Throughout May, the heat index is calculated to be a hot 89.6°F (32°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Realize that the values for the heat index are set for shaded places and light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for 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.
