For most parts of December, the heat index is calculated to be 27°C (80.6°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
