Arizona is experiencing dangerously high temperatures this week, with triple-digit heat pushing temperatures up to 118°F in some areas. These extreme conditions are expected to last until Friday evening, putting millions of residents at risk for heat-related illnesses.
Extreme Heat Warning Details
An Extreme Heat Warning has been issued by the National Weather Service in Phoenix for Maricopa, Pinal, and surrounding counties. The warning will stay in effect through 8 p.m. Friday.
During this time, temperatures will range from 106°F to 118°F, which increases the risk of heat exhaustion or heat stroke, especially for those working outdoors or lacking access to air conditioning.
In Phoenix, Scottsdale, and Glendale, public cooling centers are open to provide relief. Residents are encouraged to call 2-1-1 or visit Maricopa.gov/Heat for resources such as transportation assistance and hydration stations. It’s crucial for people in these areas to stay cool and avoid extended outdoor activity during the hottest parts of the day.
High Temperatures in the Grand Canyon and Tucson
The Grand Canyon is also feeling the heat, especially below 4,000 feet. Locations like Phantom Ranch are expected to see temperatures of up to 113°F. Hikers are urged to limit their time outdoors and stay near water sources to prevent dehydration and heat-related illnesses.
In Tucson and surrounding areas, including the Tohono O’odham Nation, Willcox, and the Upper Gila River Valley, temperatures will reach up to 115°F starting Thursday. This extreme heat will pose additional risks for outdoor workers, children, and elderly residents. Extra caution is needed for vulnerable groups.
Safety Recommendations
Officials strongly recommend rescheduling outdoor activities, drinking plenty of fluids, and checking on neighbors, particularly the elderly, young children, and those with pre-existing health conditions. OSHA advises workers who need to be outside to take frequent breaks in shaded areas or air-conditioned spaces to minimize the risk of heat exhaustion or heat stroke.
This extreme heat is expected to persist through Friday evening, and additional alerts could be issued if conditions worsen.
Arizona’s extreme heat continues to push temperatures to dangerous levels, particularly in cities like Phoenix, Scottsdale, and Tucson. With afternoon highs hitting over 100°F, residents should take all necessary precautions to stay cool, hydrate, and protect themselves from the intense heat.
Cooling centers are available for those in need, and public health officials continue to emphasize the importance of avoiding outdoor activity during the hottest hours.
