Weather in December
Temperature
With the onset of December, the average high-temperature registers at a still warm 27.8°C (82°F), subtly different from November's 28.6°C (83.5°F). In Harbour View, an average temperature of 22.4°C (72.3°F) is noted during December nights.Heat index
The average heat index in December is computed to be a tropical 32°C (89.6°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
