Weather in December
Temperature
Wollongbar's weather, upon December's arrival, documents an average high-temperature of a still moderately hot 27.6°C (81.7°F), nearly identical to the prior month. The nighttime temperature, during December, averages of 18.6°C (65.5°F).Heat index
The average heat index in December is computed to be a tropical 31°C (87.8°F). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
