Chuncheon, November 10, 2026: daily mean PM2.5 11 µg/m³ (4 sensors), level “Moderate” — as in the Atmy Data Hub. Open methodology and data in JSON: Methodology and data sources · JSON

In Chuncheon the air is moderate right now (approximate, US EPA scale). From 18:00 to 04:00 local time the city mean PM2.5 rose from 12.3 to 21.7 µg/m³.

Light wind (0 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). Cold weather (3°C) possibly means more heating, a common source of particles.

Weather now: partly cloudy, 3°C, wind 0 m/s, humidity 99%. By 13:00 the wind is expected to pick up to 4 m/s, which may clear the air. By 18:00 the temperature will be about 11°C.
