Related factors (forecasted meteorological trends affecting PM2.5 levels): From 6–9 Jan 2026, ventilation is expected to be “good to mild,” with a closed atmosphere near the surface and strong winds on some days, so PM2.5 concentrations are expected to decrease. From 10–14 Jan 2026, ventilation is mostly “poor,” so PM2.5 levels are expected to start accumulating again. Today's forecast is cold mornings with strong winds and temperature drops of 1-3 degrees Celsius.
