Heat index

In reference to the heat index, it's for places in shade and with a slight wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
