Phoenix and central Arizona are facing dangerously high temperatures today, with the mercury expected to soar to a blistering 113°F by mid-afternoon. The National Weather Service has issued an Extreme Heat Warning until 8 p.m. Tuesday, urging residents to take immediate precautions to protect themselves from the extreme heat.
Heat Warning and Safety Tips
With temperatures climbing into the 111°F to 115°F range across Maricopa County—including Phoenix, Scottsdale, Glendale, and Mesa—heat-related illnesses are a major concern.
Residents are strongly advised to limit outdoor activities and find cool, shaded places to stay. The risk of heat exhaustion is high, and if untreated, it can quickly lead to heat stroke, which can be life-threatening.
Emergency officials recommend calling 2-1-1 for assistance in locating nearby cooling centers or getting help with transportation to these shelters. More resources and information are available at maricopa.gov/heat.
For those who must be outdoors, it’s crucial to carry extra water, wear light, breathable clothing, and take regular breaks in shaded or air-conditioned spaces. Avoid leaving children or pets in vehicles, even for a brief moment. Outdoor workers should schedule frequent rest breaks to stay safe in the extreme heat.
The heat won’t be limited to Phoenix alone—Goodyear, Tempe, Chandler, and Queen Creek are also included in the warning zone. With clear skies and light winds, the extreme temperatures will persist well into the evening.
What to Expect in Phoenix This Week
The intense heat will continue through the week, but there are slight signs of relief ahead.
Here’s the forecast for Phoenix through the July 4th weekend:
Wednesday, July 2: Expect a high of 107°F with a slight chance of evening storms. It will be breezy overnight.
Thursday, July 3: The high will reach 102°F, with isolated storms possibly rolling in during the afternoon.

Phoenix’s extreme heat is no joke, and it’s essential to take steps to protect yourself and others. If you can, stay indoors and keep hydrated throughout the day, even if you’re not feeling thirsty.
Be mindful of the signs of heat exhaustion, which can include dizziness, excessive sweating, nausea, and confusion. If you or someone else shows signs of heat stroke, it’s critical to seek emergency help right away.
