Weather in December
Temperature
December welcomes an average high-temperature of a still warm 27.5°C (81.5°F), not much different from the preceding month. Nights in December cool down, indicating a minor disparity from daytime highs with an average low-temperature of 24.9°C (76.8°F).Heat index
December's mean heat index is calculated to be a hot 31°C (87.8°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
