Heatwave Readiness in Australia: Tips to Stay Prepared

Heatwaves are a familiar part of Australian summers — but they affect more than just how hot the day feels. Extended periods of extreme heat can impact air quality, wildlife behaviour, pests in and around the home, hydration levels, and even skin health, often all at once.

During heatwaves, risks tend to build quietly. Bushfire smoke can travel far from fire zones, snakes and insects become more active as they search for water, food waste breaks down faster, and dehydration or skin irritation can set in before you realise it. These aren’t reasons to panic — but they are reasons to be prepared.

This guide looks at some of the key things to be mindful of during Australian heatwaves, and shares practical ways to stay comfortable, safe and organised at home and outdoors when temperatures rise.

Why heatwaves are becoming more common in Australia

Heatwaves are not just a seasonal inconvenience — they’re becoming more frequent, more intense and longer-lasting across Australia. This shift is closely linked to rising average temperatures, which are increasing the likelihood of extreme heat events year after year.

Climate data from the Australian Climate Service shows that Australia is already experiencing more hot days and hotter extremes, and this trend is expected to continue. It’s projected that Australia will experience more than double the number of severe or extreme heatwave days each year, on average, with inland and northern regions facing the greatest change.

Research also indicates that the hottest day of the year is getting hotter, not just the average summer day. Even small increases in average temperatures can significantly increase the number of days where heat reaches levels that impact health, infrastructure and the environment. With additional extreme heatwave days each year, it will place greater strain on households, communities and emergency services.

The effects won’t be felt evenly. In New South Wales, climate modelling suggests that by 2070, the number of heatwaves could increase by around 2.5 to 4.5 events per year, with even greater increases expected in central and northern parts of the state. Some regions — particularly inland areas and parts of the Great Dividing Range — are expected to see larger increases in extreme heat, while coastal areas and regions such as Tasmania may experience smaller changes. However, no part of Australia is immune to the overall trend.

What heatwaves affect — and what to be mindful of

As heatwaves become more frequent and intense, their impact goes well beyond higher temperatures. Extended periods of extreme heat can quietly influence air quality, wildlife behaviour, household hygiene, hydration levels and skin health, often all at once.

Many of these effects aren’t immediately obvious — they build over days of sustained heat and can catch people off guard if they’re not prepared. Being mindful of these changes helps you take simple, practical steps to stay comfortable and reduce risk at home, outdoors and while travelling.

Below are some of the key areas to be aware of during heatwaves.

1. Bushfires, smoke and air quality

Heatwaves significantly increase the risk of bushfires, particularly during prolonged dry periods. Even if fires are burning hundreds of kilometres away, smoke can travel long distances, affecting air quality well beyond fire zones. This can lead to hazy skies, strong smoke odours and irritation of the eyes, nose and throat.

Poor air quality during heatwaves can affect everyone, but it’s especially uncomfortable for people with asthma, respiratory conditions, heart disease, older adults and young children. Smoke particles are often very fine, meaning they can be inhaled deep into the lungs without being obvious.

During smoky conditions, it’s important to:

• Limit outdoor activity when air quality is poor
  

• Keep windows and doors closed where possible
  

• Be mindful of indoor air quality, especially during multi-day heat events

Having protective masks on hand can be particularly helpful during smoky conditions, but not all masks provide the same level of protection. Bushfire smoke contains very fine particles, often referred to as PM2.5, which are 2.5 microns or smaller and can penetrate deep into the lungs.

Masks designed for higher filtration — such as P2 or N95 respirators — are made to filter out at least 94–95% of these fine airborne particles when properly fitted. This makes them far more effective for smoke exposure than standard surgical or cloth masks, which are primarily designed to block larger droplets rather than fine particulate matter.

Using a well-fitted P2 or N95 mask during periods of heavy smoke can help reduce inhalation of these tiny particles, especially when outdoor exposure can’t be avoided or when smoke lingers over several days. Keeping a small supply on hand before heatwave and bushfire season begins makes it easier to respond quickly when air quality deteriorates.

It’s also helpful to check local air quality levels, especially during heatwaves and bushfire season, as smoke conditions can change quickly throughout the day. Air quality is often reported using an Air Quality Index (AQI), which indicates how clean or polluted the air is and whether it’s safe to spend time outdoors.

In Australia, you can monitor real-time air quality and smoke conditions by location using tools such as IQAir’s Australia air quality map.

2. Wildlife and pest activity

Heatwaves don’t just affect people — they also change the behaviour of wildlife and pests. As temperatures rise and natural water sources dry up, animals and insects are more likely to move closer to homes, gardens and built-up areas in search of shade, water and food.

