The advent of December reveals an average high-temperature of a still moderately hot 27.3°C (81.1°F), showing minimal difference from the prior month. Throughout December, the average low-temperature dips to a comfortable 18.4°C (65.1°F).Heat index
The heat index for December is computed to be 28°C (82.4°F). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Note that heat index values are valued for light wind and location in the shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. 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 quite important for babies and toddlers. 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.
