How to Prevent Condensation in Your Motorhome
Condensation can be an annoying issue when traveling in a motorhome or campervan. Waking up to foggy windows, damp bedding is never ideal, and preventing moisture buildup is crucial for comfort and vehicle longevity. However, Australia’s varied climates—from the humid tropics of Queensland to the cooler, misty mornings in Tasmania—mean different strategies work best depending on where you’re traveling.
1. Understanding Motorhome Condensation
Condensation occurs when warm, moist air comes into contact with a cold surface, such as windows, walls, or even cupboards in your motorhome. Everyday activities like cooking, showering, and even breathing contribute to moisture buildup. If not managed properly, condensation can lead to mould, mildew, and damage to your motorhome’s interior.

2. Tips for Preventing Condensation Based on Australian Regions
Queensland & Northern Australia (Hot & Humid Climates)
In Queensland, the Northern Territory, and tropical parts of Western Australia, high humidity levels mean that moisture is always in the air, making condensation more likely, especially when using air conditioning inside your motorhome.
Our Tips:
- Maximise Ventilation: Always keep windows and roof vents open whenever possible to allow moist air to escape.
- Use a Dehumidifier or Moisture Absorbers: A small rechargeable dehumidifier or moisture-absorbing crystals (like DampRid) can help reduce indoor humidity levels.
- Air Out Bedding Daily: Humid conditions can make mattresses and bedding feel damp. Leave windows open and air out your bedding daily to prevent moisture buildup.
- Cook Outdoors When Possible: Cooking produces steam, which can quickly lead to condensation. Using an outdoor BBQ or portable stove helps keep excess moisture outside. Most caravan parks have BBQ to use. Alternatively, keep windows open while cooking inside your motorhome.

Victoria, Tasmania & Southern Australia (Cooler & Wet Climates)
In Tasmania, Victoria, and southern parts of South Australia, condensation is more common in winter when cold temperatures outside meet warm air inside the motorhome. Misty mornings and frequent rain can also make keeping things dry a challenge.
Our Tips:
- Use Insulated Window Covers: Reflective or insulated window covers help maintain an even interior temperature, reducing condensation buildup overnight.
- Keep Heating Ventilated: If using the heater, ensure there’s proper airflow to prevent excess moisture from accumulating in enclosed spaces.
- Dry Wet Gear Outside: Raincoats, umbrellas, and wet shoes should be left in an awning or covered outdoor area rather than inside your motorhome.
- Wipe Down Surfaces Daily: In colder climates, condensation often forms overnight. Keep a microfiber cloth handy to wipe windows and walls dry in the morning.

New South Wales & South-East Queensland (Mild & Variable Climates)
New South Wales and southeastern Queensland experience a mix of humid and dry conditions depending on the season. Coastal areas can be more humid, while inland regions are drier.
Our Tips:
- Use Cross-Ventilation: Open windows on opposite sides of the motorhome to create airflow and reduce humidity inside.
- Monitor Weather Changes: If you’re expecting a cool night after a warm day, prepare by keeping vents open slightly to balance temperature changes.
- Avoid Drying Clothes Inside: When staying at a powered campsite, take advantage of laundry facilities rather than hanging damp clothes inside your vehicle.

Western & Central Australia (Hot & Arid Climates)
Western Australia and central Australia (the Outback) have low humidity levels, but temperature fluctuations between day and night can still cause condensation inside motorhomes.
Tips:
- Park Strategically: If possible, park in a shaded area during the day to avoid excessive heat buildup, which can lead to condensation when temperatures drop at night.
- Keep Vents Open at Night: Even though nights can be cool, keeping a small vent open will help balance temperature differences and prevent moisture buildup.
- Avoid Overusing Air Conditioning: Blasting cold air inside your motorhome and then stepping into hot outdoor air can lead to condensation forming inside when you return.

3. General Tips to Reduce Condensation in Any State
Regardless of where you’re travelling, these simple habits will help keep moisture levels low in your motorhome:
- Open Fans While Cooking & Showering: Keep windows open during the day to increase airflow while cooking and showering. Use the exhaust fan above the kitchen stove (Avida Motorhomes).
- Keep Air Circulating: If you’re parked up for the night, crack a window open slightly to keep fresh air moving.
- Choose Breathable Materials: Opt for cotton bedding and seat covers instead of synthetic fabrics, which can trap moisture.
- Check Seals & Insulation: Make sure your motorhome is well-sealed but still allows airflow. Sealing gaps improperly can trap moisture inside.
- Invest in a Small Portable Fan: A battery-operated or USB fan can help keep air moving and prevent stagnant, damp areas inside.
- Wipe Down Surfaces: Regularly wipe down surfaces, especially windows and walls, to remove any visible condensation before it has a chance to settle and cause damage.
- Protect Mattresses: Consider using waterproof mattress covers to protect mattresses from moisture damage.
- Windscreen & Window Covers: In winter, a windscreen cover can help keep the motorhome warmer and reduce condensation.
Managing condensation in your motorhome or campervan is all about understanding the climate you’re traveling in and adjusting your habits accordingly. Whether you’re exploring the humid tropics of Queensland, the cool highlands of Tasmania, or the dry expanses of the Outback, these simple strategies will help keep your motorhome comfortable and free from excess moisture.
