Heat index

April's mean heat index is computed to be a burning hot 52°C (125.6°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
