Condensation in Tents and Awnings

Mar 16, 2023

Don't fret if you find water in your tent; it's unlikely to be a leak. All of our tents use quality materials and sealed seams to keep the weather out, ensuring a dry and cozy camping experience.


Condensation in a tent or awnings occurs when water in the air inside the tent comes into contact with a colder surface, such as the tent walls or the ceiling, and condenses into liquid. This can happen when the outside temperature is cooler than the inside temperature of the tent, or when there is high humidity inside the tent.

Condensation can be particularly common in tents because they often have limited ventilation, which can trap moist air inside. It can also be more of an issue in colder weather when the temperature difference between the inside and outside of the tent is greater.

Condensation in a tent can lead to dampness inside the tent, which can make it uncomfortable to sleep in and can also cause damage to equipment or clothing. To reduce the amount of condensation in a tent, it's important to ensure proper ventilation, such as by opening windows or vents, and avoiding activities that generate a lot of moisture, such as cooking or boiling water inside the tent.

It's important to note that tents are designed to be highly waterproof, so if you do encounter water inside your tent, chances are it's not actually leaking. Rather, it's likely just condensation that's accumulated overnight.

Signs of condensation

  • Water droplets on the inside of the tent
  • Damp or wet sleeping bags, clothing, or gear
  • A musty or damp odour inside the tent
  • Visible moisture or fog inside the tent
  • A layer of moisture on the tent walls or roof
  • Beading or droplets of moisture on the interior of the tent

Signs of a leaking tent

  1. Water consistently pooling in the same points
  2. Heavy water ingress in one location
  3. Darker patches of canvas on wall and roof

Polyester Tents and Condensation

Polyester is a non-breathable fabric that becomes even more resistant to moisture once treated with waterproofing. This means that without proper ventilation, condensation can build up inside the tent, leaving you with a damp and uncomfortable camping experience.

To combat this, it's essential to keep the ventilation points in your polyester tent open at all times. This will allow fresh air to circulate throughout the tent, preventing the build-up of moisture. For even better ventilation, consider leaving the mesh doors open to promote airflow and breathability.

Condensation in Air Tents

Air tents are more prone to condensation compared to pole tents due to their internal Airbeams. The difference in temperature between the air inside the beam and the outside air can cause condensation to form at night. This often leads to pooling at the base of the beams or damp rising up the beams, which is usually a result of condensation, especially if it's present on all beams.

How to stop condensation in Tents & Awnings

Condensation is common in tents, especially in humid or rainy conditions. The best way to reduce condensation is to make sure your tent is well ventilated. Proper ventilation is key to reducing condensation. Open all vents and doors, even if the weather is cool or rainy, to promote airflow and prevent moisture from accumulating inside the tent. If your tent has mesh windows or doors, use them to provide additional ventilation while keeping insects out.
