概要

According to the latest air quality data, Phoenix's air quality on Saturday afternoon is registering at **57 AQI for PM2.5**, which falls into the **Moderate** category.[4] This reading indicates that air quality is acceptable, though some pollutants may pose a moderate health concern for people who are unusually sensitive to air pollution.[2]

Fine particulate matter, or PM2.5, remains the primary pollutant of concern in Phoenix.[3] These tiny particles in the air reduce visibility and can cause a hazy appearance when levels are elevated. The current moderate levels suggest residents should be aware of air quality conditions, particularly those with respiratory conditions like asthma or heart disease.

Looking at broader trends, Phoenix has experienced variable air quality throughout February 2026. Earlier in the month, the city saw AQI readings ranging from the low 40s to mid-60s, with some fluctuation depending on the time of day. The highest recorded AQI during daytime hours typically occurs around noon, when readings average around 64, while afternoon readings tend to improve to around 36 by 4 PM.[1]

For context on the year so far, approximately 60 percent of the 41 days measured in 2026 have maintained air quality within the World Health Organization's safe limits, while 40 percent have exceeded those thresholds.[1] This suggests Phoenix is experiencing relatively typical winter air quality patterns for the region.

Residents who are active outdoors or have respiratory conditions should consider limiting prolonged exertion during peak pollution hours, which typically occur in the late morning and early afternoon.[2] Those with respiratory disease such as asthma may want to monitor conditions closely and adjust outdoor activities accordingly.

The current moderate air quality is not expected to cause health effects for the general population, but maintaining awareness of PM2.5 levels remains prudent for sensitive groups and those planning extended outdoor activities.
