Weather in December
Temperature
The transition from November to December brings a subtle temperature rise, with average high-temperatures increasing from a warm 24.8°C (76.6°F) to a still moderately hot 27.8°C (82°F). Bylong experiences a consistent, yet significant, drop from daily highs to a low-temperature of 14.7°C (58.5°F) throughout December.Heat index
The average heat index in December is computed to be 29°C (84.2°F). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. 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.
