Markham has issued a heat warning due to the local forecast indicating temperatures above 30 Celsius with a high humidex on Thursday, August 4 and Friday, August 5, 2016. It is important to take precautions to avoid suffering heat-related illnesses. 

Local Forecast 

Thursday, August 4 
Sunny. High 31. Humidex 38. 
Night - Clear. Low 21. 

Friday, August 5 
A mix of sun and cloud with 40 percent chance of showers. High 31. 
Night - Cloudy periods with 40 percent chance of showers. Low 17.


Markham recommends the following based on Health Canada guidelines:

  • Drink plenty of cool liquids, especially water, to decrease your risk of dehydration.
  • Wear loose-fitting, light-coloured clothing made of breathable fabric.
  • Keep people and pets in your care out of parked vehicles and direct sunlight.
  • Spend a few hours in a cool place - a tree-shaded area, swimming facility or an air-conditioned building such as a shopping mall, grocery store, place of worship or public library.
  • Take cool showers or baths.
  • Prepare meals that don't need to be cooked in your oven.
  • Block sunlight by opening awnings, and closing curtains and blinds during the day.
  • Avoid sun exposure - shade yourself by wearing a wide-brimmed, breathable hat or using an umbrella.
  • If you are taking medication or have an existing health condition, ask your doctor or pharmacist if heat exposure increases your health risk and follow their advice.
  • If you have an air conditioner with a thermostat, keep it set to somewhere between 22ºC (72ºF) and 26ºC (79ºF), which will reduce your energy costs and provide you with needed relief.
  • If you have a window air conditioner, cool only one room where you can go for heat relief.
  • Frequently visit friends, neighbours, and elderly family members, especially those who are chronically ill, to make sure they are cool and hydrated.
  • Reschedule or plan outdoor activities during cooler parts of the day.
