December weather forecast
Bukit Tambun, Malaysia

December, the first month of the winter in Bukit Tambun, is still a hot month, with an average temperature varying between 23.4°C (74.1°F) and 30.6°C (87.1°F).

Temperature

With its high average temperature of 30.6°C (87.1°F) and a low of 23.4°C (74.1°F), December is regarded as the coldest month.

Heat index

December's mean heat index is calculated to be a blisteringly hot 41°C (105.8°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
