Heat index

June's mean heat index is computed to be a sweltering 38°C (100.4°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
