Heat index

June's heat index is evaluated at a sweltering 96.8°F (36°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
