During extreme heat

Prepare your family or business for an emergency

Heat waves in Calgary are a potential concern during June, July and August. Calgary summers are getting increasingly hotter and drier. Extreme heat can put your health at risk, causing illnesses like heat stroke and even death. When the temperature rises, know how to stay safe.

Tips to avoid a heat stroke

  • Avoid working or exercising intensely in the heat or humidity. If it cannot be avoided, be sure to take regular breaks, drink lots of water, maintain salt levels in your body and avoid high-protein foods.
  • Drink plenty of water before you feel thirsty to decrease your risk of dehydration.
  • Have cool drinks in your vehicle and keep your gas tank topped up.
  • Wear sunscreen.
  • Never leave people or pets inside a parked vehicle or in direct sunlight. Ensure pets have plenty of water.
  • Dress for the weather by wearing loose fitting clothes, a brimmed hat and UVA and UVB protected sunglasses.
  • Keep your home cool by closing curtains and blinds during the day. If you have an air conditioner, make sure it is working properly. If you have fans, they can help in low humidity. Open windows for cooler air if safe to do so and avoid using your oven if possible, as it will heat up your home.
  • If your home is too hot and uncomfortable, take cool showers or baths or go to an air conditioned public space, like a shopping mall.
  • Tune in regularly to local weather forecasts so you know when to take extra care.

Health Canada has additional information about extreme heat as well as sunburns and heat illnesses.

Heat stroke is a medical emergency

Call 9-1-1 immediately if you or others experience abnormal symptoms and watch for signs of serious medical conditions. Move immediately to a cool place and drink water if you experience any of these symptoms during hot weather:

  • dizziness
  • fainting
  • nausea or vomiting
  • headache
  • rapid heartbeat or breathing
  • dehydration

After extreme heat

  • Remember to check up on your family or friends who are alone and do not have air conditioning.
  • Continue to hydrate and protect yourself and your family from heat‐related illness.
  • Take this time to refurbish and outfit your home for the next extreme heat season.
