Temperature

The unfolding of December shows an average high-temperature of a still hot 30.3°C (86.5°F), indicating a slight variance from November's 30.4°C (86.7°F). December nights experience a consistent temperature drop to an agreeable 22.6°C (72.7°F).

Heat index

The heat index value for December is computed to be a very hot 38°C (100.4°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Note: The daily maximum UV index of 7 in December interprets into the following advice:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
