Understanding 'Feels-Like' Temperature: A Comprehensive Guide

The "feels-like" temperature, also known as the apparent temperature, represents how the human body perceives the combination of air temperature, humidity, and wind speed. Unlike the actual air temperature, the feels-like temperature accounts for environmental factors that influence our comfort levels.

What Is the 'Feels-Like' Temperature?

The feels-like temperature is a calculated value that combines air temperature with other environmental factors to estimate how hot or cold it feels to the human body. This metric is particularly useful because it provides a more accurate representation of human comfort than the actual air temperature alone.

How Is the 'Feels-Like' Temperature Calculated?

The calculation of the feels-like temperature varies depending on the prevailing weather conditions:

• In Cold Conditions (Wind Chill):

When temperatures are low and wind speeds are high, the wind accelerates heat loss from the body, making it feel colder than the actual air temperature. The National Weather Service (NWS) provides a formula to calculate wind chill:

Wind Chill (°F) = 35.74 + 0.6215T - 35.75(V^0.16) + 0.4275T(V^0.16)

Where:

• T is the air temperature in degrees Fahrenheit.

• V is the wind speed in miles per hour.

This formula is applicable when the air temperature is 50°F or lower, and the wind speed is 3 mph or higher. (climate.umt.edu)

• In Warm Conditions (Heat Index):

In hot and humid conditions, the body's ability to cool itself through sweating is impaired, making it feel hotter than the actual air temperature. The NWS uses the following formula to calculate the heat index:

HI = -42.379 + 2.04901523*T + 10.14333127*RH - 0.22475541*T*RH - 0.00683783*T^2 - 0.05481717*RH^2 + 0.00122874*T^2*RH + 0.00085282*T*RH^2 - 0.00000199*T^2*RH^2

Where:

• T is the air temperature in degrees Fahrenheit.

• RH is the relative humidity as a percentage.

This formula is used when the air temperature is 80°F or higher, and the relative humidity is 40% or higher. (climate.umt.edu)

Why Is the 'Feels-Like' Temperature Important?

Understanding the feels-like temperature is crucial for several reasons:

• Health and Safety:

Extreme wind chills can lead to frostbite and hypothermia, while high heat indices can cause heat exhaustion and heat stroke. Being aware of the feels-like temperature helps in taking appropriate precautions.

• Comfort:

It aids in dressing appropriately for the weather, ensuring comfort during outdoor activities.

• Planning Activities:

Knowing the feels-like temperature helps in scheduling outdoor events and activities, as it provides a more accurate measure of the conditions.
