Weather in December
Temperature
December notes an average high-temperature of a still warm 28.6°C (83.5°F), subtly differing from November's 28.2°C (82.8°F). December nights observe an average temperature dip to an enjoyable 17.3°C (63.1°F).Heat index
December's heat index is estimated at a hot 31°C (87.8°F). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
