Weather in December
Temperature
The dawn of December sees an average high-temperature of a still moderately hot 27.6°C (81.7°F), subtly contrasting with November's 28.2°C (82.8°F). Clare Valley's nocturnal average in December closely mirrors its daytime temperatures, settling at a still moderately hot 26.5°C (79.7°F).Heat index
In December, the average heat index is appraised at a hot 31°C (87.8°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 quite important for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
