The air quality in Miami-Dade usually falls in the "Good" range throughout the year.  However, there are a couple of times throughout the year when the Air Quality Index (AQI) falls to below the good range, which may be harmful to certain sensitive groups such as the elderly, the young and those with respiratory conditions.

Miami-Dade County offers an Air Quality Notification Service that you can customize for your own needs, allowing you to protect the health of yourself and your family. 

Air Quality Standards and Trends

The purpose of the Air Quality Index is to help you understand what local air quality means to your health. To make the AQI as easy to understand as possible, the U.S. Environmental Protection Agency (EPA) has divided the AQI scale into six categories.

Each category corresponds to a different level of health concern.
