Heat index

Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

The average relative humidity in December is 72%.
