.
The current level is “good” (US EPA scale, approximate). Air quality is satisfactory; no restrictions are recommended. This is the standard guidance of the scale, not medical advice.
Highest current reading: 10.2 µg/m³ (SC #56698). Lowest: 4.8 µg/m³ (SC #89530). 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.
