Weather in December

Throughout December, the heat index is computed to be a hot 31°C (87.8°F). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
