Foggy Skies: Fog or Haze? Humidity Holds the Clue.

During autumn and winter, hazy skies are common. Is it fog or PM2.5 haze? Humidity offers a simple way to tell the difference. Fog typically dissipates as the sun rises and temperatures increase. Haze, however, consists of tiny particulate matter (PM2.5) that persists even after sunrise, continuing to impact our health.

While distinguishing between fog and haze can be tricky on dewy mornings, if the haze remains after 8 am, it’s a warning sign of PM2.5 air pollution. These tiny particles penetrate the respiratory system, causing serious long-term health problems, particularly for children and the elderly. Always wear a PM2.5-rated mask when venturing outdoors.
