Did you know?
Cars are a heat hazard
Temperatures inside your car can skyrocket to life-threatening levels within minutes, reaching temperatures hot enough to bake cookies. Even on an 80°F day, the inside of a car can reach 109°F in just 20 minutes. Parking in the shade or leaving the windows rolled down does not lower temperatures.
- Never leave children, older adults, individuals with disabilities, or pets in a parked car, even for a “quick” errand.
- Make it a habit to double-check the back seat and the entire vehicle to ensure everyone has exited before you lock up.

Safety Tips:
Stay Cool
- Limit your outdoor activity to when it’s coolest, like morning and evening hours
- Find your nearest heat relief site (cooling center, respite center, hydration station) for free access to air conditioning and water
- Do not leave children or pets alone in a parked car. The temperature inside can rise quickly and become deadly
Stay Hydrated
- Drink plenty of water throughout the day
- Avoid alcohol and drinks with high caffeine or sugar
Stay Informed
- Look out for signs and symptoms of heat-related illnesses: dizziness, muscle cramps, nausea, headache, and confusion
- Check the weather forecast for temperature, air quality, and UV index
- Learn more about today’s NWS HeatRisk map
Stay Connected
- Check on your family, friends, pets, and neighbors, especially those who are sensitive to heat, such as individuals over 65, those with chronic medical conditions, people living alone, and those who are unhoused
- Share your location with friends and loved ones before taking a road trip, hiking, or camping and use Arizona 511 for road conditions and traffic information
Be SunWise
- Limit sun exposure with sunglasses, hats, and lightweight clothing
- Use SPF 30+ sunscreen to protect your skin from UV rays
