Heat index

The heat index value for April is appraised at an extremely hot 42°C (107.6°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
