Weather in December
Temperature
December's onset records an average high-temperature of a hot 34.8°C (94.6°F), a near match to November's 36.3°C (97.3°F). December nights observe an average temperature dip to a warm 24°C (75.2°F).Heat index
The heat index in December is evaluated at a scorching 44°C (111.2°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
