The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

What wet bulb globe temperature tells you about the weather In hot temperatures, the human body typically creates sweat as a way to control body temperature through evaporative cooling.
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
On August 28, 2024, a weather station in southern Iran recorded a heat index of 82.2 °C (180.0 °F), which will be a new record if confirmed. [9] The human body requires evaporative cooling to prevent overheating. Wet-bulb temperature and Wet Bulb Globe Temperature are used to

Research led by Queen's University Belfast used 20 years of meteorological data to show how hot the host stadiums get during an average summer, using a 'wet bulb globe temperature' (WBGT) - which ...
The wet-bulb globe temperature (WBGT) combines the effects of radiation (typically sunlight), humidity, temperature and wind speed on the perception of temperature.
‘Wet-bulb temperature’ refers to temperatures taken with a thermometer covered in a wet cloth, which are normally slightly cooler than ‘dry-bulb’ temperatures.
