Average Skin Temperature: Factors & Variations

The average surface temperature of human skin is around 33 °C, or 91.4 °F.

- Skin temperature can vary depending on age, gender, physical activity, time of day, and other factors.

-For example, the skin temperature of a young, healthy adult male during moderate exercise typically increases to around 38 °C or 100°F.

-Skin temperature also shows circadian variation as part of human circadian physiology, being 1–2 °C (2–4 °F) warmer during active daytime hours due to increased physical activity than during quiet daytime hours and nighttime.
