Go with the (air) flow - Top tips to reduce condensation inside your tent

Even the most seasoned campers can wake up to an unexpectedly damp interior. But in most cases, it’s not rain sneaking in—it’s condensation, caused by you and the ground beneath your tent!

Tiny droplets can gather along seam lines, dot the roof, and find their way into windows, toggles, and zips. Even if there’s no rain in sight, warm, humid air inside the tent (from people, heating, damp gear, and poor ventilation) hits the cooler tent fabric, turning moisture vapour into liquid. It’s the same process that causes condensation on a cold house window when the heater is cranked up inside—it’s just physics.

Condensation tends to be worse when there’s a big temperature difference between day and night, particularly after a warm, humid day. Those classic Aussie conditions—hot days followed by cool nights—can make managing condensation a challenge.

Even with a high-quality, virtually waterproof tent like the Domex Ascent, condensation management is still up to you. Here’s how to keep things dry inside:

1. Vent your tent

Airflow is key to reducing moisture build-up. Domex tents are designed with ventilation in mind—wide-opening doors encourage cross-breeze, and mesh side vents let air circulate while keeping mozzies and sandflies at bay.

2. Pick your campsite wisely

Choose a dry, well-ventilated spot to set up camp. Avoid pitching your tent too close to large rocks, dense bush, or other natural barriers that could block airflow. Low-lying areas like valleys, lakesides, and riverbanks tend to hold more moisture, increasing the risk of condensation.

3. Cook outside

Apart from the obvious fire safety risks, cooking inside your tent produces steam, adding to moisture levels. Always cook outdoors under a tarp or awning for a safe, dry, and comfortable setup.

4. Keep wet gear outside

Damp clothing and gear contribute to indoor humidity. If possible, store wet items outside. If the weather isn’t cooperating, stash them in the vestibule and keep the main tent zipped up.

5. Wipe it down

Even with the best prevention strategies, some condensation is inevitable. A quick wipe with a microfibre towel will absorb excess moisture without taking up much space in your pack. Just remember to air it out after use.

With a Domex tent to shield you from the elements and these simple tricks, you’ll stay dry, comfortable, and ready for adventure.
