このコンテンツについて
The moderate air quality classification means that while the air is generally acceptable, certain groups should exercise caution. Active children and adults, as well as individuals with respiratory conditions like asthma, should limit prolonged outdoor exertion today. The primary air pollutants contributing to Phoenix's current conditions include particulate matter, with PM2.5 levels at 19 micrograms per cubic meter and PM10 at 52 micrograms per cubic meter.
This moderate reading represents a relatively typical day for Phoenix during late autumn. The city's air quality has shown improvement this year compared to previous years, with 2025 ranking as one of the better years in the past five years. According to recent data analysis, approximately 80 percent of days in 2025 have remained within the World Health Organization's safe air quality limits, indicating an overall low health risk level for the population.
Phoenix's air quality typically fluctuates throughout the day, with the worst conditions generally occurring during early morning hours between midnight and 3 a.m., when AQI readings average around 56. The best air quality usually occurs during afternoon hours, particularly around 5 p.m., when readings drop to approximately 35.
While today's moderate air quality poses little concern for most residents, those with respiratory sensitivities may want to monitor conditions closely. The light winds and relatively mild temperatures create stable atmospheric conditions that allow pollutants to accumulate somewhat, contributing to the moderate classification. As evening approaches, air quality is expected to improve slightly as temperatures cool and atmospheric mixing occurs.
For most Phoenix residents, today presents suitable conditions for outdoor activities, though individuals with respiratory conditions should remain mindful of current air quality levels when planning extended outdoor time.
