Weather in December
Temperature
December experiences an average high-temperature of a still warm 27.2°C (81°F), barely different from November's 27.5°C (81.5°F). An average low-temperature of 17°C (62.6°F) is observed during the December nights.Heat index
The heat index value for December is calculated to be 29°C (84.2°F). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
