Today's air quality in Phoenix shows moderate pollution levels with a mixed forecast. As of this morning, Phoenix has a PM10 rating of 69 AQI with a 24-hour average of 91 µg/m³, while PM2.5 stands at 60 AQI with a 24-hour average of 13.7 µg/m³[2]. These readings indicate acceptable air quality, though some sensitive individuals may experience minor respiratory irritation.
Current ozone levels are registering at 45 AQI, which falls within the "Good" range[4]. However, residents should note that yesterday, May 9, a High Pollution Advisory was issued for ozone[3], suggesting potential for elevated levels as temperatures rise throughout the day.
The air quality trend in Phoenix has been fluctuating over the past 24 hours, with AQI levels reaching their highest point (an increase of 48) at 1:09 AM local time, while dropping to their lowest level (24) at 9:09 PM on May 3[5].
For most residents, today's air quality is satisfactory with pollution posing minimal risk. No special precautions are needed for the general public, and outdoor activities can proceed normally[5]. However, individuals with respiratory conditions such as asthma or COPD may want to monitor conditions throughout the day as temperatures rise.
Looking ahead to tomorrow, Sunday May 11, we can expect similar conditions based on the forecast patterns[2]. The recent trend shows gradually increasing pollution levels mid-week, with Wednesday's forecast showing higher concentrations across all measured pollutants.
For real-time updates, residents can check the Arizona Department of Environmental Quality website or use air quality monitoring apps. This information is particularly valuable as Phoenix enters its warmer season, when higher temperatures often correlate with increased ozone formation and potential for dust events that can affect PM10 levels.
