Heat index

In December, the heat index is computed to be a sweltering 37°C (98.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Humidity

In December, the average relative humidity is 65%.
