Weather in December
Temperature
The introduction of December notes a subtle temperature variation to a still moderately hot 27.5°C (81.5°F) from November's 28.4°C (83.1°F). Uduvil's December nights experience a subtle temperature dip to an average of 26.1°C (79°F).Heat index
During December, the heat index is computed to be a tropical 31°C (87.8°F). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. 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 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
