Weather in December
Temperature
Banda Aceh experiences its lowest temperatures in December, with an average peak of 28.9°C (84°F) and a low of 24.3°C (75.7°F).Heat index
December's average heat index is appraised at a torrid 35°C (95°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for ordinary individuals.Note: The maximum UV index of 7 during December leads to these instructions:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
