Arizona is a diverse state with many elevations, and there are many parts of the state that enjoy cool, comfortable temperatures all summer.

By following this hot-weather advice provided by the Arizona Department of Health Services, you’re sure to appreciate all the wonderful attractions that Arizona has to offer this time of year.
When Outdoors
- Use sunscreen: Wear a sunscreen with a minimum SPF 15. Apply at least 30 minutes before going outdoors and reapply as needed.
- Take breaks in the shade: Rest frequently in shaded areas to allow your body temperature to recover.
- Acclimate gradually: If you're not used to working or exercising in the heat, gradually increase your pace and limit your time outdoors.
- Dress appropriately: Wear lightweight, loose-fitting clothing, sunglasses to protect your eyes, and a wide-brimmed hat to keep your head cool.
- Protect infants and young children: Dress them in loose, cool clothing, shade their heads and faces with a hat or umbrella, and protect their feet with shoes.
How To Avoid Heat-Related Illness
- Never leave infants, children, or pets in a parked vehicle: Even for a short time, temperatures can rise rapidly and become deadly.
- Stay hydrated: Increase fluid intake regardless of activity level. Don’t wait until you’re thirsty to drink—drink more than your thirst indicates.
- Prevent “heat hangover”: Continue hydrating after strenuous activity to help avoid headaches and fatigue caused by heat exposure.
- Avoid dehydrating drinks: Stay away from beverages containing alcohol, caffeine, or large amounts of sugar, as they can dehydrate the body.
- Skip icy drinks: Very cold beverages can cause stomach cramps—opt for cool but not ice-cold fluids.
- Limit midday activity: Avoid exercise or outdoor activity between 11 a.m. and 3 p.m. when the sun is strongest. If active, drink 16–32 oz. of water per hour.
- Cool your home: If you don’t have air conditioning, pull shades over windows and use fans or cross-ventilation to keep rooms cool.
- Take a cool shower or bath: This can quickly help lower body temperature.
- Check medications: Some prescription or over-the-counter drugs may increase heat-related illness risk. Ask your doctor if you're unsure.
