Weather in December
Temperature
Narrabri transitions into December recording an average high-temperature of a still tropical 32.5°C (90.5°F), closely aligning with the preceding month's temperature. During the month of December, an average low-temperature of 21.2°C (70.2°F) is recorded.Heat index
During December, the heat index is evaluated at a torrid 35°C (95°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
