Marquees and tents are a popular choice for events, retail activations, and corporate functions, but in hot weather, they can quickly become uncomfortable if not cooled correctly. So how does one cool a marquee or tent?
One of the biggest misconceptions we see is the assumption that air conditioning is the answer. In reality, traditional air conditioning is rarely practical or effective in temporary structures.
Based on our hands-on experience at Chill Out | Air Cooler Rentals, here’s what actually works when it comes to cooling marquees and tents in hot conditions.
Why Air Conditioning Doesn’t Work in Marquees
Air conditioning systems are designed for sealed environments. Marquees and tents are the opposite.
Common issues include:
- Open or partially open sides
- Constant air leakage
- High heat gain from direct sunlight
- Extremely high power requirements
❗️ Even when an AC unit is used, cooled air escapes faster than it can be replaced, making the system inefficient and costly.
What Does Work: Evaporative Air Coolers
Evaporative air coolers are specifically suited to temporary and semi-open structures.
They work by:
- Drawing in hot air
- Passing it through water-saturated cooling pads
- Delivering a continuous flow of cooled, fresh air
👍 Because they don’t rely on sealed spaces, they are far more effective in marquees and tents.
Key Factors When Cooling a Marquee or Tent
1. Size of the Structure
- Larger marquees require multiple cooling points to ensure even airflow.
2. Open vs Closed Sides
- Open-sided marquees need additional cooling capacity due to air loss.
3. Orientation & Sun Exposure
- Marquees positioned in direct sunlight heat up faster, especially during midday and afternoon events.
4. Number of Guests
- Crowds generate heat, particularly on dance floors and near stages or bars.
5. Power & Water Access
- Reliable power and nearby water access are essential for sustained evaporative cooling.
Correct Air Cooler Placement (This Matters)
Placement is just as important as quantity.
Best practices include:
- Positioning coolers at entry points or open sides
- Directing airflow across the length of the marquee
- Avoiding obstacles such as walls, décor, or staging
- Creating cross-ventilation where possible
❗️ Poor placement can reduce effectiveness even with enough units on site.
How Many Air Coolers Does a Marquee Usually Need?
There’s no universal answer, but practical guidelines help.
As a starting point:
- Medium-size Evaporative Air Coolers typically cover 35–40 m²
- Large-size Evaporative Air Coolers typically cover 50–70 m²
Open-sided marquees generally require 20–30% more cooling capacity.

Common Mistakes When Cooling Marquees
Relying on Fans Alone
- Fans move hot air around but don’t reduce temperature.
Using Misting Fans in Enclosed Areas
- Mist increases humidity and can make conditions uncomfortable.
Underestimating Heat Build-Up
- Marquees heat up quickly, especially with crowds and direct sun exposure.
