Heat index

The average heat index in December is computed to be a fiery hot 37°C (98.6°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In December, the average relative humidity is 76%.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for average individuals.
Note: The maximum daily UV index of 7 in December interprets into the following recommendations:
Shield from overexposure. Defense against sun-related harm is required. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
