Hot Weather Safety Tips

Excessive Heat Watch

Conditions are favorable for an excessive heat warning in the next 24-72 hours.

Heat Advisory

Daytime heat indices of 100ºF–104ºF for two or more hours. The heat index is a measure of how hot it feels when relative humidity is factored in with air temperature.

Excessive Heat Warning

Daytime heat indices of greater than or equal to 105°F for two or more hours.

Learn more about the Heat Index and how it is calculated.

• Be Informed by receiving alerts, warnings, and public safety information before, during, and after emergencies.
• Create and review your family emergency plan.
• Assemble an emergency kit.
• Prepare your home for possible emergencies.
  • Install air conditioners snugly, insulating if necessary.
  • Cover windows that receive morning or afternoon sun. Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.

• Never leave children or pets alone in a closed vehicle. Even with the windows cracked open, interior temperatures can rise almost 20°F within 10 minutes.
• Slow down and avoid strenuous activity.
• Wear lightweight, loose-fitting, light-colored clothing. Light colors reflect heat and sunlight, and help maintain normal body temperature.
• Drink plenty of water — even if you are not thirsty. Avoid alcoholic beverages and liquids high in sugar or caffeine. If your doctor generally limits the amount of fluid you drink, ask how much you should drink during hot weather.
• Eat well-balanced, light, regular meals.
• Stay indoors as much as possible and limit exposure to the sun. Do not leave pets outside for extended periods of time.
• If you must be outdoors, limit your outdoor activity to the morning and evening hours. Try to rest often in shady areas so your body temperature will have a chance to recover. Use sunscreen with a high SPF and wear a wide-brimmed hat.
• If you do not have air conditioning, stay on your lowest floor, out of the sun. Use fans to stay cool and avoid using your stove and oven. Consider spending time in air-conditioned public spaces, such as schools, libraries, theaters, and other community facilities.
• Check with your local authorities or Call 2-1-1 to find locations of cooling centers or shelters near you.
• On hot days, more people cool off around bodies of water. Playing in and around water can increase the risk of drowning. Learn how to keep yourself and your children safe in and around water with these Water Safety Tips.
• If there are power outages during warm weather, you may need to take additional precautions or go to a cooling center or emergency shelter to stay cool.
• Know the symptoms of and watch out for heat-related illnesses. Call 9-1-1 to report emergencies.
• Be a good neighbor. Check on family, friends, and neighbors, especially the elderly, those who live alone, those with medical conditions, those who may need additional assistance, and those who may not have air conditioning.

During extreme heat, people are susceptible to three heat-related illnesses. Learn how to recognize and respond to them:

• Heat cramps are muscular pains and spasms caused by heavy sweating.
  • Symptoms: Muscular pains and spasms that usually occur in the legs or abdomen
  • Treatment: Get the person to rest in a comfortable position in a cooler place. Give the person water or fluids with electrolytes help them rehydrate.
• Heat exhaustion typically occurs when people overexert themselves in a warm, humid place, and often affects those doing strenuous work in hot weather. Body fluids are lost through heavy sweating and blood flow to the skin increases, causing blood flow to vital organs to decrease. This results in a form of mild shock.  
  • Symptoms:  Cool, moist, pale or flushed skin, nausea, dizziness, headache, weakness, and/or exhaustion
  • Treatment: Get the person to rest in a comfortable position in a cooler place. Remove or loosen tight clothing and apply cool, wet cloths, such as towels or sheets. If the person is conscious, give them half a glass of cool water or fluids with electrolytes every 15 minutes, making sure the person drinks slowly. Watch the person carefully for changes in his or her condition and call 9-1-1 if it doesn’t improve.
• Heat stroke is the most serious heat emergency and is life-threatening. Heat stroke develops when systems in the body begin to stop functioning due to extreme heat. Heat stroke may cause brain damage or death if the body is not cooled quickly.  
  • Symptoms: Extremely high body temperature, hot and red skin (dry or moist), loss of consciousness, changes in level of responsiveness rapid and weak pulse, rapid and shallow breathing, vomiting, confusion, and/or seizures
  • Treatment: A person suffering from heat stroke needs immediate assistance. Call 9-1-1 and move the person to a cooler place. Immerse the individual in a cool bath, wrap in cold wet sheets, or cover the person in bags of ice.

In cases of extreme hot weather, the City will set up designated cooling centers at public spaces to help keep the community safe. Please check social media feeds, including Facebook and Twitter, and news posts for the latest updates on cooling centers.

Cooling centers are at the following locations:

• Medford Police Department Community Room (100 Main St.), available 24 hours a day  

• Medford Senior Center (101 Riverside Ave.), from 9am-4pm (Monday-Friday)
