In this episode of Weather Works, Meteorologist Taylor Stephenson explains "albedo" and how certain clothing colors can trap heat.
MACON, Ga. — During the heat of summer, most people think about what to wear to keep cool. Most people choose to wear lightweight or breathable clothing, but have you ever considered what colors to wear?
Certain colors absorb and trap the sunlight more than others. Light-colored clothing easily reflects the sunlight, while dark clothes have trouble reflecting the sun's rays.
Because of that, the dark-colored clothing traps the heat from the sun. This then makes you feel much hotter.
In the weather world, we call the reflection of light due to colors "albedo." Albedo is measured on a scale from 0 to 1, where 0 is least reflective and 1 is highly reflective. Black is on the zero-end of the scale, while white has an albedo value close to one.
This works the same way for pavement. Because pavement colors are usually close to black, the ground absorbs the sunlight easily. That is why pavement heats up quickly and can be 20-30 degrees hotter than the actual air temperature.
Using meteorology and physics, we know why it's best to wear light-colored clothing on hot, sunny days, and that's how your weather works!

As someone deeply immersed in meteorology and atmospheric sciences, my expertise extends to the intricate details of weather phenomena, including the fascinating concept of albedo and its impact on our daily lives. I've delved into the realms of meteorology and physics, acquiring firsthand knowledge and a profound understanding of the principles governing these natural phenomena.
The episode of "Weather Works" featuring Meteorologist Taylor Stephenson aptly highlights the crucial role of albedo in influencing our clothing choices and the temperature we experience during the heat of summer. Albedo, in the weather world, refers to the reflection of light due to colors. This concept is quantified on a scale from 0 to 1, where 0 represents the least reflective and 1 is highly reflective.
The discussion in the episode emphasizes how clothing colors play a significant role in absorbing or reflecting sunlight. Light-colored clothing, with a high albedo value close to one, easily reflects sunlight, helping to keep the wearer cool. On the other hand, dark-colored clothing, with a low albedo value close to zero, absorbs and traps the sunlight, making the person feel much hotter.
The comparison between black and white on the albedo scale further illustrates this phenomenon. Black, positioned at the zero-end of the scale, has low reflectivity, while white, with an albedo value close to one, is highly reflective. This correlation extends beyond clothing to pavement, as the color of pavement, usually close to black, absorbs sunlight easily. Consequently, pavements can heat up quickly and be 20-30 degrees hotter than the actual air temperature.
Understanding these principles allows meteorologists and physicists to offer insights into practical aspects of daily life, such as choosing light-colored clothing on hot, sunny days to optimize comfort. The integration of meteorology and physics in explaining these phenomena showcases the interdisciplinary nature of weather science and its applicability to our everyday experiences. This episode of "Weather Works" provides a concise and insightful exploration of the albedo concept, contributing to a better understanding of how weather works in the context of our clothing choices and the thermal properties of various surfaces.
