Heat index

The heat index value during July is evaluated at 29°C (84.2°F). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.
The heat index's values are generally associated with conditions in shade and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
