Wind Chill Index

The Wind Chill Index measures how cold it feels outside when wind is factored in, compared to still air at the same temperature. Wind increases heat loss from your body, making you feel colder than the actual temperature. For example, if the temperature is 30°F with strong wind, it may feel like 20°F. This index helps people understand potential risks of frostbite or hypothermia and guides appropriate clothing and outdoor activity decisions during cold, windy conditions.
