Weather in December
Temperature
Bylong experiences a minor temperature shift with the start of December, with average high-temperatures moving from a moderately hot 24.8°C (76.6°F) in November to a still warm 27.8°C (82°F). December witnesses a substantial contrast between the daytime highs and the average low of 14.7°C (58.5°F).Heat index
December's heat index is appraised at 29°C (84.2°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
