CHELSEA—The City of Chelsea Departments of Emergency Management and Public Health are sharing safety precautions with residents ahead of expected heat advisory.

Oppressive heat and humidity are expected Tuesday, June 18, through Friday, June 21, with temperatures reaching over 90 degrees multiple days in a row. High temperatures and humidity are expected to continue throughout the weekend, according to the National Weather Service.

Chelsea is considered an urban heat island, which means it can experience extreme heat conditions during the summer. On average, Chelsea is six degrees warmer than regional weather reporting indicates. The City of Chelsea reminds residents to remain vigilant against the heat and take necessary precautions when outdoors.

The City of Chelsea recommends residents utilize their air conditioners on days that are over 90 degrees.

People react differently to heat and some are at greater risk for heat related illnesses based on their age, existing health conditions, and living conditions. 

The City of Chelsea recommends the following tips to stay safe and cool:


  • Cool your home by: covering windows with drapes or shades to block off the heat from the sun 
  • Avoid Hot and Heavy Meals: They add heat to your body! And require the use of a stove or an oven. Instead, eat light meals that do not require cooking as this helps maintain a cooler temperature in your home.
  • When the temperature is above 90, stay in an air-conditioned place as much as possible. At home, you can also cool off by taking cool showers or baths. If you do not have an air conditioner, place a bowl of ice and water in front of a fan to help cool off a room. 


    • Schedule outdoor activities: Try to limit your outdoor activity to when it’s coolest, like early morning and evening hours. Stay out of the sun from about 10 a.m. to 3 p.m. 
      • Keep in mind that turf (artificial grass) and cement are 30-40 degrees hotter than grass
    • Clothing: Wear lightweight (cotton), loose fitting clothes. Dark colors attract heat. 
    • Cool Off: Walk on the shady side of the sidewalk, rest often in shady areas so that your body has a chance to recover. Use an umbrella for shade and/or a wet towel around your neck to keep cool while outdoors.
  • Pace Yourself: Cut down on exercise during the heat. If you’re not accustomed to working or exercising in a hot environment, start slowly and pick up the pace gradually. 



  • Drink Plenty of Fluids: Drink more fluids, regardless of how active you are. Don’t wait until you’re thirsty to drink. Avoid alcoholic beverages, caffeinated, and sugary drinks. And Keep Your Pets Hydrated too! 
  • Practice Sun Safety: wear sunscreen and sunglasses that filter UV light
  • Know the Signs and Symptoms of Heat Related Illnesses: 
    • Act before it is too late
