Weather in December
Temperature
December, marked by an average high-temperature of 31.5°C (88.7°F) and a low-temperature of 21°C (69.8°F), is the warmest month.Heat index
December's mean heat index is calculated to be a sweltering 38°C (100.4°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. 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 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 hold great significance to children. 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. 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. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

In Letsitele, the average daily maximum UV index in December is 6. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: In December, a daily maximum UV index of 6 leads to the following instructions:
Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
