Heat index

December's mean heat index is estimated at a fiery hot 36°C (96.8°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

In December, the average relative humidity is 56%.
