Weather in December
Temperature
As November turns into December, the average high-temperatures rest at a still moderately hot 29°C (84.2°F), showing a minor variation from the prior month. During December, the nighttime temperature averages to a still moderately hot 23.8°C (74.8°F).Heat index
In December, the average heat index is calculated to be a sweltering 36°C (96.8°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. 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 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
