Weather in December
Temperature
December is the warmest month, with an average high-temperature of 29.6°C (85.3°F) and an average low-temperature of 27.4°C (81.3°F).Heat index
The heat index value for December is computed to be a sweltering 35°C (95°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Note that heat index values are valued for light wind and location in the shade. 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 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 extremely significant for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
