How to Prepare for Extreme Cold and Stay Safe: Guidance Checked November 5, 2026

Guidance checked: November 5, 2026, at 9:09 p.m. UTC (UTC+00:00).

Extreme cold can turn a routine trip, a power outage, or a night in a poorly heated home into a health emergency. Before temperatures fall, check the forecast for your exact location, prepare a warm place to shelter, and make a plan for anyone who may need help.

This is practical preparation guidance for readers in Australia, not a report of a confirmed current cold warning. Conditions and official warnings differ by location, so check the Bureau of Meteorology and your state or territory emergency service for the latest advice before acting.

Destaques

• Check local forecasts and road conditions, and change travel plans if severe weather is expected.
• Wear loose layers, stay dry, and arrange regular breaks in a warm place.
• Prepare food, water, medication, lighting, and a safe way to stay warm if power fails.
• Confusion, slurred speech, or worsening drowsiness after cold exposure may signal hypothermia. Call triple zero (000) for an ambulance.

What should you do before extreme cold arrives?

Start with the forecast for the places where you will actually be: home, work, school, and any planned travel route. Check it again before leaving, because temperature, wind, rain, and snow conditions can change. Follow any instructions from local authorities and postpone nonessential travel if conditions are dangerous.

Make a household plan that covers where you will stay warm, how you will contact one another, and what you will do if electricity or phone service is interrupted. Include pets, medical needs, and anyone who depends on powered equipment. If you use medical equipment that needs electricity, discuss a backup plan with your equipment supplier and healthcare provider before an outage.

Put essentials somewhere easy to reach: drinking water, long-life food, regular medication, a first-aid kit, warm clothing and blankets, a flashlight, spare batteries, and a charged phone and power bank. The NSW State Emergency Service snow guidance recommends keeping food and water that can last several days because roads and communities can become isolated.

Check on older relatives, neighbors, people with limited mobility, and others who may find it difficult to heat their homes or get supplies. Agree on when you will contact them and who can help if you cannot reach them.

How should you dress for extreme cold?

Wear several loose layers so you can adjust your clothing as conditions change. Add a wind- and water-resistant outer layer when needed, and protect your head, hands, and feet. Keep spare dry clothing available: wet clothes can accelerate heat loss, so change out of them as soon as you safely can.

Limit time outdoors and schedule warm-up breaks, especially if you work outside or are hiking. Eat and drink enough, and avoid relying on alcohol to feel warm. Healthdirect notes that hypothermia can happen in any season, including indoors, when the body loses heat faster than it can replace it.

Cold, wind, and wet conditions can combine to make exposure more dangerous than the air temperature alone suggests. Babies and young children, older adults, people with poor circulation or reduced mobility, and people taking certain medications may face greater risk. Ask a healthcare professional about individual precautions if you are unsure.

How can you heat your home safely?

Have gas heaters serviced by a qualified gasfitter and follow the appliance instructions. Keep required vents clear. Energy Safe Victoria advises that open-flued gas heaters need adequate airflow and warns against running kitchen or bathroom exhaust fans at the same time, because they can draw dangerous gases into living areas. Its gas-heating guidance also says a carbon monoxide alarm is a useful backup, not a substitute for servicing.

Never bring outdoor gas appliances indoors for heat, and do not use a barbecue or outdoor cooking device inside a home, garage, or tent. Carbon monoxide is colorless and odorless. If you suspect exposure, move into fresh air, call 000 for an emergency, and do not use the suspected appliance until it has been checked by a qualified professional.

If the power goes out, put on dry layers and gather in a safely heated room if one is available. If your home cannot be kept safely warm, arrange to stay with someone or use a shelter identified by local authorities. Check the forecast and service updates before traveling there.

What should you pack if you must travel?

Check official road reports as well as the weather forecast. Tell someone your route and expected arrival time, charge your phone, and carry water, food, blankets, warm clothing, medication, and a flashlight. In snow-prone areas, check local requirements for snow chains and make sure you know how to fit them before setting out.

If conditions deteriorate, stop somewhere safe and follow emergency-service instructions. If you become stranded, call for help when possible and give your location. Stay with your vehicle unless authorities direct you otherwise or remaining there is unsafe. Do not run an engine in an enclosed space; exhaust fumes can be deadly.

What are the signs of hypothermia, and what should you do?

Early signs can include shivering, cold skin, clumsiness, difficulty speaking, and unusual tiredness. Confusion, slurred speech, increasing drowsiness, or a person who stops shivering may indicate worsening hypothermia. Someone affected may not recognize the danger themselves.

Hypothermia is a medical emergency. Call 000 for an ambulance if you suspect it, particularly if the person is confused, drowsy, or unconscious. While waiting, move them gently to a warm, dry place if safe, remove wet clothing, keep them still, and cover them with blankets. Give a warm, sweet drink only if they are awake and responding. Do not use a hot bath, shower, or direct heat to warm them. If they are not breathing normally, start CPR and follow the emergency operator’s instructions.

What should you watch for as conditions change?

A forecast is a prediction, not a guarantee. If colder weather, snow, or strong winds are forecast, check updates regularly and be ready to change plans. A power outage or road closure can last longer than expected, so replenish supplies after using them and keep your support contacts informed.

For location-specific forecasts and warnings, use the Bureau of Meteorology and your state or territory emergency service. For non-emergency health advice, healthdirect lists its nurse helpline as 1800 022 222; call 000 when an ambulance is needed.

Frequently asked questions

Can you get hypothermia indoors?

Yes. A cold home, wet clothing, illness, or prolonged contact with a cold surface can contribute to hypothermia, particularly for someone who cannot move around or keep warm easily.

Should you drink alcohol to warm up?

No. Alcohol can make you more vulnerable to cold. Choose a warm nonalcoholic drink and move to shelter instead.

Does an Australian frost warning mean every area nearby will freeze?

No. Frost depends on local conditions, and warnings have a specific geographic scope. Check the forecast for your location; the Bureau says its frost warnings in Tasmania, Victoria, and South Australia concern conditions likely to damage frost-sensitive plants.
