 Phoenix's air quality today stands at an **unhealthy** level of 158 AQI, primarily driven by **PM2.5** particles, according to real-time data from AirNow.[5] This rating means sensitive groups like children, the elderly, and those with asthma or respiratory issues may feel immediate effects such as breathing difficulties or throat irritation, while healthy people could experience symptoms with extended exposure.[2][3]

High **nitrogen dioxide (NO2)** levels contribute to the poor conditions, raising risks of coughing, respiratory infections, and aggravated asthma with prolonged exposure.[2] Forecasts from AccuWeather predict the **unhealthy** status persisting through Monday, December 22, with Tuesday shifting to **poor**—advising reduced outdoor time for all.[2]

Recent trends reveal fluctuations: In the last 24 hours, Phoenix hit a peak of 88 AQI at 3 AM (nighttime high average 74) and dipped to 40 at 3 PM (daytime low average 39).[1] Over 2025, 73% of days stayed within WHO safe limits, but winter inversions trap pollutants in the Valley, worsening quality.[1] Daytime peaks often occur 7 AM to noon (average 59), easing by evening.[1]

Despite Arizona's sunny reputation, seasonal factors like stagnant air and distant wildfires amplify risks. Vulnerable residents should limit exertion outdoors, use indoor air purifiers, and monitor updates from the Arizona Department of Environmental Quality. Staying informed helps safeguard health amid these hazy skies.[3]
