Weather in December
Temperature
December's beginning signals an average high-temperature of a still warm 27.2°C (81°F), barely different from November's 26.5°C (79.7°F). December nights are marked by an average temperature drop to an agreeable 20.8°C (69.4°F).Heat index
In December, the average heat index is estimated at a tropical 30°C (86°F). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
