Temperature vs. Humidity: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on December 16, 2023
Temperature measures the degree of heat, indicating how hot or cold something is, while humidity refers to the amount of water vapor in the air.

Key Differences

Temperature is a physical quantity expressing the degree of heat or cold in an environment, measured in degrees (Celsius, Fahrenheit). Humidity, on the other hand, measures the concentration of water vapor present in the air, expressed as a percentage.
High temperatures can affect the comfort level, physical health, and energy usage, whereas high humidity levels can cause discomfort, mold growth, and affect health.
Temperature is sensed by the human body through skin and perceived as heat or cold. Humidity is felt as the degree of moisture in the air and influences how we perceive temperature.
Thermometers are used to measure temperature, utilizing materials that expand or contract with heat. Hygrometers measure humidity, assessing the moisture content of the air.
Temperature significantly influences weather patterns and climate zones, whereas humidity plays a critical role in precipitation, cloud formation, and overall climate.

Temperature and Humidity Definitions


A measure of the degree of heat in an environment.
The temperature today reached 30 degrees Celsius.


The concentration of water vapor present in the air.
The humidity level today is unusually high.


An indicator of the kinetic energy of particles in a substance.
The temperature of boiling water is 100 degrees Celsius.


A key factor in determining the comfort level of an environment.
High humidity makes the heat feel more oppressive.


A variable controlled in various scientific experiments.
We maintained a constant temperature in the incubator.


Measured as a percentage of moisture in the air.
The humidity in the rainforest can reach 90%.


A factor determining the state of matter (solid, liquid, gas).
The temperature drop caused the water to freeze.


Influential in weather patterns and precipitation.
Increased humidity often precedes rainfall.


A critical parameter in weather forecasting.
The temperature is expected to rise this weekend.


A variable affecting indoor air quality.
We use a dehumidifier to reduce humidity in the basement.


The degree of hotness or coldness of a body or environment.


Dampness, especially of the air.


A measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale.


Relative humidity.


Dampness, especially that of the air.


The amount of water vapour in the air.


Moisture; dampness; a moderate degree of wetness, which is perceptible to the eye or touch; - used especially of the atmosphere, or of anything which has absorbed moisture from the atmosphere, as clothing.


The content of water vapor in the air, expressed as a percent of the maximum amount of water vapor that the air can hold at the given temperature; also called relative humidity. The capacity of the air to hold moisture increases with temperature, so if the temperature changes without changing the absolute content of the atmospheric moisture, the relative humidity will also change.
