Weather in December
Temperature
The coldest period tends to be December, when average temperatures fluctuate between a high of 28.6°C (83.5°F) and a low of 20.4°C (68.7°F).Heat index
The heat index in December is estimated at a tropical 34°C (93.2°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
