Weather in December
Temperature
December's onset records an average high-temperature of a still moderately hot 27.1°C (80.8°F), a near match to November's 27.9°C (82.2°F). During December, an average low-temperature of 19.6°C (67.3°F) is observed.Heat index
The heat index value for December is computed to be a hot 30°C (86°F). Constant activity during exposure could result in a state of weariness and possibly heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
