 Phoenix is experiencing generally good air quality today, continuing an improved trend seen throughout 2025. Most measurements taken this year have shown air quality index values well within the safe range, and the risk of health issues for the general public is low, though some individuals may experience effects from long-term exposure.

Analysis of air quality data for Phoenix in 2025 shows that 80 percent of the days have met the World Health Organization’s safe air quality limits. The average daily air quality index, or AQI, this year has been below 50, which is considered good according to federal standards. Air quality levels can fluctuate through the day; typically, the highest readings are seen in the early morning hours, ranging from AQI 51 to AQI 56. These levels may briefly reach moderate but generally return to good range during the afternoon and evening. The lowest AQI readings usually occur around 5 or 6 PM, registering values between 33 and 35, indicating periods of cleaner air.

Particle pollution, particularly PM10 and PM2.5, remains an ongoing concern for the Phoenix area. These fine particles become especially noticeable after events involving smoke, such as the heavy use of fireworks or stagnant air during winter weather. Moments of poor air quality, such as hazardous conditions seen at the start of the year due to fireworks, can pose health risks—especially to people with respiratory or heart conditions. Temporary symptoms may include coughing and nasal congestion, so experts recommend limiting outdoor activity when AQI readings rise and rinsing the nose after exposure.

Overall, air quality today is safe for most people, but residents with sensitivities should still monitor conditions as occasional spikes remain possible. Long-term effects of repeated exposure to fine particles are uncertain, especially for vulnerable groups, but Phoenix’s air has been cleaner in 2025 compared to previous years.
