Weather in December
Temperature
The arrival of December sees an average high-temperature of a still warm 27.1°C (80.8°F), hardly diverging from November's 28°C (82.4°F). Throughout December, a minimal difference from peak daytime temperatures is noted, marking a steady low-temperature average of 25.9°C (78.6°F).Heat index
For December, the heat index is calculated to be a tropical 30°C (86°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
