Weather in December
Temperature
The transition from November to December brings an average high-temperature of a still warm 29°C (84.2°F), barely different from November's 29.2°C (84.6°F). December nights reveal a minor deviation from daytime highs, with a mean low-temperature of 26°C (78.8°F).Heat index
December's heat index is evaluated at a tropical 34°C (93.2°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
