Extended Heat Warning issued for Burlington, Oakville, Milton


Published September 5, 2023 at 9:59 am

Halton Region Public Health has issued an Extended Heat Warning for Burlington, Oakville, Milton and Halton Hills.

An Extended Heat Warning is issued when the daytime temperatures reach at least 31C with overnight temperatures above 20C for three or more days, or when the humidex is expected to reach 40 for three or more days.

High body temperature can lead to heat stroke, heat exhaustion, heat fainting, swelling of hands, feet and ankles, heat rash and heat cramps.

Symptoms of heat illness include dizziness or fainting, nausea or vomiting, headache, rapid breathing and heartbeat, extreme thirst and decreased urination.

Pay close attention to how you, and those around you, feel. If you experience symptoms of heat illness, immediately move to a cool place and drink liquids. Water is best.

Heat stroke is a medical emergency. Call 9-1-1 when someone has a high body temperature and is either unconscious, confused or has stopped sweating. Cool the person as best you can while waiting for medical attention to arrive.

Quick tips on how to take action and protect your health:

  • Drink plenty of cool liquids, especially water, before you’re thirsty
  • Avoid sun exposure, wear a wide-brimmed hat
  • Wear loose-fitting, light-coloured clothing
  • Take a break from the heat by going somewhere cool
  • Visit your neighbours to make sure they are cool and hydrated
