Estimated Container Temperatures

Overview

Shipping containers are made from steel, which makes them susceptible to temperature fluctuations. The internal temperature of a shipping container can be higher than the outside air temperature, particularly when exposed to direct sunlight. This article provides insights into how external conditions affect container temperatures.

This is to be used as a rough guide, as many factors can affect the temperature inside.

Temperature Guide

The table below provides an estimated relationship between outside air temperature and the internal temperature of a shipping container.

Outside Air Temperature (°C)	Uninsulated Container Internal Temperature (°C)
-5°C	-5–0°C
0°C	0–5°C
10°C	15–25°C
20°C	30–45°C
25°C	35–50°C
30°C	45–60°C
35°C	50–65°C
40°C	55–70°C

Key Factors Affecting Internal Temperature

• Direct Sunlight: Containers in direct sunlight will absorb more heat, increasing internal temperatures significantly.

• Ventilation: Proper ventilation can help regulate airflow and lower peak internal temperatures.

• Insulation: Insulated containers maintain a more stable internal climate, reducing extreme temperature fluctuations.

• Container Color: Darker containers absorb more heat, while lighter-colored containers reflect some solar radiation, keeping them cooler.

• Humidity and Airflow: Humid conditions can exacerbate heat retention inside the container.
