Weather in December
Temperature
The advent of December signifies a minor shift to an average high-temperature of a still tropical 31.4°C (88.5°F), aligning closely with November. Throughout the month of December, Batujaya observes an average nighttime temperature of 25.5°C (77.9°F).Heat index
The heat index for December is estimated at a sweltering 39°C (102.2°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
