Weather in December
Temperature
South Brisbane, Australia, notes an average high-temperature of a still moderately hot 27.2°C (81°F) in December, displaying minor variation from November. South Brisbane's nights in December experience an average temperature drop to an agreeable 20.8°C (69.4°F).Heat index
The heat index value during December is calculated to be a tropical 30°C (86°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
