Weather in December
Temperature
As Yumbi steps into December, the average high-temperature is measured at a still hot 31.5°C (88.7°F), displaying minor differences from November's 30°C (86°F). During the nights in December, an average low-temperature of 22.3°C (72.1°F) is observed.Heat index
The heat index value for December is estimated at a blisteringly hot 40°C (104°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
