Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

The average relative humidity in December is 75%.
