5 Things You Need to Know to Survive the Arizona Heat Wave

Arizona decided to skip Spring altogether this year and slide right into the impossible summer heat.

We’re fairly tough in Arizona, but surviving and even thriving in the heat isn’t about being brave—it’s about being smart. Arizona is already shattering heat records this year. The relentless heat shows no sign of slowing down.

As temperatures soar past 100°F, we’ll need to think ahead, plan well, and take the desert seriously. Here are five things we can start doing right now to stay safe.

Hydrate Like Your Life Depends On It

If you’ve heard it once, you’ve heard it a thousand times: it’s a dry heat here in Arizona. We don’t have much worry about humidity, but all that dry heat pulls moisture out of us faster than we realize.

Experts recommend drinking between 68 and 100 ounces of water a day, and even more if you’re active outdoors. Electrolytes matter too, especially when you’re sweating. If you’re feeling thirsty, you’re already behind on your water intake, so make sure you drink enough.

Plan Outdoor Time for Early Morning or Late Evening

Once temps climb above 90°F, the risk of heat illness rises sharply. Arizona State Parks and Trails recommends finishing low‑elevation hikes before 9 a.m. when it’s hot.

If the forecast hits 105°F or higher, don’t plan outdoor activities until it cools down; move those activities indoors.

Dress for the Desert

If you’re going to be in direct sunlight, exposed skin can burn quickly. It’s better to cover your arms and legs with light clothing, rather than wearing shorts and short sleeves.

AARP recommends choosing lightweight, loose‑fitting clothing, a wide-brimmed hat, and sunscreen. Sun‑protective fabrics (UPF shirts) help keep your core temperature down. Sunglasses and shade breaks are essential, especially during peak sun hours. Breathable fabrics like cotton are better than synthetics and denim to keep your skin cool.

Know the Warning Signs of Heat Illness

Heat exhaustion can sneak up on anyone. If you experience nausea, dizziness, heavy sweating, and headaches, take notice because these are early red flags.

Move into the shade, hydrate, and cool down immediately. Heat stroke is a medical emergency, so call 911 if someone becomes confused or stops sweating. To learn more about the warning signs, visit the Arizona Department of Health and Human Services (AZDHS).

Never Leave Pets or Children in a Vehicle

This goes without saying, but since heat-related tragedies do occur every year, I’m going to say it anyway: never leave children or pets in a hot car. In 80°F heat, a car’s interior can rise to 110°F after only 20 minutes of sitting with the windows rolled up.

Even with the windows cracked, the heat can reach 110°F. Don’t risk it; leave your pets at home and never leave children alone in a vehicle.
