Heat Warning for Saturday and Sunday

July 4, 2025

 

Environment Canada has issued a two day heat event that is expected Saturday and Sunday covering all of Wellington, Dufferin and Guelph.

Humidex values reaching 40 are expected. Daytime highs of 31 to 33 degrees Celsius and a humidex of 40 with overnight lows of 21 to 25 degrees Celsius, providing little relief from the heat.

Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.

Protect yourself and others by:

  • Knowing the forecast and being on the lookout for heat warnings
  • Having a plan to take breaks from the heat
  • Remembering that children, the elderly and those with chronic conditions are at higher risk of heat-related illness
  • Staying hydrated by drinking plenty of water or juice
  • Never leaving people or pets inside a parked vehicle
