Weather in December
Temperature
As Sedayulawas, Indonesia, steps into December, the average high-temperature is measured at a still tropical 31.4°C (88.5°F), displaying minor differences from November's 33°C (91.4°F). December's average low-temperature reading settles at a warm 25.5°C (77.9°F).Heat index
The average heat index in December is evaluated at a blistering 41°C (105.8°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical 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 highly critical to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary.
