A dangerous stretch of extreme heat will impact much of south-central Arizona, including Phoenix, through Tuesday, with temperatures soaring to as high as 115°F and overnight lows that won’t dip below 90°F in some areas.
This intense heat is expected to last through Tuesday, with an Extreme Heat Warning issued by the National Weather Service in Phoenix from Sunday, June 29, through Tuesday, July 1.
Extreme Heat in Phoenix and Surrounding Cities
Cities including Glendale, Mesa, Chandler, and Buckeye are under alert, with the hottest conditions expected to occur on Monday. As the temperature rises, residents are urged to take precautions to protect themselves from heat-related illnesses. Maricopa County is offering free rides to cooling centers daily from 8 a.m. to 5 p.m. through Arizona 211, providing residents access to air-conditioned spaces.
Safety Measures and Risks
During this extreme heat, it is crucial to stay indoors between 10 a.m. and 6 p.m., when the sun is at its peak. Drinking water frequently is important to stay hydrated, and residents are advised to avoid strenuous outdoor activity.
Air conditioning is strongly recommended, as fans alone may not provide sufficient relief. Vulnerable groups, such as pets, elderly residents, and outdoor workers, are at the highest risk of experiencing heat-related illnesses.
Monsoon Storms Expected Midweek
While the extreme heat will persist through Tuesday, a monsoonal shift is expected to bring some relief starting Wednesday. As moisture from Mexico builds, slight storm chances are possible in the Phoenix area, with higher elevations likely to experience gusty winds and scattered thunderstorms. The monsoon conditions will be closely monitored, with additional warnings and advisories possible as the storm pattern develops.
Stay Updated and Prepare for the Heat
The Extreme Heat Warning will remain in effect through Tuesday night, and residents should remain vigilant for further updates. Stay cool, hydrated, and informed as temperatures soar and the monsoon pattern begins to shift midweek.
