Calculate the Universal Thermal Climate Index using the sliders or using the fields. Use the input to understand the relationship among variables.
Hint: Try to decrease the relative humidity and increase the wind speed simulating a hot day (E.g. in Central Europe).

UTCI (Universal Thermal Climate Index) is an index that express temperature of what the weather "feels like". It takes into account the air temperature, mean radiant temperature, relative humidity, and wind speed in a human energy balance model to give a temperature value that is indicative of the heat stress or cold stress felt by a human body in the outdoors (ref. Ladybug Tools).
