December weather forecast
Sinda, Zambia

The first month of the summer, December, is also a moderately hot month in Sinda, Zambia, with an average temperature fluctuating between 29.5°C (85.1°F) and 20.1°C (68.2°F).

Temperature

The onset of December results in a small decrease in the average high-temperature, moderately receding from a hot 32.7°C (90.9°F) in November to a warm 29.5°C (85.1°F). Sinda experiences a steady low-temperature of 20.1°C (68.2°F) throughout December.

Heat index

In December, the heat index is evaluated at a torrid 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

The average relative humidity in December is 75%.

Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
