Note that heat index values are valued for light wind and location in the shade. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. 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 of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Note: For those not fond of cold temperatures, taking a swim at 22.3°C (72.1°F) may require consideration of the sunshine, wind, and ambient temperature. While wetsuits are not mandatory, they can enhance the experience.
