The thermometer only tells half the story. In the cold, wind strips away the thin warm layer around your skin, making it feel far colder — wind chill. In the heat, humidity blocks sweat from evaporating, making it feel hotter — the heat index. Both estimate the apparent temperature your body actually experiences.
