Weather in December
Temperature
The transition into December reveals an average high-temperature of a still hot 30.8°C (87.4°F), mirroring a close resemblance to November. Mjimwema's nighttime temperature in December falls to an average of 24.8°C (76.6°F).Heat index
The heat index for December is estimated at a torrid 39°C (102.2°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for 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 process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
