4 Tips On How to Keep Your Caravan Cool In Summer 2026

The Aussie summer is in full swing. And while a road trip is always a good idea, nobody enjoys sitting in a caravan that heats up fast in the sun. At Carac, we know that keeping your van cool is about more than comfort. It is about safety and being able to relax properly at the end of the day and actually enjoy your time away.

Whether you are parked up at a beachside holiday park or heading off-grid, keeping temperatures under control makes a big difference. Here is our practical guide to beating the heat this summer.

1. External Shade: Your First Line of Defence

One of the most effective ways to stay cool is to stop heat before it enters your caravan. Anyone who has parked up with the afternoon sun hitting the side of the van knows how quickly temperatures can climb.

Direct sunlight on walls, windows and vents puts extra strain on your fans and air conditioning. Good external shade not only blocks the sun, it also helps your fridge work more efficiently and makes your living space far more comfortable, both inside the van and outside under the awning.

Why External Shade Makes a Difference

1.    Blocks direct sunlight before it reaches the caravan
2.    Helps reduce interior heat and supports fridge performance 
3.    Creates a usable shaded area throughout the day

Awnings, Privacy Screens and End Drops

An awning forms the base of a good shade setup, covering the side of your caravan and protecting key areas such as the fridge vent and entryway. Adding privacy screens or end drops gives extra protection from low sun while still allowing airflow, so heat does not get trapped underneath.

Not sure what size awning you need? We previously shared a step-by-step guide on how to measure your caravan awning correctly.

Recommended Shade Solutions

• Supex Caravan Awning Porch Extension. Adds extra shaded space and helps keep direct sun off fridge vents and entryways, reducing heat coming into the van.
• CGear End Drop With Zipper Door. Designed for Australian conditions, this screen blocks up to 90 percent of UV rays while maintaining airflow. Ideal for blocking low afternoon sun, reducing heat and adding privacy without creating a heat trap.
• CGear Privacy Screen 6.6 ft x 16 ft Longer Drop. A larger side screen that provides effective shade and wind protection. By covering a wider area, it helps keep your campsite cooler and reduces sun glare inside the van.

2. Efficient Airflow: The Role of Cooling Fans

While shade does the hard work outside, airflow inside the caravan is just as important. On warm evenings, moving air can make the difference between a restless night and a good sleep. Good ventilation helps prevent warm, stagnant air building up, especially overnight. At Carac, we have a large range of cooling fans available.

12V and 24V DC Fans

When camping off-grid, fans that move plenty of air without draining your battery are essential. Most caravan-specific fans run on 12V or 24V DC power, offering low power draw and quiet operation. That makes them ideal for use overnight and while being offgrid.

Portable and Rechargeable Fans

Portable fans are a great addition to fixed fans. They can be used in sleeping areas, under the awning or even in the car. USB recharging makes them easy to keep running while travelling.

What to look for in a good fan

1.    Low amp draw to help preserve battery life off-grid
2.    Quiet operation for a better night’s sleep
3.    Adjustable or gimbal design to direct airflow where it’s needed

• Sirocco II 12V and 24V Fan. A popular choice thanks to its gimbal design and three speed settings, allowing you to aim airflow exactly where you want it while using minimal power. Available in white and black.
• NCE 12V Oscillating Fan with Light. A compact fan that oscillates to spread airflow through bunk areas and shared spaces, with a built-in light that is handy at night.

• Explore 12V Twin Fan. With two adjustable fan heads and a secure suction base, this fan delivers airflow across a wider area. Ideal for larger spaces or when extra ventilation is needed during hot conditions.
• RV White 12V Fan & White Fast Charger Combo. A practical and compact 12V fan that combines airflow with fast charging. Ideal for keeping cool overnight while also charging your devices, making it a handy option for smaller spaces or bedsides in the van.

3. Maximum Cooling: Caravan Air Conditioning

As temperatures climb, airflow alone is not always enough. On really hot days, there’s nothing better than stepping into a cool van at the end of the afternoon. A dedicated caravan air conditioning unit removes heat and humidity, delivering a level of comfort that fans simply cannot match.

Most units run on 240V mains power and are ideal for powered sites. With modern battery systems and inverters, some travellers are also able to run air conditioning for limited periods while off-grid.

Choosing the Right Unit

1. Rooftop Units: These save internal storage space and are highly effective at circulating cool air throughout the van. A popular choice for caravans that spend time on powered sites.
2. Under-Bunk Units: A great solution for pop-tops or for those wanting to keep a lower vehicle profile. Ideal when rooftop installation is not practical or preferred.

Recommended Air Conditioning Solutions

1. Dometic FreshJet RV Air Conditioner 7 Series Pro. A rooftop air conditioner designed for hot conditions, delivering strong cooling performance while maintaining efficient airflow for comfortable interior temperatures.
2. Finch Australia Houghton 3400 Air Conditioner Roof Top. A powerful rooftop unit suited to larger caravans, providing high capacity cooling to quickly reduce interior heat on very hot days.
3. Truma Saphir Reverse Cycle Air Conditioner Kit (Under Bunk). A compact under bunk solution that keeps the centre of gravity low while delivering reliable cooling where rooftop installation is not preferred. This is a popular choice for those specialising in off-road travel.

A powerful under-bunk air conditioner with inverter technology, offering efficient cooling and heating while keeping rooftop space clear. A great option for caravans where roof installation is not preferred, without compromising on performance.

4. Portable Ice Cube Makers

Nothing beats a cold drink during a heatwave, but caravan freezers can struggle in extreme heat. A portable ice cube maker takes the pressure off your main fridge and ensures you always have ice on hand.

From our experience, reducing the frequency of opening your main fridge door is the single best thing you can do for your battery system during a heatwave. These compact units produce fresh ice in as little as 10 to 15 minutes, making them a practical comfort upgrade for hot days on the road without relying on buying bags of ice at every stop.

Key Benefits

• Produces fresh ice quickly to keep drinks cold in hot conditions
• Helps reduce load on your caravan fridge in extreme heat
• Suitable for use with an appropriately sized inverter
