Weather in December
Temperature
December is the coldest month, with an average high-temperature of 31.2°C (88.2°F) and an average low-temperature of 21.4°C (70.5°F).Heat index
December's average heat index is evaluated at a very hot 39°C (102.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
