 Phoenix is experiencing good air quality today, November 24, 2025, with an Air Quality Index near 37, categorized as good and well within both U.S. EPA and World Health Organization safety limits. Over 80 percent of days this year in Phoenix have stayed within health-based guidelines, indicating significant air quality progress compared with previous years.

Throughout the last 24 hours, the Air Quality Index in Phoenix peaked at 62 overnight and dropped to a low of 25 late in the afternoon. These fluctuations are normal, with air quality often best during daylight hours and slightly worse in the early morning, likely due to weather conditions and traffic patterns. Even at today’s daily peak, the air has remained in the healthy range for the general public.

The dominant pollutant registered today is fine particulate matter, labeled PM2.5, which can be produced by vehicle emissions, construction dust, and natural sources like windblown soil. Periods of cloud cover and light wind, both of which are present today along with mild temperatures, often help keep air pollutants from building up, contributing to the favorable air quality currently observed.

Despite this favorable trend, Phoenix continues to face long-term challenges from pollutants such as ozone and dust. While particle pollution has been on a downward trend, the city still ranks high nationally for the number of unhealthy ozone days over the span of a year. Ozone is most likely to rise in the hot, sunny months or during periods with stagnant, still air, but cooler November conditions tend to suppress these levels.

For those with existing respiratory or heart conditions, simply paying attention to daily updates is advised, though risk from today’s air is rated low for everyone. Continued improvement in air quality can be aided by reducing vehicle idling, maintaining engine performance, and making thoughtful landscaping choices that cut back on emissions-producing vegetation.

Overall, today’s air is clean and safe, but Phoenix’s fast growth and regional climate require ongoing vigilance for future air quality management and public health protection.
