Weather in December
Temperature
The transition from November to December brings an average high-temperature of a still warm 28.8°C (83.8°F), barely different from November's 28.4°C (83.1°F). Nights during December maintain a steady temperature, averaging at a still moderately hot 27.9°C (82.2°F).Heat index
The heat index value during December is evaluated at a tropical 33°C (91.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
