If you opened your phone\u2019s weather <\/a>app to an air quality alert this morning in Austin<\/a>, you\u2019re not alone\u00a0\u2014 apps like the Apple Weather app, AccuWeather and IQAir have deemed the air quality <\/a>\u201cunhealthy for sensitive groups\u201d Thursday.<\/p>\n

Here\u2019s what you need to know about the air quality in Austin on Thursday and what exactly makes it unhealthy.<\/p>\n

The short answer: pollution.<\/p>\n

According to AirNow<\/a>, a government website sharing air quality data, air quality is essentially graded on an index from zero to 300+, the Environmental Protection Agency\u2019s Air Quality Index (AQI). The numbers are calculated by the concentration of five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide and nitrogen dioxide. The numbers coincide with categories: good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy and hazardous. The most extreme category\u00a0\u2014 hazards\u00a0\u2014 indicates emergency conditions, while the least extreme\u00a0\u2014 good\u00a0\u2014 indicates that air pollution poses little or no risk to the public.<\/p>\n

Thursday\u2019s AQI is well over 100, according to multiple weather sources, meaning it\u2019s unhealthy for sensitive groups and experts are encouraging folks to stay indoors as much as possible.<\/p>\n

AccuWeather <\/a>cites PM2.5 as \u201cfine particulate matter,\u201d meaning small pollutant particles with a diameter less than 2.5 micrometers. These particles can be inhaled and enter the lungs and bloodstream.<\/p>\n

\u201cThe most severe impacts are on the lungs and heart,\u201d the AccuWeather website reads. \u201cExposure can result in coughing or difficulty breathing, aggravated asthma, and the development of chronic respiratory disease.\u201d<\/p>\n

According to experts at McGill University<\/a> in Canada, PM2.5 is the type of air pollution that kills the most people worldwide. Experts have called for worldwide air quality standards to prevent what they say are \u201cpreventable\u201d deaths from inhaling PM2.5 particles.<\/p>\n

According to the American Lung Association,<\/a> Austin is high-risk for ozone pollution. A 2025 study gave Travis County a failing grade for the number of high ozone days, as well as for average annual particle pollution. The study gave Travis County a \u201cB\u201d grade for 24-hour particle pollution, meaning the area averaged fewer unhealthy air days due to PM2.5 particles. But the bad days outweighed the good ones, earning Travis County an \u201cF\u201d overall for annual particle pollution. The American Lung Association notes that its\u00a0methodology differs\u00a0from the EPA\u2019s AQI.<\/p>\n
