December weather forecast
Alor Pongsu, Malaysia

December, the first month of the winter in Alor Pongsu, is still a hot month, with an average temperature varying between 23.4°C (74.1°F) and 30.5°C (86.9°F).

Temperature

December is the coldest month, exhibiting average temperatures of 30.5°C (86.9°F) at the peak and 23.4°C (74.1°F) at the base.

Heat index

For most parts of December, the heat index is evaluated at an extremely hot 40°C (104°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
