These hot temperatures aren’t going away any time soon in Oakville and Burlington and the rest of Halton Region.

Halton Region has issued an extended heat warning through Friday (July 28) and into the weekend.

This follows on the heels of a heat warning issued by the region earlier in the week on Wednesday.

The warnings are issued when daytime temperatures are expected to climb to at least 31 C (Celsius) with overnight temperatures staying above 20 C.

The hot temperatures can be dangerous to the elderly, children and those with heath issues.

Dr. Jonathan Sam, Chief of Paediatrics at Oakville Memorial Trafalgar Hospital and Georgetown Hospital, said the temperatures can especially put children at risk.

“Summer’s here and it’s super exciting, but it also means the kids are outside more and there are more risks for consequences of being in the heat,” Dr. Sam said in a recent online video.

Extreme heat and humidity is a potential danger to all. Factors such as obesity, dehydration, fever, infection, sunburn and alcohol abuse can increase a person’s risk.

Those at greatest risk include:

  • Older adults (over the age of 65)
  • Infants and young children

  • People with physical or mental disabilities
  • People who work in the heat
