In Kossinna, December is the month with the lowest recorded average temperatures, measuring a high of 27.5°C (81.5°F) and a low of 19.5°C (67.1°F).Heat index
December's heat index is calculated to be a tropical 31°C (87.8°F).

Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. 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. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children.

Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
