Heat index

June's mean heat index is computed to be a burning hot 47°C (116.6°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
