why is it so foggy in la

Los Angeles is extra foggy right now because cool, moist ocean air is getting trapped near the surface while a warmer layer of air sits above it, plus recent and incoming storms are pumping extra moisture into the region. That combo makes thick marine-layer fog and low clouds much more common than usual, especially overnight and in the early morning.

Quick Scoop

• Moisture is way up
  Recent and forecast storms around New Year are bringing more humidity over Southern California than normal, loading the lower atmosphere with moisture that can condense into fog.

• Classic marine layer, but supercharged
  LA’s usual marine layer happens when cool ocean air flows inland under warmer air aloft, trapping low clouds and fog near the surface; a persistent high‑pressure pattern in recent months has helped keep that setup going longer and more often.

• Cool nights + calm winds = fog factory
  Overnight, the ground and air near the surface cool down, winds drop, and all that moisture condenses into fog, especially near the coast and basins where air can pool.

• Not smog, just actual fog
  People online have been mixing up “smog” and “fog,” but what most are seeing lately is natural marine-layer fog driven by weather patterns, not pollution spikes.

• Why it feels unusual now
  Local outlets note that the recent foggy mornings feel more like extended “May Gray/June Gloom” showing up in fall and winter, tied to a stubborn high‑pressure pattern and an active, wetter storm track starting 2026.
