You feel colder on a windy day due to a phenomenon called wind chill. Wind increases the rate of heat loss from your body by carrying away the warm air that forms a thin insulating layer around your skin. This enhanced evaporation of moisture from your skin also contributes to the sensation of cold, making it feel significantly colder than the actual air temperature. As a result, the combination of wind and lower temperatures can make you feel much chillier.
