Weather in December
Temperature
The commencement of December brings an average high-temperature of a still warm 27.5°C (81.5°F), marking an inconsequential divergence from November. December registers an average low temperature of 24.9°C (76.8°F), subtly lower than the daytime maximum.Heat index
December's mean heat index is computed to be a tropical 31°C (87.8°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. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
