How to Stay Safe During Extreme Heat

Hot weather and extreme heat can cause serious illness and can even be life-threatening. Heat-related illnesses, like heat stroke and dehydration, can occur.

During heat waves, residents are encouraged to 
spend time in air-conditioned places like malls, movie theaters, and public libraries. Cambridge Public Branch libraries will welcome people seeking to cool off during regular hours and will have water bubblers available. Branch hours and locations can be found on the City’s website.

Outreach teams and extended hours at select emergency shelters will be utilized to support the unhoused community during extended heat waves. Outreach teams will be distributing water, cooling towels, popsicles, sunscreen, non-perishable snacks and juice boxes.

If you are concerned about a person who is unhoused, please call First Step at (617) 592-6895 or call 911 if the person is experiencing an emergency. 
 

As the weather heats up, pet safety becomes a “HOT” animal welfare issue. The Cambridge Animal Commission WANTS to remind you that leaving a pet inside a parked car is the most common cause of deadly heat stroke.

REMEMBER:

  • Leaving your pet in a hot car for even a short time could kill your pet.
  • Even with all the windows cracked, the temperature of your car can reach deadly levels quickly.
  • Pets do not sweat the way humans do.  They CANNOT cool their bodies efficiently in hot temperatures.
  • Protect your dog’s paws, use the 7-second rule. Place your hand on the ground surface. If it’s too hot for your hand, then it’s too hot for your dog.

Please leave your pets at home in warm weather.  They will be happy to see you when you return!

DPW is working with employees and the public about managing energy usage this summer to help reduce the strain on the region’s power grid.

    • Contact your local electric company and equipment suppliers about your power needs. Some utility companies will put you on a "priority reconnection service" list;
    • Let the fire department know that you are dependent on life-support devices; and
    • If you have medication that requires refrigeration, check with your pharmacist for guidance on proper storage during an extended outage.
  • Monitor the weather. Watch your local news or visit National Weather Service–Boston for advisories and alerts.

What should I do during a power outage?

  • Check current power outages in the state with the Power Outage Map done by Massachusetts Emergency Management Agency.
