Extreme Heat Communications and Social Media Toolkit

A resource for Massachusetts cities and towns

Of all weather-related hazards, extreme heat is responsible for the most deaths annually. In 2022, there were 49 days in Massachusetts where temperatures exceeded 90F. Compared to the averaged 11 days a year from 1971-2000, this increase in extreme heat days is of great concern especially for vulnerable populations (seniors, children, etc). In the Northeast, higher temperatures cause poor air quality, exacerbating existing health conditions. 

Staying safe in extreme heat is essential in the summer, especially for those without air conditioning. On this page, we've compiled flyers, sample social media posts, and images that cities and towns can use to spread the word to their followers.

Social Media Basics: How to Post

Social Media Tips and Best Practices
  •  Know Your Audience: Who are you posting this information to? Residents? Create your social posts with that audience in mind. 
  • Know the Platform: The social media platform you are using to post on should inform how and what you're posting. For example, posting on Twitter is for more immediate, word-limited posts. LinkedIn is for professional audiences, and there isn't a word limit.  Facebook is for more casual posts. You can use the same post across platforms, but we recommend slight modifications to cater to each form of media. 
  • Accessibility: Ensure your social posts are accessible to all by making sure to provide a written description of the images used to your caption (known as alternative text), and if you use hashtags, capitalize the first letter of each word. Learn about ways to make your posts accessible. 
  • Interactive: Amplify other social media accounts such as official sources, agencies, and experts, by sharing or retweeting their posts. Be sure to use the Stories function on Facebook and Instagram for this. 
  • Tag Us! Be sure to tag MAPC in your social posts to reach a larger audience. Please feel free to also retweet any posts we do as well.

Staying Cool: General

Heat affects us all, but some of us are at greater risk. Different people react differently to heat based on their age, health, and living conditions. Check in on your neighbors, friends, and family on hot days to make sure they’re staying cool!

Prepare for hot days! Monitor local weather reports so you know to prepare for very hot days: in the Boston area, days over 90 degrees are considered very hot.  

Where will you cool off? With a big heat wave coming up, have a plan if you don’t have air conditioning. Do you have family or friends with AC that you feel comfortable visiting? Ask them if you can come over if the day gets too hot.  

Going outside? Remember your water bottle! It’s important to stay hydrated on hot days, even if you’re not thirsty. Caffeine, alcohol, and sugary drinks may dehydrate you. #KeepCool 

Headed outdoors? Remember to dress for hot days: wear sunscreen and loose-fitting, light-colored clothing. Bring a wide-brimmed hat, sunglasses, and water!  

It’s going to be over 90 degrees (today/this week/next weekend). This heat can be dangerous: avoid exercise or strenuous activity during the hottest parts of the day, instead, try to go out in the morning or evening. 

It’s going to be over 90 degrees (today/this week/next weekend). This heat can be dangerous. If you must be outside, take breaks, stay out of direct sunlight, and look for shade trees!  

Be a good neighbor: check on family, friends, and neighbors ahead of and on hot days. Make sure they have air conditioning or somewhere to go to keep cool.
