What's in Baker, Florida's Air?

The dominant pollutant in Baker, Florida is Ground-Level Ozone. Ground-level ozone forms when sunlight reacts with vehicle exhaust and industrial emissions. It is worst on hot, sunny, stagnant summer days. Ozone irritates the lungs, triggers asthma attacks, and reduces lung function — even healthy adults can feel chest tightness and shortness of breath after exercising in elevated ozone.

Is the Air Getting Better or Worse?

Air quality in Baker, Florida has been getting worse over the past decade, with median AQI climbing by roughly 1.4 points per year. That bucks the national trend of broad improvement, and most often reflects either growing wildfire smoke exposure (particularly across the West) or rising local emissions from population and freight growth.

In 2014, Baker, Florida posted a median AQI of 33. By 2023 that figure was 43 — a rise of 10 AQI points dirtier across 10 years of EPA records.

Health Context for Baker, Florida

Across the past five years, this area has logged just 2 days where AQI rose into the "Unhealthy for Sensitive Groups" range or worse — about 0 days per year, or roughly one every other month. That is a low count by national standards.

Healthy adults can continue normal outdoor activity in most weather, but should pay attention to AQI alerts during the worst pollution windows. People with asthma, heart disease, or pregnancy should reduce prolonged or intense outdoor exertion on flagged days, and consider running an indoor HEPA air cleaner during peak season. Because ozone peaks in the afternoon on hot sunny days, plan outdoor exercise for early morning or after sunset on bad-air days.

How This Grade Is Calculated

The AirHistory Air Quality Grade combines four signals: the 5-year median AQI (40% of the score), the 10-year trend direction (30%), the count of unhealthy days per year (20%), and the dominant pollutant type (10%). All four come directly from the EPA Air Quality System (AQS), which aggregates readings from federally certified monitors. Read the full methodology.

Baker, Florida has an Air Quality Grade of C (fair) with a 5-year median AQI of 40. The dominant pollutant is Ground-Level Ozone, and air quality has been worsening over the past decade.
