What Is Wind Chill?

Wind chill describes how cold it feels on exposed skin when wind removes heat from the body faster than still air. It is not a separate measurement of air temperature; it combines temperature and wind to help communicate cold-weather exposure risk.

Why wind makes cold feel colder

Heat loss increases

A layer of warm air naturally forms near skin and clothing. Wind disrupts this layer, allowing heat to escape more quickly.

Exposed skin matters

The face, ears, fingers, and other uncovered areas can cool quickly in cold and windy conditions.

Wet conditions add risk

Rain, sweat, and damp clothing can increase heat loss. Staying dry is an important part of cold-weather preparation.

How to reduce exposure

Layer clothing

Wear several layers, including a wind-resistant outer layer, and cover hands, ears, and face when needed.

Limit time outdoors

Take warming breaks in a sheltered place and check children, older adults, and people who may be more vulnerable to cold.

Know warning signs

Numbness, unusual confusion, clumsiness, or persistent shivering can be serious. Move to warmth and seek medical help when needed.

Use the official local wind-chill guidance for decisions during cold-weather alerts. This article is general information, not a medical diagnosis.
