Weather in December
Temperature
December is marked by an average high-temperature of a still warm 28.2°C (82.8°F), almost identical to the preceding month. Nighttime, during December, brings an average low of 25.7°C (78.3°F), a modest reduction from the day's peak.Heat index
The heat index value for December is estimated at a tropical 32°C (89.6°F). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. 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 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
