The National Weather Service (NWS) Phoenix AZ has issued an Extreme Heat Watch for several areas, including Buckeye/Avondale, Central Phoenix, and Scottsdale/Paradise Valley. Dangerously hot conditions are possible from Tuesday morning, July 7, through Thursday evening, July 9, 2026, with afternoon temperatures potentially reaching 111 to 115 degrees.
The Extreme Heat Watch was issued on July 4 at 11:28 AM MST by the NWS Phoenix AZ office. The watch is active from Tuesday morning, July 7, 2026, through Thursday evening, July 9, 2026. Areas under the watch include Northwest Valley, Buckeye/Avondale, Deer Valley, Central Phoenix, North Phoenix/Glendale, Scottsdale/Paradise Valley, East Valley, South Mountain/Ahwatukee, and Southeast Valley/Queen Creek.
Dangerously hot conditions are possible across the affected region, with afternoon temperatures forecast to be between 111 and 115 degrees. This level of heat constitutes a Major Heat Risk. Heat-related illnesses are expected to increase significantly during this period. Overexposure can lead to heat cramps and heat exhaustion, which, without intervention, may progress to heat stroke.
The NWS advises individuals to take extra precautions, especially if working or spending time outdoors. Strenuous activities should be rescheduled to early morning or evening hours when possible. It is important to know the signs and symptoms of heat exhaustion and heat stroke. Wearing lightweight and loose-fitting clothing is recommended, along with drinking plenty of water. For those engaged in outdoor work, the Occupational Safety and Health Administration (OSHA) suggests scheduling frequent rest breaks in shaded or air-conditioned environments. If someone is overcome by heat, they should be moved to a cool and shaded location; heat stroke is an emergency and requires calling 911.
Public cooling shelters may be available in some areas, and county officials can provide further details. In Maricopa County, residents can dial 2-1-1 for information on free cooling centers, transportation, and water resources. Additional information is available at http://www.maricopa.gov/heat.
