Weather in December
Temperature
December, with an average high of 29.8°C (85.6°F) and a low of 24.1°C (75.4°F), signifies the coldest month of the year.Heat index
December's average heat index is calculated to be a fiery hot 36°C (96.8°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', comes about by integrating the temperature readings with the humidity levels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for average individuals.Note: In December, the average maximum UV index of 7 translates into the following recommendations:
Shun overexposure. Protection from sun ravages is indispensable. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