Increased wildlife activity

During extreme heat, wildlife such as snakes, lizards and rodents may become more visible around backyards, sheds, garages and pools. Snakes, in particular, are more active in hot weather and may seek cooler, sheltered spaces near homes or water sources. This doesn’t mean wildlife is becoming aggressive — it’s usually a response to environmental stress.

Being mindful during heatwaves means:

• Keeping yards tidy and free of clutter where animals can shelter, such as piles of timber, garden waste or unused equipment
  

• Checking around outdoor areas before gardening or using sheds, garages or storage spaces
  

• Being extra cautious near water sources, such as pools, ponds or bird baths, where wildlife may gather during extreme heat
  

• Having a snakebite first aid kit readily accessible, especially if you live in areas where snakes are known to be present, so you’re prepared in the unlikely event of a bite

Pests activity

Heatwaves also create ideal conditions for insects and household pests. Prolonged heat can also increase the activity and spread of insects that act as disease carriers. Research published in Hygiene and Environmental Health Advances shows that extreme heat creates environments that support the survival and faster reproduction of many microorganisms, while also expanding the range and activity of insect vectors such as mosquitoes, flies and cockroaches. 

As temperatures rise, these insects become more active, reproduce more quickly and are more likely to come into contact with people, especially when heat causes food waste to break down faster, producing stronger odours that attract pests  into homes and outdoor areas.

Common heatwave-related pest issues include:

• Mosquitoes, which breed more rapidly in warm, stagnant water
  

• Flies, which are drawn to food waste and bins
  

• Ants and cockroaches, which seek moisture and cooler indoor spaces

Good hygiene becomes especially important during extreme heat. Regularly emptying bins, sealing food waste properly, reducing standing water, and using appropriate pest-control measures can help reduce unwanted activity during prolonged hot spells.

3. Hydration

During heatwaves, staying hydrated is essential — but hydration goes beyond simply drinking more water. Extreme heat causes the body to lose fluids and electrolytes more quickly through sweat, and dehydration can occur before you feel thirsty, especially during prolonged hot spells.

In hot conditions, people often underestimate how much fluid they’re losing, particularly when spending time outdoors, exercising, gardening or travelling. Dehydration can lead to symptoms such as fatigue, headaches, dizziness and reduced concentration, which may increase the risk of heat-related illness if not addressed early.

Hydration also plays an important role in skin health during heatwaves. Increased sweating, sun exposure and frequent washing can leave skin feeling dry, irritated or sensitive. Heat and moisture can also contribute to heat rash and chafing, particularly in areas where skin rubs together, such as thighs, underarms and around swimwear. These issues are common during summer, especially after swimming, beach days or long periods of physical activity.

Preventing skin irritation is often much easier than treating it once it develops. Keeping skin clean and dry, using gentle, skin-friendly washes, and applying protective products before irritation starts can help maintain the skin’s natural barrier during hot weather.

Barrier creams can help reduce friction and protect skin from moisture-related irritation, while mild cleansers are better suited to frequent use without stripping the skin of its natural oils.

4. Sun exposure and skin protection

Heatwaves often mean longer periods outdoors, stronger UV exposure and higher risk of sunburn — even on days that don’t feel excessively sunny. During extreme heat, UV levels can remain high from morning through late afternoon, increasing the strain on skin and raising the risk of both short-term damage and long-term skin health issues.

Using a broad-spectrum sunscreen is one of the most important protective steps during heatwaves. Sunscreen helps shield the skin from UVA and UVB rays, reducing the risk of sunburn, heat-related skin irritation and cumulative sun damage. This is especially important for children, older adults, outdoor workers and anyone spending extended time outside.

Being mindful during heatwaves means:

• Applying sunscreen generously to exposed skin
  

• Reapplying regularly, especially after sweating or swimming
  

• Pairing sunscreen with protective clothing, hats and shade where possible

Staying prepared during the Australian heatwave

Heatwaves are becoming a more regular part of Australian summers, and their effects extend well beyond hot days alone. From air quality and bushfire smoke to increased wildlife and pest activity, dehydration and skin irritation, prolonged heat can quietly impact comfort, health and safety if you’re not prepared.

The good news is that small, practical steps make a meaningful difference. Being mindful of changing conditions, staying hydrated, managing indoor air quality, maintaining good hygiene, and taking simple preventative measures can help reduce risk and make heatwaves easier to manage.

With a little forward planning and the right essentials on hand, it’s possible to stay comfortable, safe and well during periods of extreme heat — allowing you to focus on enjoying summer rather than just getting through it.
