Philadelphia, PA – A code orange air quality alert is in effect through Sunday for the Philadelphia metro, with temperatures climbing to 90 degrees Monday under mostly sunny skies. Sensitive groups, including children, older adults, and those with asthma or heart and lung conditions, should limit outdoor exertion until conditions improve.
According to the Delaware Valley Regional Planning Commission and the National Weather Service, the alert affects Philadelphia along with Delaware, Bucks, Montgomery, and Chester counties. Ground-level ozone levels could reach unhealthy ranges, especially in the afternoon and early evening hours. Light winds and high pressure are trapping pollutants, making air quality a concern through Sunday night.
Outdoor plans Monday will come with heat and strong sunshine, but without significant humidity spikes, making it a good day for activities if precautions are taken. Keep hydrated, wear light clothing, and apply sunscreen if outdoors for extended periods.
The heat will intensify Tuesday, reaching 92°, before midweek brings a chance for thunderstorms and slightly cooler air. Air quality is expected to improve after Sunday’s alert expires, but another round of heat could keep ozone levels elevated later in the week.
