Weather in December

In Abasingammedda, December records the lowest average temperatures, peaking at 27.5°C (81.5°F) and reaching a low of 19.5°C (67.1°F).Heat index
December's heat index is computed to be a tropical 31°C (87.8°F). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
