Miami air quality today

Outdoor activity is generally possible, but conditions are not ideal.

Data: Current Open-Meteo model estimate

Practical guidance

Outdoor

Outdoor activity is generally possible, but conditions are not ideal.

Why: AQI or pollutant levels are elevated, so this guidance is more cautious.

Running

Outdoor running is generally fine, but air quality and warm, humid conditions may make harder efforts feel heavier.

Why: Air quality indicators are elevated, so the running guidance is more cautious.

Ventilation

Ventilate briefly and check conditions again later.

Why: AQI or pollutant levels are elevated, so longer ventilation may be better later.

What affects air quality in Miami

Miami-Dade County identifies older diesel engines used at its ports as a local source of air pollution.

This is county port context, not a statement about current conditions, every neighborhood or all of Miami.

Local monitoring and context

Miami-Dade's official network uses different sites for different pollutants: Kendall measures PM2.5, while Miami Fire Station #5 and Witkop Park measure PM2.5 and PM10.

Station-specific pollutant coverage does not mean that one monitor represents every neighborhood or the whole city.

Miami-Dade County Air Monitoring View original source

Miami-Dade County says its air-quality work includes monitoring air pollution, enforcing air-pollution laws and issuing permits.

This describes the county authority's program, not the provenance of the current data shown on this page.

City air quality FAQ

How should I read the AQI for Miami?

US AQI condenses air quality into one value. On this page, it helps you quickly judge whether conditions look good, moderate or more polluted than usual.

Is the air quality good for going outside?

Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.

Should I ventilate right now?

The ventilation card considers AQI and pollutants such as particles, nitrogen dioxide and ozone. If values are elevated, a shorter opening or a later moment may be better.

Why can air quality change during the day?

Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.

Sources and methodology

Current data

This page uses US AQI.

Current and hourly air-quality values are CAMS-based model estimates, not measurements from a local monitoring station. They may not reflect street-level conditions.
