Cold Weather

Cold weather can be dangerous, but we’re here to help you stay safe and warm. This page will guide you through what to do during extreme cold, how to dress properly, where to find warming centres, and how to recognize cold-related health risks like frostbite and hypothermia. Let’s keep you and your loved ones safe this winter.

How do you know when a cold weather alert is issued?

Southwestern Public Health (SWPH) issues cold weather alerts when:

• Temperatures drop to -15°C without wind chill, or

• Temperatures drop to -20°C with wind chill

To stay updated, follow us on social media or check local news for announcements. 

What should you wear to stay warm?

Dressing properly in layers can make all the difference in extreme cold:

• Layer your clothing:

• Inner layer: Moisture-wicking fabric (e.g., merino wool or synthetic)

• Middle layer: Insulating material like fleece or down

• Outer layer: Windproof and waterproof shell

• Wear insulated accessories:

• Hat, mittens (better than gloves), scarf, and insulated boots

• Carry extras: Keep spare socks and gloves in case your current pairs get wet.

How can you recognize and treat frostbite and hypothermia?

Frostbite

• What to look for: Pink or white waxy skin, numbness, pain in fingers, toes, ears, or nose.

• What to do:

• Warm affected areas with skin-to-skin contact or warm (not hot) water

• Avoid rubbing the area

• Seek medical attention if severe

Hypothermia

• What to look for: Shivering, confusion, pale skin, and lethargy. Severe cases may involve unconsciousness.

• What to do:

• Move to a warm area and remove wet clothing

• Wrap the person in blankets

• Call for emergency medical help immediately

Where can you go to stay warm?
