What Temperature Should You Maintain in a Car During Summer?

During the hot summer months, cars can quickly become unbearably warm, making it essential to manage interior temperature efficiently. Whether you’re commuting, traveling, or simply parked, maintaining a safe and comfortable temperature is crucial. Here’s what you need to know.

1. Ideal Cabin Temperature

The optimal temperature range inside your car should be between 22°C and 24°C (71°F–75°F). This ensures comfort without overburdening the vehicle’s air conditioning system.

• Below 21°C: Might feel too cold, especially for children and elderly passengers.
• Above 26°C: Can lead to discomfort, fatigue, and heat-related stress.

2. Best Practices for Using the AC

2.1 Ventilate Before Activating the AC

Open the windows for a few minutes before turning on the air conditioner to release hot air trapped inside.

2.2 Start at Moderate Settings

Do not immediately set the temperature to the lowest. Begin at a moderate setting and adjust gradually.

2.3 Use Air Recirculation Mode

After reaching the desired coolness, activate the recirculation mode to maintain temperature without drawing in hot outside air.

2.4 Direct Vents Correctly

Point air vents upward instead of directly on the body to distribute cool air evenly and avoid chills or stiffness.

3. Never Leave Children or Pets Inside

Under no circumstance should a child or animal be left alone in a parked car, even for a few minutes. Temperatures can soar dangerously fast and lead to fatal consequences.

4. Maintain the Air Conditioning System

Regular AC maintenance ensures efficiency and good air quality:

• Have your system checked at least once a year.
• Replace the cabin air filter regularly to avoid dust and allergens.

5. AC or Open Windows?

Choose based on driving conditions:

• In the city: Opening windows at low speeds is often sufficient.
• On highways: Prefer the AC to reduce wind resistance and noise.

6. Summary Table

Condition	Recommended Temperature
Optimal Comfort	22°C to 24°C
Too Cold	< 21°C
Too Hot	> 26°C

By following these simple but vital tips, you ensure a safe, healthy, and comfortable ride throughout the hottest months of the year.
