Hot Weather and COVID-19

UPDATED Last updated: June 3, 2021

Extreme heat is a potential risk for everyone. Staying safe while it is hot, drinking enough water and staying cool on hot days is important but, may be more difficult during the COVID-19 pandemic. Follow these public health measures to ensure you can safely enjoy the warmer weather.

  • Stay hydrated and pack extra water when you go out. Many public fountains are closed and not all retail stores are open for purchases, which limits access to water or beverages.
  • Check the hours of public spaces and facilities you visit to cool off. Hours of operation may be modified under COVID-19.
  • Respect all public health measures about physical distancing when you using swimming pools or splash pads or when visiting beaches, parks or indoor cooling spacesá
  • Anyone can put themselves at risk by over-exercising in hot weather because the body has to work even harder to stay cool. Stay hydrated and plan activities for cooler parts of the day or exercise in an air conditioned space while respecting social (physical) distancing measures.
  • Some medications can also increase your risk of being affected by the heat, so it’s important to ask your doctor or pharmacist whether the medication you’re taking affects your ability to cope with heat. View a fact sheet on medications and heat. áCertain substances, including amphetamines, MDMA (ecstasy), cocaine, alcohol and cannabis, can alter mental status as well as increase the risk of over-heating. 
  • Vulnerable populations should take extra care. Heat can stress the body and reduce a person’s capacity to fight off COVID-19. The virus may also affect some people more than others. Vulnerable populations include:
    • older adults
    • infants and young children
    • people with chronic conditions, such as breathing difficulties or heart problems
    • people who work or exercise in the heat (even if they are healthy)
    • other vulnerable people, ápeople experiencing homelessness
  • Ensure you check in regularly with vulnerable or socially isolated community members, friends and family.  Contact people by phone where possible to reduce face-to-face interactions.
