Weather in December
Temperature
The arrival of December sees a recorded average high-temperature of a still warm 27.7°C (81.9°F), showing little divergence from the previous month's conditions. Northmead observes an average low-temperature of 17.1°C (62.8°F) during December.Heat index
The heat index value for December is calculated to be a hot 30°C (86°F). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
