Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers.

Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
