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 · Greater Sudbury

Low risk

AQHI 1

AQHI = Air Quality Health Index

Typical person. Ideal air for usual outdoor plans.

Kids, seniors, heart or lung conditions. People with heart or lung conditions can usually keep their normal outdoor routine.

Particles here are 1 µg/m³ (Natural).

Act two · Fine particles only

Where PM2.5 lands

This bar is smoke and fine particles (PM2.5) only — not the full AQHI mix. Left is cleaner air; right is heavier particle pollution. Today's particles sit in Natural.

1 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 AQHI.

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.
