Weather in December
Temperature
The dawn of December sees an average high-temperature of a still warm 29.9°C (85.8°F), subtly contrasting with November's 29.8°C (85.6°F). During December, the average low-temperature is a still moderately hot 23.8°C (74.8°F).Heat index
In December, the heat index is estimated at a very hot 37°C (98.6°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
