Heat index

July's average heat index is calculated to be a blistering 41°C (105.8°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
