Extreme heat can be dangerous to health by itself. It can also make pre-existing health issues worse. Some areas in the City are hotter due to elevation, limited shade from trees, and heat-retaining structures, like buildings and roads. We have a list of heat safety tips and facts below.

Never leave children and pets alone in cars. Cars heat up quickly even if the windows are slightly open.
Tips
- If you see an animal locked in a car on a hot day, find the owner as soon as possible. If you can't find the owner, call 911 or contact Animal Care and Control.
- When leaving your car, check to be sure everyone is out. Don't forget about sleeping children.
- Keep a stuffed animal in your car seat to remind yourself when a child is in the car. When the child is buckled in, place the stuffed animal in front with the driver.
Drink more water no matter how active you are. Avoid alcohol and sugary or caffeinated drinks. Don't wait until you're thirsty to drink.
Warning: If your doctor limits the amount of fluid you drink or has you on water pills, ask how much you should drink when it's hot.
Please call your utility company to report any outages. You can also call 3-1-1 with any concerns or questions.

Boston Centers for Youth & Families (BCYF) community centers become cooling centers during periods of extreme heat. Anyone can cool off inside with air conditioning. Check our updated list of cooling centers.
Due to COVID-19, all visitors will be asked to sign in with their name and contact information. They must wear a face covering (covering both the nose and mouth). Visitors must bring their own water and limit their belongings to one small bag.
The City of Boston, acting through the Office of Emergency Management, has procured misting tents as another resource to support the City during hot summer days. These tents may be available to community-based organizations (CBOs) that have public events this summer with access to potable water. The cooling kits are mobile water misting tents designed for short-term use to easily set up and disassemble and provide immediate cooling. Each cooling kit includes a hose, misters, and a tent to set up at public outdoor events throughout the summer.
Supplies are limited. We will prioritize distribution based on your ability to deploy during a heat event. Please note that kits are to be picked up at the City of Boston's Emergency Operations Center, located in Roxbury.
- Use child window guards in addition to screens on any open window on the second story or above.
- Install window air conditioners securely and insulate if necessary.
- Check air-conditioning ducts for proper insulation.
- Reflect heat back outside by installing temporary window reflectors between windows and drapes, such aluminum foil-covered cardboard.
- Weather-strip doors and sills to keep cool air in.
- Cover windows that receive morning or afternoon sun with drapes, shades, awnings or louvers. Outdoor awnings or louvers can reduce the heat entering a home by up to 80 percent.
- Keep storm windows up all year.
Limit your outdoor activity to morning and evening hours.
- If you become lightheaded, confused, weak or faint, stop all activity and find shade or a cool area to rest. Call 911 immediately if your symptoms don't improve.
- Use a buddy system when working outside.
- Let your body acclimate to the heat before you try to exercise.
