The arrival of December brings an average high-temperature of a still moderately hot 27.1°C (80.8°F), closely following the temperature pattern of November. December brings with it a nighttime average temperature of 19.6°C (67.3°F).Heat index
For most parts of December, the heat index is calculated to be a hot 30°C (86°F). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
