Extreme Weather Safety for Families: Preparing Children for Floods, Heatwaves, and Storms

Extreme Weather and Families

Extreme weather events are becoming more frequent and more severe across many parts of the world. Floods, heatwaves, severe storms, wildfires, and other extreme weather events that once seemed rare are increasingly part of the lived experience of families in many regions. Being prepared for the specific weather risks in your area, and knowing how to keep children safe during such events, is a practical and increasingly important aspect of family safety.

Children experience extreme weather differently from adults. They are more vulnerable physically: overheating faster in heatwaves, having less physical reserve in cold conditions, and being less able to self-rescue in flood or storm situations. They are also more likely to be frightened by dramatic weather events. Preparation, calm communication, and age-appropriate information all help children feel safe rather than overwhelmed when extreme weather occurs.

Heatwave Safety

Heatwaves pose specific risks to children, particularly very young children and babies, who are less able to regulate their own body temperature and who cannot communicate thirst reliably. Key heatwave safety principles for families:

• Keep children out of the sun during the hottest part of the day, typically between 11am and 3pm. Plan outdoor activities for early morning or evening.
• Ensure children drink fluids regularly and frequently. Do not wait until they say they are thirsty, as children often do not notice or report thirst until they are already mildly dehydrated.
• Dress children in loose, light-coloured clothing in natural fabrics. Apply high-factor sunscreen if any sun exposure is likely.
• Keep indoor spaces cool: close blinds and curtains on sun-facing windows during the day, open them at night when the air is cooler.
• Never leave children in parked vehicles, even briefly. Temperatures inside a car can reach dangerous levels within minutes on a hot day.
• Watch for signs of heat exhaustion in children: pale, clammy skin, weakness, dizziness, nausea. Move the child to a cool place, offer cool fluids, and cool with damp cloths. If there is no improvement rapidly, seek medical help.
• Heat stroke, which involves hot, dry skin, confusion, and loss of consciousness, is a medical emergency requiring immediate emergency services.

Flood Safety

Flood events can escalate rapidly and without warning in some conditions. The key principle of flood safety is to treat any flood water as hazardous and to act early rather than waiting to see if the situation worsens.

• Never walk, wade, or drive through flood water. Moving flood water is far more powerful than it appears: as little as 15 centimetres of fast-moving water can knock an adult off their feet. Flood water also frequently contains sewage, chemicals, and debris, and conceals hazards including open drains and manholes.
• If flooding is forecast for your area, prepare by moving important items upstairs, protecting electrical items, and having your emergency go-bag ready.
• Know the route to higher ground from your home and from other places your family regularly spends time.
• Follow official advice. If authorities advise evacuation, leave early and take children and pets. Do not wait to see if it floods.
• After flooding, treat all surfaces that have been in contact with flood water as potentially contaminated. Wash hands thoroughly and frequently. Do not allow children to play in or near flood water even after it has receded.

Storms and High Winds

Severe storms and high winds bring risks including flying debris, flooding, and power outages. During a storm warning:

• Stay indoors and away from windows
• Secure or bring inside any garden furniture, trampolines, or other objects that could become projectiles in high winds
• Charge devices and prepare for potential power outages
• Do not travel unless absolutely necessary during a severe storm warning
• If caught outside during a storm, avoid exposed hilltops, standing water, isolated trees, and metallic structures

Lightning Safety

Lightning kills and injures people every year, and the risk is often underestimated because people overestimate their ability to predict when a storm is near. The key rule: if you can hear thunder, you are close enough to be struck by lightning. Seek shelter immediately.

Safe shelter means a substantial building or a hard-topped vehicle with windows closed. Open structures such as bus shelters, canopies, or tents are not safe. Wait at least 30 minutes after the last thunder before returning outdoors.

If caught in the open during a lightning storm with no shelter available: avoid high ground, trees, isolated objects, standing water, and metal fences. Move away from groups and crouch low on the balls of your feet rather than lying flat.

Talking to Children About Extreme Weather

Children who grow up in an era of increasing extreme weather events will be exposed to concerning news, direct experience of weather events, and climate anxiety that can contribute to fear and worry. Addressing this honestly and in an age-appropriate way helps children feel informed and capable rather than overwhelmed.

For young children, keep explanations simple and focus on what the family does to stay safe rather than on broader climate concerns. For older children and teenagers, honest, balanced conversation that acknowledges both the reality of climate change and the genuine efforts being made to address it is more helpful than either minimising the issue or catastrophising.

Involve children in family emergency preparedness activities: assembling the go-bag together, practising what to do in different scenarios, and having a clear family plan for different types of emergency. Children who feel prepared feel more competent and less afraid.

After a Severe Weather Event

After a major weather event, children may need support processing what has happened. Normalise their feelings, answer their questions honestly, and maintain routine as much as possible. Children who have experienced flooding, storm damage to their home, or evacuation have had a genuinely frightening experience and may show signs of stress including sleep difficulties, clinginess, or regression to younger behaviours. These responses are normal and typically resolve with time and support. If they persist or are severe, speak to your family doctor about whether additional support is appropriate.
