Why live rankings? Smoke plumes are patchy and shift with the wind, so no direction is reliably cleaner. This list is recalculated from live PM2.5 every hour — and if everything nearby is smoky, it says so.

What this means · Stockton

Good

AQI 11

AQI = Air Quality Index

Typical person. Air quality is satisfactory for most outdoor plans.

Kids, seniors, heart or lung conditions. Unusually sensitive people can still enjoy the outdoors.

The AQI on this page follows fine particles (PM2.5). Particles here are 2 µg/m³ (Natural), so the headline and the particle scale below tell the same story.

Act two · Fine particles only

Where PM2.5 lands

This bar is smoke and fine particles (PM2.5) only. Left is cleaner air; right is heavier particle pollution. Today's particles sit in Natural.

2 µg/m³
Clean · 0Smoky · 40Severe · 80+

Act three · Particle ladder

What each PM2.5 rung feels like

  • 0–3µg/m³Natural. About as clean as outdoor air realistically gets.
  • 3–5µg/m³Clean. Crisp, destination-worthy air.
  • 5–9µg/m³Good. Clean city air; most people will not notice anything today.
  • 9–15µg/m³Elevated. Usually no big deal today; sensitive lungs may notice hard exercise.
  • 15–35µg/m³Polluted. Smoke or traffic pollution is now worth acting on.
  • 35–55µg/m³Unhealthy. Symptoms become more likely, especially with asthma or heart disease.
  • 55+µg/m³Severe. Everyone should reduce exposure and clean the indoor air.

Act four · Felt number

Cigarettes a week

A secondary feel for the particle load only — not a medical claim, and not a substitute for AQI.

0.6/wk

What is PM2.5?

Fine particles about 30× thinner than a human hair — small enough to slip through your lungs and into your bloodstream. We measure them inµg/m³: micrograms of particle mass in a cubic metre of air.

The math

PM2.5 here is 2 µg/m³.Berkeley Earth: 22 µg/m³ for 24 h ≈ 1 cigarette.A week at this level: 2/22 × 7 = 0.6 cigarettes.A long-term health-risk equivalence, not literal smoking.See how we work it out →
