The arrival of December brings an average high-temperature of a still warm 27.5°C (81.5°F), closely following the temperature pattern of November. Throughout December nights, Iron Knob registers an average low-temperature of 19.1°C (66.4°F).Heat index
December's average heat index is estimated at 28°C (82.4°F). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
