December weather forecast
Bangar, Brunei

December brings in a dip in average temperatures in Bangar, Brunei, adding a coolness to the city's tropical climate. Despite the subtle fluctuation, the decrease in temperature does not disrupt the steady climate. The slight cooling provides a considerable contrast to the city's overall warm weather, making it a refreshing end to the year. However, rainfall heightens, reaching up to 144mm (5.67") in December, marking the advent of the rainy season. With the wind speed increasing to 6km/h (3.7mph), the weather maintains its dynamic and refreshing elements.

Bangar's weather, upon December's arrival, documents an average high-temperature of a still tropical 30.7°C (87.3°F), nearly identical to the prior month. An average nighttime temperature of 24.3°C (75.7°F) is observed in Bangar during December.

Heat index

The average heat index in December is calculated to be a blistering 41°C (105.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
