The heat index value for December is calculated to be a hot 31°C (87.8°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
