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.

Governing equation

T_{w c} = 13.12 + 0.6215 (- 5) - 11.37 (30)^{0.16} + 0.3965 (- 5) (30)^{0.16} = - 13.0^{\circ} C

Reading this result: At 30 km/h the wind strips 8 °C off the air temperature, so exposed skin feels like -13 °C.
