At the start of December, Holsworthy's average high-temperature reaches a still warm 27.7°C (81.9°F), subtly different from the preceding month. December in Holsworthy, Australia, sees the temperature falling to a mean low of 17.1°C (62.8°F).Heat index
December's mean heat index is computed to be a hot 30°C (86°F). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
