The event brings hazy skies, reduced air quality, and higher thermal sensation (heat index) with moderate concentrations expected nationwide except for lower levels in the west. Atmospheric Effects: Widespread hazy or misty skies and an increased heat index / thermal sensation. Why this Matters for YouSaharan dust causes reduced visibility, hazy skies, and a noticeably higher heat sensation due to the warm, dry air mass it carries. Sunrise and sunset photography may actually benefit from the dust, which can produce vivid orange hues. The dust concentration is moderate and not considered dangerous for healthy individuals.
