Heat index

Be advised, the heat index considers values for conditions in shade and with a light breeze. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. 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. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
