Weather in December
Temperature
December's advent denotes a minor fluctuation in the average high-temperature to a still warm 27.1°C (80.8°F) from November's 24.5°C (76.1°F). December nights see a notable contrast from daytime highs, with the nighttime temperature averaging at a refreshing 14.3°C (57.7°F).Heat index
December's heat index is appraised at 28°C (82.4°F). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
